Encryption

Set the APPLY_ENCRYPTION environment variable to true to enable encryption.

Global Environment Object

You can directly access the environment attributes in any component/file using global environment object. For more details please check file src/global.ts.

Example

To access the applyEncryption attribute from Envionment class to Response Handler, write environment.applyEncryption;

Default System Health Status API

• ${host}/api/status/system - Return the system information in response
• ${host}/api/status/time - Return the current time in response
• ${host}/api/status/usage - Return the process and system memory usage in response
• ${host}/api/status/process - Return the process details in response
• ${host}/api/status/error - Return the error generated object in response

Notes

1. Why is my git pre-commit hook not executable by default?

• Because files are not executable by default; they must be set to be executable.

chmod ug+x .husky/*
chmod ug+x .git/hooks/*

2. Production Best Practices: Security

• Don’t use deprecated or vulnerable versions of Express
• Use TLS
• Use Helmet
• Use cookies securely
• Prevent brute-force attacks against authorization
• Ensure your dependencies are secure
• Avoid other known vulnerabilities
• Additional considerations
