@flancer32/teq-web

Infrastructure web server and deterministic request pipeline for TeqFW packages.

@flancer32/teq-web is an infrastructural component of the Tequila Framework (TeqFW) platform.

The package provides a deterministic request lifecycle pipeline and a built-in Node.js web server that other TeqFW packages can use as the runtime environment for processing HTTP requests.

Within the TeqFW ecosystem, this package plays a role similar to how Express or Fastify are used in typical Node.js applications: it acts as the web runtime layer used by higher-level packages.

Unlike general-purpose web frameworks, this package focuses only on coordinating request lifecycle execution through a deterministic handler pipeline.

The package requires the dependency container @teqfw/di.

Overview

The package provides infrastructure for processing web requests inside a TeqFW application.

Core responsibilities:

• deterministic request lifecycle coordination
• ordered handler execution pipeline
• Node.js server integration (http, http2, https)
• handler registration metadata
• static file handler
• DTO factories and enums used by handler implementations

The package does not provide:

• routing frameworks
• controllers
• application architecture
• persistence
• session management
• business logic abstractions

Its sole responsibility is coordinating the lifecycle of a web request.

Role in the TeqFW Ecosystem

Layer	Responsibility
Application packages	business logic, handlers
@flancer32/teq-web	web server and request lifecycle pipeline
@teqfw/di	runtime dependency linking

TeqFW applications are composed of multiple packages that declare dependencies through the DI container.

@flancer32/teq-web provides the web runtime layer in which those packages handle incoming requests.

Request Lifecycle

Each request is processed through a fixed three-stage pipeline:

INIT → PROCESS → FINALIZE

Stage semantics:

Stage	Purpose
INIT	request preparation (logging, enrichment, guards)
PROCESS	request handling
FINALIZE	cleanup and post-processing

Processing stops when a PROCESS handler marks the request as completed.

If no handler handles the request, the system produces 404 Not Found.

Core Components

Pipeline Engine

The Pipeline Engine is the single lifecycle coordination authority.

Responsibilities:

• handler registration
• deterministic handler ordering
• request lifecycle execution
• request completion control
• runtime error handling

Handlers are ordered based on declarative metadata (before / after constraints).

Server

The built-in server connects the Node.js transport layer to the request pipeline.

Supported server types:

• http
• http2
• https

The server locks the handler pipeline before entering the execution phase.

Handlers

Handlers are independent modules participating in request processing.

Each handler provides registration metadata:

• unique handler name
• execution stage
• relative ordering constraints

Handlers do not coordinate with each other directly. Execution order is derived from metadata and is deterministic.

Example (TeqFW Style)

// App/Web/Handler/Hello.mjs

export const __deps__ = {
  dtoInfoFactory: "Fl32_Web_Back_Dto_Info__Factory$",
  STAGE: "Fl32_Web_Back_Enum_Stage$",
};

export default class App_Web_Handler_Hello {
  constructor({ dtoInfoFactory, STAGE }) {
    const info = dtoInfoFactory.create({
      name: "App_Web_Handler_Hello",
      stage: STAGE.PROCESS,
    });

    this.getRegistrationInfo = () => info;

    this.handle = async function (context) {
      const { response } = context;

      response.writeHead(200, { "Content-Type": "text/plain" });
      response.end("ok");

      context.complete();
    };
  }
}

// App/Web/Server/Start.mjs

export const __deps__ = {
  pipeline: "Fl32_Web_Back_PipelineEngine$",
  server: "Fl32_Web_Back_Server$",
  helloHandler: "App_Web_Handler_Hello$",
};

export default class App_Web_Server_Start {
  constructor({ pipeline, server, helloHandler }) {
    this.execute = async function () {
      pipeline.addHandler(helloHandler);

      await server.start({
        port: 3000,
        type: "http",
      });
    };
  }
}

Application entry point:

const app = await container.get("App_Web_Server_Start$");
await app.execute();

Designed for Development with LLM Agents

TeqFW is an architectural approach designed for software development in which LLM agents participate directly in the development process.

Traditional software architectures assume that all code is written and maintained by humans.

TeqFW assumes a different workflow:

• humans design the architecture and specifications
• LLM agents generate and maintain the implementation

To support this workflow, TeqFW structures applications so they are easier for automated agents to analyze and modify.

Key design principles include:

• explicit dependency contracts
• deterministic runtime linking
• predictable module structure
• namespace-based component addressing
• minimal hidden coupling between modules

This allows systems to be more reliably:

• analyzed
• generated
• refactored
• extended

by both human developers and AI agents.

Agent-Driven Implementation

TeqFW libraries are developed using Agent-Driven Software Management (ADSM), a methodology created by Alex Gusev.

The workflow is:

1. A human architect defines the product model and specifications
2. LLM agents (Codex) generate the implementation
3. The human architect reviews and integrates the generated code

This package is part of that experiment and demonstrates how human-designed architecture can be implemented by AI agents.

Agent Interface

This package includes agent interface documentation intended for LLM agents that use the library as a dependency.

These documents are distributed inside the package in:

./ai/

For a quick integration reference, see:

• ai/examples/minimal-server.md

They describe:

• runtime abstractions
• request lifecycle semantics
• handler contracts
• integration rules for TeqFW applications

Human developers typically read the README and source code, while LLM agents can rely on the documentation in ./ai/.

Installation

npm install @flancer32/teq-web

The package requires a configured @teqfw/di container.

Tequila Framework

@flancer32/teq-web is part of the Tequila Framework (TeqFW) ecosystem.

More information about the platform: https://teqfw.com/

TeqFW is an experimental platform exploring how software architecture changes when AI agents become active participants in the development process.

Key architectural ideas include:

• modular monolith architecture
• runtime dependency linking
• namespace-based component addressing
• pure JavaScript without compilation
• system structures optimized for collaboration with LLM agents
