Logging

[MuhammadKhalilzadeh]

Logging is essential for monitoring, debugging, and auditing your application. It should be structured and consistent.

Things we need to consider:

• - Log Levels: Use appropriate log levels (e.g., info, warn, error, debug).
• - Structured Logging: Use JSON or key-value pairs for logs to make them easier to query and analyze.
• - Log Storage: Decide where to store logs (e.g., files, databases, etc.)
• - Performance: Ensure logging does not become a bottleneck.

Implementation in Clean Architecture:

• Infrastructure Layer:

• Implement logging libraries (we need to find the best library in Node.js).

• Configure log storage (e.g., PostgreSQL table, file system, or external service).

• Application Layer:

• Log important business events, errors, and warnings.

• Presentation Layer:

• Log API requests, responses, and errors.
