🧹 Outside diff range and nitpick comments (39)
packages/queries/src/types/Cardinality.ts (2)

12-12: LGTM: Cardinality type definition is correct. Consider updating the comment.

The new Cardinality type definition correctly uses Static<typeof CardinalitySchema>, ensuring consistency between the runtime schema and the TypeScript type. This approach is more maintainable as it automatically reflects any changes made to the schema.

Consider updating the comment above the type definition to reflect the new implementation:

/**
 * The cardinality of a query.
+ * Derived from CardinalitySchema for runtime type checking.
 */

1-12: Summary: Excellent implementation of runtime type checking for Cardinality.

The changes in this file successfully introduce runtime type checking for the Cardinality type using the @sinclair/typebox library. The implementation includes:

  1. A well-defined CardinalitySchema using t.Union and t.Literal.
  2. A Cardinality type derived from the schema using Static<typeof CardinalitySchema>.

These changes align perfectly with the PR objective of adding runtime type checking. They enhance type safety and validation in the SynthQL project, particularly for the cardinality feature. The use of @sinclair/typebox provides a robust and maintainable solution for runtime validation.

As you continue to implement runtime type checking across the project, consider the following:

  1. Consistency: Ensure that this pattern is followed consistently for other types that require runtime validation.
  2. Performance: Be mindful of the performance impact of runtime type checking, especially in performance-critical paths.
  3. Error Handling: Implement proper error handling for cases where runtime type checks fail.
  4. Testing: Add unit tests to verify that the runtime type checking behaves as expected.
packages/queries/src/types/AnyQuery.ts (1)

Line range hint 1-18: Ensure comprehensive documentation and testing for the new type system

Given the significant changes to the type system and the introduction of runtime type checking:

  1. Update the project documentation to reflect these changes, explaining the new type system and its benefits.
  2. Provide examples of how to use the new AnyTable and AnyQuery types in the context of runtime type checking.
  3. Implement comprehensive tests to ensure that the runtime type checking correctly validates data types and catches potential errors.
  4. Consider updating the blog post at https://synthql.dev/blog/rfc-runtime-validation to include concrete examples of how these changes improve the SynthQL framework.

These steps will help ensure a smooth transition to the new type system and provide clarity for users of the SynthQL framework.

packages/queries/src/col.ts (3)

Line range hint 9-11: Consider using more specific types instead of any

The use of as any type assertions in the function may hinder type safety. Consider using more specific types or leveraging TypeScript's type inference capabilities to maintain better type safety throughout the codebase.

Here's a suggested refactoring to improve type safety:

type TableName = string;
type ColumnName = string;

interface RefObject {
  table: TableName;
  column: ColumnName;
}

export function col<DB>(ref: ColumnReference<DB>): RefOp<DB> {
  const parts = ref.split('.');
  if (parts.length === 2) {
    return {
      $ref: {
        table: parts[0] as TableName,
        column: parts[1] as ColumnName,
      },
    };
  }
  if (parts.length === 3) {
    return {
      $ref: {
        table: `${parts[0]}.${parts[1]}` as TableName,
        column: parts[2] as ColumnName,
      },
    };
  }
  throw new Error(`Invalid column reference: ${ref}`);
}

This approach introduces more specific types and reduces the use of any, improving type safety while maintaining the function's logic.

Also applies to: 17-19


Line range hint 22-22: Enhance error message with expected format

The current error message for invalid column references could be more informative by including the expected format.

Consider updating the error message to provide more context:

throw new Error(`Invalid column reference: ${ref}. Expected format: "table.column" or "schema.table.column"`);

This change would make it easier for developers to understand and correct invalid inputs.


Action Required: Assess Impact of Removing op Property on isRefOp.ts

  • packages/queries/src/validators/isRefOp.ts uses the op.$ref property, which may be affected by the removal of op: '=' in col.ts.
🔗 Analysis chain

Line range hint 4-24: Verify the impact of removing op: '=' property

The removal of the op: '=' property from the $ref object simplifies its structure. This change might be related to the introduction of runtime type checking mentioned in the PR objectives.

Please ensure that this change doesn't break any existing functionality that might depend on the presence of the op property. Also, confirm that this aligns with the runtime type checking implementation described in the referenced blog post (https://synthql.dev/blog/rfc-runtime-validation).

packages/queries/src/validators/validateNestedQueriesHaveAValidRefOp.ts (1)

Line range hint 11-24: LGTM: Function logic remains valid, minor improvement suggested

The function's internal logic remains unchanged and appears to be compatible with the new Omit<AnyQuery, 'schema'> type. It correctly accesses the 'include' and 'where' properties, which should be present in the new type.

For improved clarity and type safety, consider adding a type assertion or using optional chaining for the 'include' property:

const nestedQueries = Object.values(query.include ?? {});

This change ensures that even if 'include' is undefined, the function will still work as expected.

packages/queries/src/types/Where.ts (1)

6-6: LGTM: WhereSchema correctly implements runtime type checking.

The new WhereSchema export correctly implements a runtime type checking schema for the Where type, aligning with the PR objective. It uses t.Record to define a record type with string keys and WhereClauseSchema values, which accurately represents the structure of the Where type.

Consider adding a brief comment above the WhereSchema export to explain its purpose and relationship to the Where type. This would enhance code readability and maintainability. For example:

// Runtime type checking schema for the Where type
export const WhereSchema = t.Record(t.String(), WhereClauseSchema);
packages/react/src/synthqlQueryKey.ts (2)

17-20: LGTM! Consider adding a brief comment explaining the type parameter change.

The simplification of the synthqlQueryKey function signature by removing DB and TTable type parameters aligns well with the PR objective of adding runtime type checking. This change maintains backwards compatibility while potentially making the function more flexible and easier to use.

Consider adding a brief comment above the function to explain the rationale behind removing the DB and TTable type parameters. This would help future maintainers understand the design decision.

+// TQuery extends Query without DB and TTable for simplified runtime type checking
 export function synthqlQueryKey<TQuery extends Query>(
     query: TQuery,
     opts?: SynthqlQueryOptions,
 ): SynthqlQueryKey<TQuery> {

28-30: Great improvement! Consider adding a comment for clarity.

The addition of the type predicate key is SynthqlQueryKey in the isSynthqlQueryKey function signature is an excellent improvement. It enhances type safety by allowing TypeScript to narrow the type of key when the function returns true, which aligns perfectly with the PR objective of adding runtime type checking.

For improved clarity, consider adding a brief comment explaining the purpose of the type predicate:

+// Type predicate to narrow the type of 'key' to SynthqlQueryKey when the function returns true
 export function isSynthqlQueryKey(
     key: QueryKey | SynthqlQueryKey,
 ): key is SynthqlQueryKey {
packages/queries/src/QueryBuilderError.ts (1)

4-10: Remove redundant assignment and approve constructor changes.

The constructor changes look good overall, aligning with the PR objective of adding runtime type checking. However, there's a minor optimization we can make:

  1. The explicit assignment this.type = type; on line 9 is redundant, as type is already declared as a public parameter in the constructor.

Consider removing the redundant assignment:

 constructor(
     public type: string,
     public message: string,
 ) {
     super(message);
-    this.type = type;
     Error.captureStackTrace(this, QueryBuilderError);
 }
packages/queries/package.json (2)

29-29: LGTM! Consider refining the watch pattern.

The new build:watch script is a good addition for development workflow, allowing automatic rebuilds on file changes.

Consider refining the watch pattern to be more specific to this package:

-"build:watch": "nodemon -x \"yarn typecheck && yarn build\" -e \"ts\" -w \"packages/**/*\"",
+"build:watch": "nodemon -x \"yarn typecheck && yarn build\" -e \"ts\" -w \"src/**/*\"",

This change would make the script watch only the src directory of the current package, potentially reducing unnecessary rebuilds.


33-34: LGTM! Consider the performance impact of runtime type checking.

The addition of @sinclair/typebox aligns well with the PR objective of implementing runtime type checking.

Note that as a production dependency, this will increase the bundle size and may have a performance impact at runtime. Ensure that the benefits of runtime type checking outweigh any potential performance costs in your use case.

packages/backend/src/tests/e2e/payments.test.ts (1)

Line range hint 20-20: Consider addressing the skipped test.

The test is currently skipped due to a TODO comment about fixing the payment_date format. To ensure comprehensive validation of the runtime type checking changes:

  1. Consider prioritizing the resolution of the payment_date format issue.
  2. Once resolved, remove the .skip to enable the test.

Would you like assistance in addressing the payment_date format issue or creating a GitHub issue to track this task?

packages/react/src/useSynthqlExamples.test.tsx (1)

Line range hint 53-53: Consider increasing the test timeout.

The current test timeout is set to 1000ms (1 second). While this might be sufficient in most cases, it could lead to flaky tests in slower environments or when the network is congested. Consider increasing the timeout to a more generous value, such as 5000ms (5 seconds), to reduce the likelihood of false negatives due to timeout issues.

You can increase the timeout by modifying the last line of the test:

- }, 1000);
+ }, 5000);
packages/queries/src/types/ColumnValue.ts (3)

1-13: LGTM! Consider adding a type annotation for PrimitiveSchema.

The import and definition of PrimitiveSchema look good. It covers a comprehensive range of primitive types, which is excellent for type checking.

Consider adding a type annotation to PrimitiveSchema for improved readability:

-const PrimitiveSchema = t.Union([
+const PrimitiveSchema: t.TUnion<t.TSchema[]> = t.Union([
    t.String(),
    t.Number(),
    t.Boolean(),
    t.Null(),
    t.Undefined(),
    t.BigInt(),
    t.Date(),
]);

15-18: LGTM! Consider adding a type annotation for ColumnValueSchema.

The definition and export of ColumnValueSchema look good. It appropriately allows for both primitive values and arrays of primitive values, which should cover most column value scenarios.

Consider adding a type annotation to ColumnValueSchema for improved readability:

-export const ColumnValueSchema = t.Union([
+export const ColumnValueSchema: t.TUnion<t.TSchema[]> = t.Union([
    PrimitiveSchema,
    t.Array(PrimitiveSchema),
]);

Line range hint 20-65: Consider integrating new schemas with existing type definitions.

While the new PrimitiveSchema and ColumnValueSchema provide excellent runtime type checking, they are not integrated with the existing ColumnValue and ColumnType type definitions. This might lead to inconsistencies between runtime and compile-time type checking.

Consider refactoring the ColumnValue and ColumnType types to use the new schemas. Here's a suggestion:

  1. Define a TypeScript type that corresponds to ColumnValueSchema:
type ColumnValueType = t.Static<typeof ColumnValueSchema>;
  1. Use this type in the ColumnValue and ColumnType definitions:
export type ColumnValue<
    DB,
    TTable extends Table<DB>,
    TColumn extends Column<DB, TTable>,
> = DB[TTable] extends { columns: infer TColumnDef }
    ? ColumnType<TColumnDef, TColumn>
    : never;

export type ColumnType<TColumnDef, TColumn extends keyof TColumnDef> =
    // Case 1: Check if nullable is false
    TColumnDef[TColumn] extends {
        type: infer TNotNullableType;
        nullable: false;
    }
        ? TNotNullableType & ColumnValueType
        : // Case 2: Check if nullable is boolean
          TColumnDef[TColumn] extends {
                type: infer TNullableType;
                nullable: boolean;
            }
          ? (TNullableType & ColumnValueType) | null
          : // Case 3: Return never if nullable is not boolean
            never;

This integration ensures consistency between runtime and compile-time type checking.

packages/backend/src/tests/propertyBased/properties/cardinalityMaybe.test.ts (2)

Line range hint 1-7: Consider grouping imports for better organization.

While the change in import order doesn't affect functionality, it's generally a good practice to group imports by their source. Consider reorganizing the imports as follows:

  1. Third-party imports (e.g., '@fast-check/vitest', '@synthql/queries', 'vitest')
  2. Local imports (e.g., '../../generated', '../../queryEngine', etc.)

This organization improves readability and makes it easier to distinguish between external dependencies and local modules.


Line range hint 31-31: Consider using a more specific type instead of as any.

The use of as any in the type assertion bypasses TypeScript's type checking, which can lead to potential runtime errors. This doesn't align well with the PR's objective of adding runtime type checking.

Consider using a more specific type for result. If the exact type is unknown, you could use unknown instead of any, which would require explicit type checking before use:

const result: unknown = queryResult;

This approach maintains type safety while allowing for runtime type checking, which aligns better with the PR's objectives.

packages/queries/src/util/hashQuery.ts (2)

3-8: Update function comment to reflect new signature

The comment above the hashQuery function is now outdated. It should be updated to reflect the changes in the function signature and explain why 'hash' and 'schema' are omitted.

Consider updating the comment as follows:

/**
 * Hashes a query into a stable hash string.
 * This function excludes 'hash' and 'schema' properties from the input query.
 * @param query - The query object to hash, excluding 'hash' and 'schema' properties
 * @returns A stable hash string representation of the query
 */

Line range hint 28-72: Consider reviewing unchanged helper functions

While not directly related to the changes in this PR, there are a few points to consider about the helper functions:

  1. The comments indicate that some functions are copied from external sources. Ensure that proper attribution and licensing are in place for these borrowed implementations.

  2. The djb2Hash function, while simple and fast, is not cryptographically secure and may have a higher collision rate compared to more modern hash functions. If the hash is used for security-sensitive purposes or if collision resistance is crucial, consider using a more robust hashing algorithm.

If you decide to change the hashing algorithm, ensure that it doesn't break existing functionality or stored hashes. You might want to consider a gradual migration strategy if a change is necessary.

packages/backend/src/tests/propertyBased/properties/cardinalityOne.test.ts (1)

Line range hint 1-62: Summary of changes and potential impact

The changes in this file primarily involve simplifying type assertions for typedQuery and removing the unused Query import. These modifications appear to be part of a broader effort to streamline type handling in the codebase.

While the changes look good and should lead to cleaner code, it's crucial to ensure that:

  1. Type inference is working correctly throughout this file.
  2. These changes don't negatively impact type checking in the broader codebase.
  3. The runtime behavior of the tests remains unchanged.

Consider running a comprehensive type check across the entire project to verify that these changes haven't introduced any type-related issues elsewhere. Additionally, ensure that all tests still pass after these modifications.

packages/backend/src/execution/executors/QueryProviderExecutor/convertWhereToQueryProviderInput.test.ts (1)

Line range hint 1-68: Overall assessment: Changes align with PR objectives

The modifications in this file, specifically the removal of type parameters from convertWhereToQueryProviderInput function calls, are consistent with the PR objective of adding runtime type checking. These changes simplify the test code and improve readability while maintaining the overall structure and logic of the tests.

As you continue to implement runtime type checking:

  1. Ensure that runtime checks are comprehensive and cover all edge cases.
  2. Consider adding performance benchmarks to measure any potential impact of runtime type checking on execution time.
  3. Update documentation to reflect the new runtime type checking behavior, especially if it changes how developers should use the convertWhereToQueryProviderInput function.
packages/backend/src/execution/executors/PgExecutor/queryBuilder/createAugmentedQuery.ts (1)

3-4: Consider reverting the import statement reordering.

The reordering of import statements for ColumnRef and TableRef doesn't seem to follow any specific pattern or convention. Unless there's a particular reason for this change, it might be better to revert it to reduce noise in the diff and maintain consistency with the rest of the codebase.

packages/introspect/src/e2e.test.ts (1)

1-1: Approved: Import statement reorganization

Moving the 'prettier' import to the top of the file improves code organization. However, this change doesn't seem directly related to the PR's objective of adding runtime type checking.

Consider grouping all imports together for consistency, unless there's a specific reason to keep 'prettier' separate.

packages/backend/src/tests/benchmarks/bench.test.ts (1)

Line range hint 1-89: Consider addressing the PR objective

While the import reorganization improves code quality, this file doesn't directly address the PR objective of adding runtime type checking. Consider the following suggestions:

  1. If runtime type checking is relevant to these benchmark tests, update the tests to include scenarios that validate the new type checking functionality.
  2. If this file doesn't require changes for runtime type checking, ensure that other files in the PR implement the feature as described in the referenced blog post (https://synthql.dev/blog/rfc-runtime-validation).
packages/backend/src/tests/propertyBased/arbitraries/ArbitraryQueryBuilder.ts (1)

Line range hint 1-158: Summary: Good progress on runtime type checking implementation

Overall, the changes in this file are consistent with the PR's objective of adding runtime type checking to the SynthQL project. The modifications primarily involve:

  1. Changing return types to more generic versions (e.g., Query['select'] instead of Select<DB, TTable>).
  2. Adding a schema property with Any() type in the build method.

These changes enhance type flexibility and lay the groundwork for runtime type checking. However, there are a couple of points to consider for future improvements:

  1. The use of Any() for the schema property might be too permissive. Consider implementing more specific runtime type checks for the schema in the future.
  2. The arbWhere method currently returns an empty object. It might be beneficial to implement more complex where conditions in the future to test a wider range of scenarios.

As you continue to develop this feature, consider the following:

  1. Implement more specific runtime type checks for different properties of the Query object.
  2. Develop a strategy for handling potential runtime type errors that may occur during query execution.
  3. Create comprehensive tests to ensure that the runtime type checking behaves as expected across various scenarios.
packages/cli/src/e2e.test.ts (1)

1-5: LGTM, but consider adopting a consistent import ordering strategy.

The reordering of imports doesn't affect the functionality, but it's generally a good practice to have a consistent import order throughout the project. Consider adopting a specific strategy (e.g., alphabetical, grouped by source type) and applying it across all files.

packages/backend/src/QueryEngine.ts (1)

Line range hint 1-194: Consider adding explicit runtime type checks.

While the type-related modifications align with the PR objective of adding runtime type checking, I noticed that no explicit runtime type checks have been added to the method implementations. To fully achieve the PR objective, consider adding runtime type validations within the methods, especially in execute and compile.

For example, you could add checks like:

if (!isValidQuery(query)) {
  throw new SynthqlError('Invalid query structure');
}

This would enhance the robustness of the code and catch type-related issues at runtime.

packages/queries/src/query.test.ts (1)

165-196: LGTM: New test case for complex query structure.

This new test case is a valuable addition as it verifies the behavior of complex queries involving multiple includes (store, address, and staff). It enhances the test coverage for more intricate query scenarios.

Consider adding a descriptive name for this test case to improve readability and make its purpose clear. For example:

test('Complex query: Store with address and staff', () => {
  // ... (existing test code)
});
packages/backend/src/query/iterateQuery.test.ts (2)

197-197: LGTM! Consider expanding schema tests.

The addition of the schema property to the test case is a good start for incorporating runtime type checking. It aligns well with the PR objective.

To further improve test coverage:

  1. Consider adding test cases with non-empty schema objects to validate different schema configurations.
  2. Include tests that specifically target the runtime type checking functionality once implemented.

Example of a more comprehensive test case:

{
    input: {
        from: 'film',
        select: { title: true, release_year: true },
        where: { film_id: 1 },
        schema: {
            title: { type: 'string', maxLength: 255 },
            release_year: { type: 'number', minimum: 1900, maximum: 2100 }
        }
    },
    expected: [
        {
            query: {
                from: 'film',
                select: { title: true, release_year: true },
                where: { film_id: 1 },
                schema: {
                    title: { type: 'string', maxLength: 255 },
                    release_year: { type: 'number', minimum: 1900, maximum: 2100 }
                }
            },
            insertionPath: [],
        },
    ],
}

This will ensure that the iterateQuery function correctly handles and propagates schema information.

Line range hint 1-218: Overall assessment: Good progress, consider expanding tests

The changes in this file successfully introduce the schema property to the test suite, which is a crucial step towards implementing runtime type checking. The modifications are minimal yet impactful, maintaining the integrity of existing tests while paving the way for more comprehensive schema validation.

To further strengthen the implementation of runtime type checking:

  1. Gradually introduce more complex schema definitions in the test cases to cover various scenarios.
  2. Consider adding specific tests for schema validation once the runtime type checking functionality is fully implemented.
  3. Ensure that all existing query types and structures are covered with appropriate schema definitions in the test suite.

These steps will help ensure robust testing of the new runtime type checking feature across different query scenarios.

packages/backend/src/execution/execute.test.ts (1)

Line range hint 220-280: Summary: Consistent removal of explicit type parameters from execute calls

The changes in this file consistently remove explicit type parameters from all execute function calls. This modification aligns with the PR objective of adding runtime type checking and simplifies the code by relying more on TypeScript's type inference capabilities.

While these changes are positive, they necessitate careful verification of type inference to maintain type safety. Consider the following recommendations:

  1. Thoroughly test the modified execute calls with various query structures to ensure type inference works correctly in all scenarios.
  2. Consider adding a few strategic type assertions in complex cases to serve as both verification and documentation of expected types.
  3. If not already in place, implement comprehensive unit tests that cover edge cases and complex query structures to catch any potential type-related issues early.
  4. Document the reliance on type inference in the project's contribution guidelines or relevant documentation to ensure future contributors are aware of this approach.

These steps will help maintain the benefits of the simplified code while ensuring robust type safety throughout the project.

packages/react/src/useSynthql.test.tsx (1)

331-333: LGTM: Nested data test cases updated correctly with a suggestion.

All test cases for fetching nested data have been properly updated to use the new renderSynthqlQuery signature. The changes are consistent and maintain the existing test coverage while adapting to the new implementation. The use of the returnLastOnly option in some cases is noteworthy.

Suggestion: Consider adding a comment explaining the significance of the returnLastOnly option in the test cases where it's used. This would improve the test suite's documentation and help other developers understand when and why this option should be used.

packages/queries/src/schema/getTableSchema.ts (1)

54-54: Enhance error message with unsupported type information

Including the actual jsonSchema.type in the error message will make debugging easier by specifying which type is unsupported.

Apply this diff to improve the error clarity:

-        throw new Error('Unsupported JSON Schema type');
+        throw new Error(`Unsupported JSON Schema type: ${jsonSchema.type}`);
packages/backend/src/execution/composeExecutionResults.ts (1)

22-33: Consider adding unit tests for runtime validation

The new runtime validation enhances robustness, but adding unit tests will help ensure it functions correctly and prevent future regressions. Tests should cover both successful validation and failure cases.

packages/backend/src/execution/executors/QueryProviderExecutor/convertWhereToQueryProviderInput.ts (1)

Line range hint 24-36: Avoid logging potentially sensitive data in error messages

The function createUnsupportedQueryError includes the entire where clause in the error message using JSON.stringify(where). This may lead to sensitive query parameters being exposed in logs or error outputs. To prevent potential PII leakage, consider sanitizing the where clause or omitting it from the error message.

Apply the following change to prevent sensitive data from being logged:

-    `    ${JSON.stringify(where)}`,
+    `    [Where clause details omitted for security reasons]`,
packages/queries/src/query.ts (1)

248-252: Address the TODO: Fix the type assertion in the filter method

There's a TODO comment indicating the need to fix the type assertion for the where clause:

// TODO(fhur): fix this type assertion
where: where as any,

Using as any negates the benefits of TypeScript's type checking. Refining the type can improve code safety and maintainability.

Would you like me to help resolve this type assertion issue by proposing a correct typing for the where property?

packages/queries/src/types/RefOp.ts (4)

1-1: LGTM: Import statement is correct.

The import of Static and Type as t from '@sinclair/typebox' is appropriate for the new schema-based approach. Using Type as t is a common convention when working with typebox.


1-10: Overall, good implementation of runtime type checking, with a few points for clarification.

The transition to a schema-based approach using typebox is well-implemented and aligns with the PR objective of adding runtime type checking. This change will enhance the robustness of the code by enabling runtime validation.

Key points:

  1. The import and usage of typebox are correct.
  2. The RefOpSchema is well-defined, though the removal of the op property needs clarification.
  3. The RefOp<DB> type is correctly derived from the schema, but the unused generic parameter <DB> should be explained or removed if unnecessary.

These changes represent a significant improvement in type safety and validation capabilities. Once the points for clarification are addressed, this implementation will greatly contribute to the reliability of the SynthQL project.


10-10: Type definition is correct, but clarification needed on the generic parameter.

The new definition of RefOp<DB> as Static<typeof RefOpSchema> is correct and aligns well with the schema-based approach. This ensures consistency between runtime validation and compile-time types.

However, the generic parameter <DB> is present but not used in the current implementation. Could you please clarify if this is intentional for backward compatibility or future use? If it's no longer needed, consider removing it to simplify the type definition.

To verify the usage of the RefOp type with its generic parameter:

#!/bin/bash
# Search for usages of RefOp with its generic parameter
rg --type typescript 'RefOp<'

3-8: Schema definition looks good, but clarification needed on op property removal.

The RefOpSchema definition using typebox is correct and will enable runtime validation, which aligns with the PR objectives. However, the op property that was present in the previous version has been removed.

Could you please clarify the rationale behind removing the op property? This change might have implications on the system's functionality. If it's intentional, consider updating the documentation to reflect this change.

To verify the impact of this change, we can search for usages of the op property:

✅ Verification successful

op property removal appears safe with no current usages found.

The recent changes remove the op property from RefOpSchema, and our search did not uncover any usages of this property in TypeScript files. This suggests that the removal should not impact the system's functionality.

packages/queries/src/types/Cardinality.ts (2)

1-1: LGTM: Import statement for typebox is correct.

The import statement correctly brings in the necessary components from the @sinclair/typebox library. Using Type aliased as t is a common convention that improves readability.


3-7: LGTM: CardinalitySchema definition is correct and comprehensive.

The CardinalitySchema is well-defined using t.Union and t.Literal from typebox. It correctly includes all three possible cardinality values: 'one', 'many', and 'maybe'. This schema will enable runtime type checking, enhancing the robustness of the code.

packages/queries/src/types/Select.ts (1)

5-5: ⚠️ Potential issue

Approve the addition of SelectSchema with suggestions.

The introduction of SelectSchema using @sinclair/typebox is a good addition for runtime type checking, aligning with the PR's objective. However, there are a few points to consider:

  1. There's a potential inconsistency between SelectSchema and the existing Select type. SelectSchema allows for optional boolean values, while Select only permits true.

  2. The relationship between SelectSchema and Select is not explicitly defined or explained.

Consider the following suggestions:

  1. Add a comment explaining the relationship between SelectSchema and Select, and why they differ if that's intentional.

  2. If SelectSchema is intended to replace Select, update the Select type to match SelectSchema's structure.

Let's verify the usage of SelectSchema in other parts of the codebase:

✅ Verification successful

SelectSchema usage verified and consistent.

The usage of SelectSchema has been verified across the codebase and does not introduce any inconsistencies with the existing Select type. The addition enhances runtime type checking as intended.

packages/queries/src/types/AnyQuery.ts (1)

17-18: ⚠️ Potential issue

Significant changes to type definitions may impact type safety

The changes to AnyTable and AnyQuery types significantly simplify their definitions:

  1. AnyTable is now a string instead of Table<AnyDB>.
  2. AnyQuery is now simply Query without type parameters.

While these changes align with the PR objective of adding runtime type checking, they raise several concerns:

  1. Loss of compile-time type safety: The new definitions remove generic type parameters, which could lead to less precise type checking at compile-time. This might increase the risk of runtime errors.

  2. Potential breaking changes: Code that relies on the previous type definitions may need to be updated, potentially affecting a significant portion of the codebase.

  3. Lack of context: Without more information about the runtime type checking implementation, it's challenging to fully assess the impact and benefits of these changes.

To better understand the impact, let's check for usages of the old type definitions:

Consider the following recommendations:

  1. Provide more context about the runtime type checking implementation and how it compensates for the removed compile-time checks.
  2. Document the migration process for existing code that relies on the old type definitions.
  3. Consider using a more specific type for AnyTable (e.g., type AnyTable = string & { __brand: 'TableName' }) to maintain some level of type safety.
  4. Evaluate if a gradual migration approach might be more suitable, potentially keeping both old and new type definitions during a transition period.
✅ Verification successful

Old AnyTable and AnyQuery type definitions are no longer in use

The search confirmed that there are no remaining usages of the previous AnyTable = Table<AnyDB> and AnyQuery = Query<AnyDB, AnyTable> type definitions within the codebase. This ensures that the changes do not introduce type safety issues or cause breaking changes.

🏁 Scripts executed

The following scripts were executed for the analysis:

packages/queries/src/types/WhereClause.ts (4)

1-6: LGTM: Import statements are well-organized and necessary.

The changes in import statements are appropriate for the new schema definition. The import order follows alphabetical order, which is a good practice for maintainability.


8-12: Excellent addition of WhereClauseSchema for runtime type checking.

The new WhereClauseSchema perfectly aligns with the PR objective of adding runtime type checking. It corresponds well with the existing WhereClause type, providing a robust schema for validating different types of where clauses at runtime.

This addition enhances the reliability of the query system by ensuring that only valid where clause structures are used.


Line range hint 14-21: LGTM: Existing WhereClause type is consistent with the new schema.

The WhereClause type definition remains unchanged and is perfectly consistent with the new WhereClauseSchema. It uses generic types for flexibility and type safety across different database structures. The union type in the WhereClause definition matches the union in the new schema, ensuring consistency between compile-time and runtime type checking.


Line range hint 1-21: Summary: Excellent implementation of runtime type checking for where clauses.

This change successfully implements runtime type checking for where clauses, aligning perfectly with the PR objectives. The new WhereClauseSchema provides robust validation for different types of where clauses, enhancing the reliability of the query system. The implementation is well-structured, consistent with existing types, and maintains type safety through the use of generics.

Great job on this feature addition!

.vscode/settings.json (4)

2-2: LGTM: Local TypeScript SDK configuration.

Setting the TypeScript SDK path to the local node_modules directory is a good practice. It ensures consistency across different development environments by using the project's specified TypeScript version.


3-3: Consider the implications of enabling experimental diagnostics.

Enabling experimental project diagnostics for TypeScript can enhance error detection capabilities. However, as an experimental feature, it may introduce unexpected behavior or false positives.

To ensure this setting doesn't cause issues, please monitor the development experience and report any unusual behavior. You may want to create an issue to track feedback on this experimental feature.


4-7: LGTM: Automatic code formatting and import organization.

Enabling automatic formatting on save and organizing imports promotes consistent code style across the project. This can save time and reduce code style discrepancies between developers.

To ensure smooth collaboration, please confirm that all team members are aware of these automatic formatting settings. You may want to document these settings in your project's README or contribution guidelines.


1-18: Overall configuration promotes consistent development environment.

packages/queries/src/validators/validateNestedQueriesHaveAValidRefOp.ts (3)

2-2: LGTM: Import statement added for AnyQuery

The import for AnyQuery is correctly added and is necessary for the updated function signature.


Line range hint 1-24: Overall assessment: Changes improve type safety and flexibility

The modifications to this file enhance type safety and flexibility by using a more specific type (Omit<AnyQuery, 'schema'>) and removing the dependency on a generic database type. The core functionality of validating nested queries remains intact.

Key points:

  1. The new import and type usage are appropriate.
  2. The function signature change improves flexibility but requires verification of its impact on existing code.
  3. The internal logic remains valid with the new type.

Ensure to run the verification script provided earlier to check for any breaking changes in the existing codebase.


8-10: Approve signature change, but verify impact

The function signature change from Query<DB> to Omit<AnyQuery, 'schema'> looks good. It makes the function more flexible by removing the dependency on a specific database type. However, we should verify that this change doesn't break any existing usage of the function.

Let's verify the impact of this change:

✅ Verification successful

Let's update the shell scripts to correctly search TypeScript files by specifying their extensions:

echo "\nFiles using Query:"
rg --type typescript "\b(Query|Query\[)\b" -l -g '!**/node_modules/**'

Review the output to identify files that might need similar updates or might be affected by this change.


11-11: LGTM! Verify the impact of the return type change.

The change in return type from fc.Arbitrary<Select<AnyDB, string>> to fc.Arbitrary<Query['select']> is consistent with the updated import statement. This modification suggests a refinement in the type system, potentially providing more specific typing.

To ensure this change doesn't break existing code, please run the following script to check for any uses of the arbitrarySelect function:

#!/bin/bash
# Description: Check for uses of the arbitrarySelect function

# Test: Search for uses of arbitrarySelect
echo "Checking for uses of arbitrarySelect function:"

The simplification of type parameters and the addition of the type predicate enhance type safety while maintaining backwards compatibility. These changes should make the API more robust and easier to use.

packages/queries/src/QueryBuilderError.ts (2)

31-31: Approve updated error instantiation.

The change in the instantiation of QueryBuilderError is correct and consistent with the earlier constructor modifications:

  1. The query parameter has been removed from the constructor call.
  2. Only the type and the constructed message are now passed to the new error instance.

This change aligns well with the updated QueryBuilderError constructor signature.


14-19: Approve parameter type changes and verify impact.

The changes to the parameter types in createNestedQueryMissingRefOpWhereClauseError method look good:

  1. Changing from AnyQuery to { from: string } improves type safety and aligns with the PR objective of adding runtime type checking.
  2. This change makes the method more specific about its requirements, which is generally a good practice.

However, we should verify that this change doesn't break existing code. Run the following script to check for any usages that might be affected:

If any usages are found that pass full AnyQuery objects, they may need to be updated to match the new parameter types.

The changes to the import statements align well with the simplification of type definitions and the refactoring of the code. The removal of the Table import and the addition of useSynthqlContext and synthqlQueryKey imports suggest a more modular and context-aware approach.


32-35: Query key construction simplified and modularized.

The use of synthqlQueryKey function for constructing the query key is a good improvement in terms of modularity. This change is consistent with the overall simplification of the useSynthql function.

Could you provide more information about the synthqlQueryKey function? Specifically:

  1. How does it generate the key?
  2. Does it play any role in the runtime type checking mentioned in the PR objectives?

Let's check the implementation of synthqlQueryKey:

#!/bin/bash
# Search for the implementation of synthqlQueryKey
rg --type typescript "export function synthqlQueryKey" -A 10

Line range hint 1-46: Overall: Good simplification, but clarification needed on runtime type checking.

The changes in this file consistently simplify type definitions and function signatures, which aligns with the goal of streamlining the code. However, there are a few points that need clarification:

  1. The PR objectives mention introducing runtime type checking, but this isn't immediately apparent in the changes. Could you explain how runtime type checking is implemented or where it fits into these changes?

  2. Some of the simplifications, particularly the use of any in type definitions, might reduce type safety. Is this intentional, and if so, how is type safety ensured?

  3. It would be helpful to have more context on how these changes fit into the larger picture of the SynthQL project and the runtime validation mentioned in the referenced blog post.

These clarifications would help in understanding the full impact and intention of these changes.

40-43: fetchJsonLines return type updated, but type safety concerns exist.

The update to fetchJsonLines to return QueryResult<any, TQuery> is consistent with the other changes in this PR. However, I have some concerns:

  1. The use of any might reduce type safety. Is there a way to make this more specific or to ensure type safety at runtime?
  2. How does this change relate to the introduction of runtime type checking mentioned in the PR objectives?

Let's check the implementation of fetchJsonLines to see if it includes any runtime type checking:

#!/bin/bash
# Search for the implementation of fetchJsonLines
rg --type typescript "export (async )?function fetchJsonLines" -A 15

8-11: Simplified type definition looks good, but needs clarification.

The simplification of SynthqlQueryOptions type aligns with the goal of streamlining type definitions. However, I have a couple of questions:

  1. How does this change impact type safety, given that it no longer enforces specific database or table types?
  2. How does this modification relate to the introduction of runtime type checking mentioned in the PR objectives?

To better understand the impact of these changes, let's check for any related type definitions or usages:

packages/backend/src/tests/propertyBased/properties/cardinalityMaybe.test.ts (2)

27-27: LGTM! Simplified type assertion improves code readability.

The removal of the explicit type assertion Query<DB> suggests that TypeScript can correctly infer the type of query. This change aligns with best practices for type inference and can lead to more maintainable code.

To ensure type safety is maintained, please verify that:

  1. The inferred type of typedQuery is still Query<DB>.
  2. All subsequent uses of typedQuery in the test case work as expected without type errors.

You can use the TypeScript compiler or your IDE's type checking features to confirm this.


Line range hint 46-58: Clarify the status of the skipped test case.

There's a skipped test case for invalid where queries. Given that this PR is introducing runtime type checking, it's important to understand the status of this test:

13-13: Approved, but clarification needed on the change rationale.

The modification to filmActor() function, changing from groupBy().columns() to columns().groupBy(), doesn't introduce functional issues as both versions effectively select all columns and apply the same grouping. However, I have a few points to consider:

  1. Could you please clarify the reason for this change? Understanding the motivation would help ensure it aligns with the project's goals.

  2. Consider the potential performance implications of this change. Depending on the query builder or ORM used, the order of operations might affect query optimization.

  3. Ensure this change is consistent with other query definitions in the codebase. If this is a pattern change, it might need to be applied consistently across other similar functions.

To check for consistency, let's examine other query definitions:

✅ Verification successful

Verified: No inconsistencies found in query definitions.

The updated filmActor() function reorders the method calls from groupBy().columns() to columns().groupBy(). After checking the codebase, no other query definitions use a different order, ensuring consistency across the codebase.

packages/queries/src/util/hashQuery.ts (2)

Line range hint 1-72: Summary and Recommendation

The changes in this file, particularly to the hashQuery function, align well with the PR objective of adding runtime type checking. The more restrictive type signature enhances type safety. However, there are a few points that need attention:

  1. The potential breaking change in the hashQuery function signature needs to be carefully considered and its impact on the existing codebase should be verified.
  2. The function body and comments should be updated to reflect the new signature.
  3. The use of external code and the choice of hashing algorithm should be reviewed for proper attribution and security considerations.

Overall, while the changes are moving in the right direction for improved type safety, I recommend addressing the raised issues before merging this PR. This will ensure better consistency, maintainability, and potentially prevent unexpected runtime behavior.

To ensure a comprehensive review, please run the following script to check for any other usages of AnyQuery type that might need updating:

#!/bin/bash
# Description: Check for other usages of AnyQuery type that might need updating

# Test: Search for AnyQuery usages
rg --type typescript '\bAnyQuery\b'

This will help identify if there are other places in the codebase that might need similar updates for consistency with the new approach to query typing.


9-9: ⚠️ Potential issue

Significant change in function signature - verify impact

The change from AnyQuery to Omit<Query, 'hash' | 'schema'> makes the function more restrictive and type-safe. This aligns well with the PR objective of adding runtime type checking. However, this change might have several implications:

  1. It could break existing code that relies on passing 'hash' or 'schema' properties.
  2. The function body doesn't reflect this change, potentially leading to unexpected behavior.

Please run the following script to check for potential breaking changes:

Consider updating the function body to explicitly ignore 'hash' and 'schema' properties if they are passed:

export function hashQuery(query: Omit<Query, 'hash' | 'schema'>): string {
    const { hash: _, schema: __, ...restQuery } = query as Query;
    return djb2Hash(
        JSON.stringify(restQuery, (_, val) => {
            // ... rest of the function remains the same
        }),
    );
}

This change ensures that the function behaves consistently with its new signature.

✅ Verification successful

Verification Successful: No Impact Found

The updated hashQuery function signature change to Omit<Query, 'hash' | 'schema'> does not affect any existing codebase usages. No instances of passing hash or schema properties to hashQuery were found.

packages/backend/src/tests/propertyBased/properties/cardinalityOne.test.ts (3)

3-3: LGTM: Import statement cleanup

The removal of the unused Query import from @synthql/queries is a good cleanup. This change aligns with the simplification of type assertions later in the file and doesn't appear to have any negative impact on the functionality.


55-55: LGTM: Consistent simplification of type assertions

The simplification of the typedQuery assignment here is consistent with the earlier change. This uniformity in approach is good for maintaining code consistency.

To ensure that all type simplifications in this file are working as expected, please run a comprehensive type check:

#!/bin/bash
# Description: Comprehensive type check for the entire file

# Test: Run TypeScript compiler in strict mode for the entire file
npx tsc --noEmit --strict packages/backend/src/tests/propertyBased/properties/cardinalityOne.test.ts

# Test: Use ast-grep to find any remaining explicit Query<DB> type assertions
ast-grep --lang typescript --pattern 'as Query<DB>' packages/backend/src/tests/propertyBased/properties/cardinalityOne.test.ts

The first command will catch any type inference issues, while the second command will help identify if there are any remaining explicit Query<DB> type assertions that might have been missed during the simplification process.


27-27: Verify type inference after simplification

The simplification of the typedQuery assignment by removing the explicit Query<DB> type assertion looks good. This change suggests a move towards more implicit typing, which can lead to cleaner code.

To ensure that type inference is still working correctly after this change, please run the following command:

If this command runs without any type errors, it confirms that the type inference is working as expected.

packages/backend/src/tests/propertyBased/properties/cardinalityMany.test.ts (4)

3-3: LGTM: Import statement reordering.

The reordering of the import statement for describe and expect from vitest is acceptable. This change doesn't affect functionality and may be due to code style preferences or automatic import sorting.


Line range hint 1-63: Overall, good use of property-based testing with minor improvements.

The use of property-based testing in this file is commendable and aligns well with the goal of adding runtime type checking. The changes made (import reordering and type assertion simplification) improve code quality without altering functionality.

Next steps:

  1. Verify that TypeScript correctly infers the type for typedQuery after removing the explicit type assertion.
  2. Consider enabling and updating the skipped test for invalid queries to ensure comprehensive coverage of the new runtime type checking functionality.
  3. If the skipped test cannot be enabled immediately, consider adding a TODO comment explaining why it's skipped and when it should be revisited.

These steps will help ensure that the new runtime type checking feature is thoroughly tested and that the test suite remains comprehensive and up-to-date.


54-54: Simplified type assertion looks good, but verify type inference.

The simplification of the type assertion for typedQuery is a good practice, letting TypeScript infer the type. This change aligns with the principle of relying on type inference when possible.

To ensure that TypeScript is correctly inferring the type, please run the following command:

If this command runs without any type errors, it confirms that TypeScript is correctly inferring the type of typedQuery.


Line range hint 50-63: Consider enabling the skipped test for invalid queries.

The test case for invalid queries is currently skipped. Given that this PR aims to add runtime type checking, it might be beneficial to enable and update this test to validate the new functionality.

To help assess the impact of enabling this test, please run the following command:

This will temporarily enable the skipped test and run it. The results will help determine if the test can be safely enabled or if it needs to be updated to work with the new runtime type checking functionality.

packages/backend/src/execution/executors/QueryProviderExecutor/convertWhereToQueryProviderInput.test.ts (2)

64-64: Approve consistent change, verify error case coverage

The removal of type parameters <DB, Table<DB>> from the convertWhereToQueryProviderInput function call in the error case tests is consistent with the earlier change and aligns with the PR objective of adding runtime type checking.

To ensure that the error cases still correctly test for unsupported where clauses, please run the following script:

#!/bin/bash
# Description: Verify that error cases still cover all unsupported where clauses

# Test: Extract and display all unsupported test cases
rg -A 1 'unsupportedCases:' packages/backend/src/execution/executors/QueryProviderExecutor/convertWhereToQueryProviderInput.test.ts

# Test: Verify that the error throwing test is still present and correctly implemented
rg -A 5 'should throw an error' packages/backend/src/execution/executors/QueryProviderExecutor/convertWhereToQueryProviderInput.test.ts

This script will display all unsupported test cases and the implementation of the error throwing test. Please review the output to confirm that:

  1. All necessary unsupported where clauses are still being tested.
  2. The error throwing test is correctly implemented without the type parameters.

If both conditions are met, it confirms that the error cases are still comprehensively covered despite the removal of explicit type parameters.


37-37: Approve simplification of function call, but verify type safety

The removal of type parameters <DB, Table<DB>> from the convertWhereToQueryProviderInput function call aligns with the PR objective of adding runtime type checking. This change simplifies the test code and improves readability.

To ensure this change doesn't compromise type safety, please run the following script:

This script will check if TypeScript compilation still succeeds and if the convertWhereToQueryProviderInput function is still properly typed. If both checks pass, it confirms that type safety is maintained despite the removal of explicit type parameters in the test file.

The reordering of import statements enhances code readability by grouping imports based on their source (built-in, third-party, local). This follows common best practices and improves maintainability.

packages/backend/src/tests/e2e/store-with-films.test.ts (3)

11-11: LGTM: Import statement reorganization.

The reorganization of the import statement for entities from 'queries.v2' is a minor change that doesn't affect functionality. It's a good practice to keep imports organized.


Line range hint 1-91: Overall feedback: Minor changes, but runtime type checking implementation not visible.

The changes in this file are minimal and don't directly implement the runtime type checking mentioned in the PR objective. While the modifications (import reorganization and simplified query execution) are improvements, they don't explicitly show how runtime type checking is being added to the project.

To align with the PR objective:

  1. Could you provide more context on how these changes relate to the runtime type checking feature?
  2. Are there other files where the core implementation of runtime type checking is located?
  3. Should this test file be updated to explicitly test the new runtime type checking functionality?

Let's check if there are other relevant files that might contain the runtime type checking implementation:

#!/bin/bash
# Description: Search for files that might contain runtime type checking implementation

# Test 1: Search for files with "runtime" and "type" in their name
fd -t f runtime.*type

# Test 2: Search for files with content related to runtime type checking
rg -l "runtime.*type.*check" --type ts

76-76: Simplified query execution looks good, but needs clarification.

packages/backend/src/execution/execute.test.ts (3)

Line range hint 220-225: LGTM! Verify type inference for execute function.

The removal of explicit type parameters <DbWithVirtualTables, typeof q> from the execute function call simplifies the code and aligns with the PR objective of adding runtime type checking. This change likely relies on type inference.

To ensure type safety is maintained, please verify that the types are correctly inferred by TypeScript. You can do this by hovering over the execute function in your IDE to check the inferred types, or by adding a type assertion and ensuring no type errors occur:

const result = await collectLast(
  execute(q, {
    executors: [new QueryProviderExecutor([actorProvider])],
    defaultSchema,
  }) as AsyncIterable<{ actor_id: number; first_name: string; last_name: string }>
);

If no type errors occur with this assertion, it confirms that type inference is working as expected.


Line range hint 250-258: LGTM! Ensure correct type inference for nested query structure.

The removal of explicit type parameters <DbWithVirtualTables, typeof q> from this execute function call is consistent with the previous change and aligns with the PR objective.

Given the complexity of the query structure with nested includes, it's crucial to verify that type inference works correctly for the entire result structure. Please confirm that the inferred type matches the expected structure:

type ExpectedResultType = {
  film_id: number;
  title: string;
  rating: {
    rating: string;
  };
};

const result = await collectLast(
  execute(q, {
    executors: [new QueryProviderExecutor([filmProvider, filmRatingProvider])],
    defaultSchema,
  }) as AsyncIterable<ExpectedResultType>
);

Ensure that this type assertion doesn't produce any type errors, confirming that the inferred types match the expected structure.


Line range hint 272-280: LGTM! Consistent application of type parameter removal.

The removal of explicit type parameters <DbWithVirtualTables, typeof q2> from this execute function call maintains consistency with the previous changes in this file.

This consistent application of the change across all execute calls in the file is commendable. It simplifies the code and aligns with the PR's objective of introducing runtime type checking.

💡 Codebase verification

Verified minimal external impact, but type safety concerns persist.

The useSynthql function is only used within packages/react/src/useSynthql.ts, so the changes do not affect other parts of the codebase. However, the use of any in the return type (QueryResult<any, TQuery>) still raises type safety concerns. Consider specifying a more precise type to enhance type safety.

🔗 Analysis chain

Function signature simplified, but type safety concerns exist.

The updated useSynthql function signature aligns well with the simplified SynthqlQueryOptions type. However, I have some concerns:

  1. The use of any in the return type (QueryResult<any, TQuery>) might reduce type safety. Is there a way to make this more specific?
  2. It's not clear how these changes support the introduction of runtime type checking mentioned in the PR objectives. Could you provide more context on how runtime type checking is implemented?

⚠️ Potential issue

Reconsider the use of any in the function signature

The changes to the execute function signature raise some concerns:

  1. The removal of the DB generic type parameter and the use of any in the return type (QueryResult<any, TQuery>) seem to contradict the PR objective of adding runtime type checking.
  2. Using any bypasses TypeScript's static type checking, which could lead to potential runtime errors and reduced type safety.

Consider the following alternatives:

  1. Keep the DB generic type parameter and use it in the return type.
  2. If the exact database type is not known at compile time, consider using unknown instead of any to maintain better type safety.
  3. If runtime type checking is being implemented elsewhere, ensure that it compensates for the loss of static type checking here.

Could you provide more context on why this change was made and how it aligns with the goal of adding runtime type checking?

⚠️ Potential issue

Reconsider the use of type assertion with any

The modification of the yield statement to include a type assertion as QueryResult<any, TQuery> raises similar concerns to those in the function signature:

  1. Using any in the type assertion bypasses TypeScript's type checking, which could potentially hide type errors.
  2. This change seems inconsistent with the goal of adding runtime type checking, as it reduces type safety at compile time.

Consider the following alternatives:

  1. If possible, avoid the type assertion altogether and let TypeScript infer the correct type.
  2. If a type assertion is necessary, consider using a more specific type than any for the database type.
  3. If runtime type checking is being implemented, ensure that it provides sufficient safeguards to compensate for the loss of static type checking.

Could you explain the reasoning behind this type assertion and how it fits into the overall strategy for runtime type checking?

⚠️ Potential issue

Optimize accumulator in reduce function to improve performance

Using the spread operator (...acc) inside the reduce function here can lead to O(n²) time complexity due to object spreading in each iteration. This may cause performance issues with larger datasets. Consider refactoring to enhance efficiency.

Apply this diff to fix the performance issue:

-return Object.entries(include)
-    .map(([key, value]) => {
-        return { [key]: value.schema };
-    })
-    .reduce((acc, curr) => ({ ...acc, ...curr }), {}) as any,
+const includeSchemas = {} as Record<string, TSchema>;
+for (const [key, value] of Object.entries(include)) {
+    includeSchemas[key] = value.schema;
+}

This change replaces the map and reduce chain with a simple for...of loop, which avoids the spread operator and improves performance by maintaining linear time complexity.

Line range hint 9-15: Good improvements to the Simplify type, with a minor suggestion.

The updated Simplify type addresses the concerns raised in the past review comment and improves type inference:

  1. It correctly handles arrays, simplifying their elements recursively.
  2. It adds special handling for Date objects, which is a good practice.
  3. The type now correctly simplifies nested structures while preserving array and date types.

However, to fully address the past comment and improve type inference for tuples, consider adding explicit tuple handling:

 type Simplify<T> =
-    T extends Array<infer U>
+    T extends (infer U)[]
         ? Simplify<U>[]
+        : T extends [any, ...any[]]
+          ? { [K in keyof T]: Simplify<T[K]> }
         : T extends Date
           ? T
           : T extends object
             ? { [K in keyof T]: Simplify<T[K]> }
             : T;

This change will ensure that tuples maintain their specific structure and length information during simplification.

packages/queries/src/types/AnyQuery.ts (1)

Line range hint 1-21: Summary of changes and suggested next steps

The changes in this file represent a significant shift in the type system:

  1. AnyTable has been simplified from Table<AnyDB> to string.
  2. AnyQuery has been simplified and deprecated in favor of using Query directly.

These changes could have far-reaching implications across the codebase, potentially affecting type safety and existing code. To ensure a smooth transition:

  1. Consider providing a detailed migration guide for users of the library.
  2. Update all relevant documentation to reflect these changes.
  3. If possible, implement a gradual migration strategy to allow users time to adapt to the new type system.
  4. Consider adding runtime type checks to compensate for the reduced static type safety, if not already implemented.

Given the significant nature of these changes, it might be beneficial to:

  1. Clearly communicate the rationale behind this architectural shift to all stakeholders.
  2. Consider providing a compatibility layer or helper functions to ease the transition for existing users.
  3. If not already planned, consider adding comprehensive integration tests to ensure that these type changes don't introduce unexpected behaviors in the system.
packages/queries/src/types/types.ts (2)

6-21: LGTM: Well-structured QuerySchema with a suggestion for readability.

The QuerySchema constant is well-defined using the @sinclair/typebox library, providing a robust and flexible structure for query definitions. The recursive approach for the include property is particularly noteworthy, allowing for nested queries.

Consider adding a type annotation to improve code readability:

-export const QuerySchema = t.Recursive((self) =>
+export const QuerySchema: t.TSchema = t.Recursive((self) =>

This change explicitly declares the type of QuerySchema, which can enhance code clarity and potentially assist with type inference in other parts of the codebase.


1-24: Excellent implementation of runtime type checking using schema-based approach.

The transition from a TypeScript type-based approach to a schema-based approach using @sinclair/typebox is well-executed. This change aligns perfectly with the PR objective of adding runtime type checking to the SynthQL project. The new implementation provides several benefits:

  1. Robust structure for query definitions through the QuerySchema constant.
  2. Runtime validation capabilities, enhancing the reliability of the code.
  3. Maintained backward compatibility with flexible type parameters.
  4. Improved type safety with the updated Query type.

These changes significantly enhance the SynthQL project by incorporating runtime type checking, which will improve the robustness and reliability of the code by ensuring that data types are validated during execution.

As the project moves forward with this new schema-based approach, consider the following recommendations:

  1. Ensure comprehensive documentation of the new QuerySchema structure and its usage.
  2. Update any existing tests to cover the new schema-based validation.
  3. Consider creating helper functions or utilities to assist users in constructing valid queries based on the new schema.
packages/backend/src/QueryEngine.ts (1)

152-154: LGTM with a suggestion: Simplified method signature, but consider adding return type.

The changes to the compile method signature are good:

  1. The new signature compile<T extends Query>(query: T) is simpler and more flexible.
  2. It aligns with the changes made to other methods in the class.

However, I suggest adding the return type annotation back for clarity and explicit type safety:

compile<T extends Query>(query: T): {
    sql: string;
    params: any[];
}

This will ensure that the return type is explicitly documented and checked by TypeScript.

packages/queries/src/query.ts (2)

33-46: LGTM: Enhanced build method with improved validation and identification

The build method now includes runtime validation, hash generation, and default naming, which enhance type safety and query identification.

Consider extracting the default name generation logic into a separate private method for better readability and maintainability. For example:

private getDefaultQueryName(built: Query<TResultSchema>): string {
    const whereColumns = Object.keys(built.where).slice(0, 2).join('-and-') || 'all';
    return `${built.from}-by-${whereColumns}`;
}

Then, you can use it in the build method:

built.name = built.name ?? this.getDefaultQueryName(built);

Line range hint 52-123: LGTM: Improved query building methods with better chaining support

The limit, take, and offset methods now return new QueryBuilder instances, allowing for method chaining. The separation of limit and take provides clarity in API usage.

For consistency, consider adding explicit return types to the limit and take methods, similar to the offset method. For example:

limit(limit: number): QueryBuilder<DB, TTable, TResultSchema> {
    // ... existing implementation
}

take(take: number): Query<TArray<TResultSchema>> {
    // ... existing implementation
}

This change would improve type safety and maintain consistency across these related methods.

packages/ui/src/components/Editor/types.json (1)

Line range hint 4-13: Consider documentation updates and migration guide

The extensive improvements to type definitions in both @synthql/backend and @synthql/queries modules are excellent and will enhance the overall type safety and expressiveness of the SynthQL query system. However, these changes may impact existing code that relies on the previous type definitions.

To ensure a smooth transition for users of the library:

  1. Consider updating the documentation to reflect these new type definitions and their usage.
  2. It may be helpful to create a migration guide for users to update their existing code to work with the new type system.
  3. If possible, add examples demonstrating the benefits of the new type system in common use cases.

These steps will help users understand and adopt the improvements more easily.

🔇 Additional comments (26)
packages/queries/src/types/QueryResult.ts (2)

1-1: LGTM: Import statement addition is appropriate.

The addition of the Static import from '@sinclair/typebox' is consistent with its usage in the updated QueryResult type definition.


4-7: Excellent simplification of the QueryResult type.

The updated QueryResult type is a significant improvement:

  1. It's more concise and easier to understand.
  2. It directly infers the result type from the Query type, which is more intuitive.
  3. The use of Static<TQueryResult> suggests better integration with the typebox library, aligning with the PR's objective of adding runtime type checking.

This change should make the type system more robust and easier to maintain.

packages/queries/src/types/AnyQuery.ts (2)

18-21: Deprecation of AnyQuery and type simplification

The changes to AnyQuery type and its deprecation notice are noted:

  1. The type has been simplified from Query<AnyDB, AnyTable> to Query.
  2. A deprecation notice has been added, suggesting users should use Query directly.

These changes align with the simplification of AnyTable and indicate a shift in the API. To ensure a smooth transition:

  1. Consider updating the documentation to reflect these changes and provide migration guidelines.
  2. It might be helpful to add a brief explanation of why AnyQuery is being deprecated and the benefits of using Query directly.

Could you provide more information on the migration plan? For example:

  • Is there a timeline for removing AnyQuery completely?
  • Are there any automated migration tools or codemods planned to help users update their code?

Let's check the usage of AnyQuery across the codebase to assess the impact:

#!/bin/bash
# Description: Check usage of AnyQuery type across the codebase
# Expected result: List of files and contexts where AnyQuery is used

echo "Files importing or using AnyQuery:"
rg --type typescript -A 3 "import.*AnyQuery|AnyQuery"

echo "\nFiles potentially affected by AnyQuery change:"
rg --type typescript -A 3 "Query<AnyDB, AnyTable>"

17-17: Significant change to AnyTable type - please clarify the rationale

The AnyTable type has been changed from Table<AnyDB> to string. This is a substantial modification that could have significant implications:

  1. It simplifies the type but potentially at the cost of type safety.
  2. It removes the dependency on the Table type and AnyDB.
  3. This change might break existing code that relies on the previous structure of AnyTable.
  4. It could lead to loss of type information and intellisense support in IDEs.

Could you please provide more context on why this change was made? Are there any plans to mitigate potential issues arising from this change?

To assess the impact, let's check the usage of AnyTable across the codebase:

1-4: LGTM: Import statements are appropriate for the new implementation.

The import statements have been updated to include the necessary types and functions from @sinclair/typebox, which are required for the new schema-based approach. The existing imports for CardinalitySchema, SelectSchema, and WhereSchema are still relevant and correctly maintained.


22-24: LGTM: Improved Query type with removed unused generics.

The updated Query type effectively combines the static type derived from QuerySchema with an optional schema property, providing both structure and flexibility. The use of TQueryResult extending TSchema allows for type-safe custom schema definitions.

As per the previous review comment, the unused generic type parameters DB and TTable have been removed, simplifying the type definition. This change has been correctly implemented in the new version.

packages/backend/src/query/iterateResultRow.test.ts (3)

1-1: LGTM: Import statement reorganization

The reorganization of import statements, moving QueryResult and col imports to the top, improves code readability and follows common import ordering conventions.


Line range hint 7-38: LGTM: Well-structured test case

The test case for iterateResultRows is well-structured and comprehensive:

  • It uses a realistic sample query result.
  • The use of Array.from and map effectively transforms the iterator results for assertion.
  • The expected output checks both column names and values, providing good coverage.

The overall logic of the test is sound and should effectively verify the behavior of the iterateResultRows function.


12-12: Verify consistency of QueryResult type usage

The simplification of the QueryResult type from QueryResult<DB, typeof q> to QueryResult<typeof q> looks good and aligns with the PR objective of adding runtime type checking. However, it's important to ensure this change is consistent across the codebase.

Please run the following script to check for any inconsistencies in QueryResult usage:

This will help identify any places where the old QueryResult<DB, ...> pattern might still be in use outside of test files.

✅ Verification successful

The QueryResult type signature change is consistent and maintains type safety.

All instances of QueryResult in the codebase have been updated to remove the DB type parameter, ensuring the change is applied consistently.

# Note: Manually review the test results to ensure all tests pass and there are no unexpected warnings or errors

10-10: Verify the impact of the simplified generic constraint

The function signature has been modified to use a more general constraint T extends Query instead of T extends Query<DB, TTable>. While this change increases flexibility by allowing a broader range of query types, it also reduces type specificity.

Please ensure that:

  1. All existing test cases still pass with this change.
  2. This modification aligns with the project's overall approach to type constraints.
  3. The queryEngine.execute method can handle this more general query type without issues.

To verify the impact of this change, please run the following script:

  2. Constraining TQuery to extend Query maintains type safety while allowing more flexibility.

This consistency in changes across methods is commendable and improves the overall API design.


166-166: LGTM: Broadened applicability of the explain method.

The changes to the explain method signature are beneficial:

  1. Accepting any Query type instead of a specific Query<DB, TTable> broadens the method's applicability.
  2. This change is consistent with the modifications made to other methods in the class.
  3. The implementation now uses SynthqlError for error handling, which explains the new import added earlier.

These changes improve the flexibility of the API while maintaining consistent error handling.

packages/queries/src/query.ts (5)

23-31: LGTM: Improved QueryBuilder class structure

The simplified class signature and constructor improve maintainability and type safety. The use of Partial<Query> allows for flexible query construction, while the TSchema parameter enables type-safe schema handling.


131-170: LGTM: Enhanced cardinality methods with improved type safety

The one, many, and maybe methods now return Query objects with specific cardinalities, improving type safety. Setting both limit and cardinality properties ensures consistent query behavior. The use of t.Array in the many method aligns well with the TypeBox schema.


316-367: LGTM: Improved type definitions for enhanced type safety

The query function now uses the SelectAllSchema type, which improves type inference for query results. The new type definitions (SchemaOf, Append, and AppendToSchema) enhance type safety and flexibility in schema composition.

These changes provide a solid foundation for type-safe query building and schema manipulation.


198-213: ⚠️ Potential issue

Optimize the columns method for better performance

The columns method now returns a QueryBuilder with a TPick type, which improves type safety for selected columns. However, the use of the spread operator in the reduce function can lead to performance issues for large arrays.

To address the performance concern, replace the reduce function with a simple loop:

const select = {} as SelectFromKeys;
for (const key of keys) {
    select[key] = true;
}

This change will maintain O(n) time complexity and avoid potential performance issues with large arrays.
