logging-best-practices

Structured logging in Next.js API routes is standardized by importing a centralized Pino logger and passing a context object first, then a message string. You use specific log levels like trace, debug, info, warn, error, and fatal to improve observability across development, staging, and production environments.

The best way to pass context and errors to Pino logs is using a context-first signature: provide a context object as the first argument and the message second. Attach errors within that context object using the err property to ensure proper structured output for debugging.

You cannot directly import Node modules inside Next.js workflows. To use logging safely within workflows, wrap your logging calls inside a 'use step' function so the runtime can securely execute the logging logic without direct Node module imports.

Yes, this structured logging approach works across development, staging, and production environments. It applies standardized Pino logging with context-first signatures and specific log levels to server API routes and workflow steps throughout your entire Next.js application lifecycle.

You use a centralized logger for Node.js observability to standardize structured logs with Pino across all routes, libraries, and workflows. This enforces consistent context-first log signatures and specific levels, significantly improving debugging and application monitoring.
