Morgan is HTTP request logger middleware for Node.js, commonly used with Express. It supports predefined and custom log formats, configurable output streams, and request/response filtering options.

Use cases

• log http requests in express
• access log middleware for node.js
• log only error responses
• custom http log format
• write request logs to a file
• structured logging of http requests

When to choose

• you use Express or Connect and need request logging middleware
• you want simple, configurable access logs with predefined formats like combined or tiny
• you need to route logs to a custom stream or structured logger

When to avoid

• you need a full application-level logging library with levels and transports (use winston or pino)
• you are not running a Node.js HTTP server
• you need distributed tracing rather than request logs
