Logger

The provided logger is a standardized interface that wraps the Node.js console object. By default it tries to emit pretty logs for human readability, but it can be augmented in a number of ways to alter behavior.

Features​

  • Pretty formatting with color-coded output
  • Structured logging with object support
  • Log level management with per-service overrides
  • AsyncLocalStorage (ALS) integration for request context tracking
  • Multiple output targets for external logging services
  • Performance timing integration
  • Context management for service identification

Quick Start​

export function MyService({ logger }: TServiceParams) {
  logger.info("Service started");
  logger.debug({ userId: 123 }, "Processing user request");
  logger.error("Something went wrong");
}
