@mck-p/logger

Overview

This package is a wrapper around logging that offers a uniform interface for all @mck-p services.

Usage

const createLogger = require("@mck-p/logger");

const logger = createLogger({
  name: "SERVICE_NAME" /* defaults to process.env.SERVICE_NAME */,
  level: "trace" /* defaults to process.env.LOG_LEVEL */
  serializers: {}, /* defaults to bunyan.stdSerializers */
  /* any other bunyan options will be copied over */
});

logger.trace("Some event happened.")

logger.warn(error, "Some Error happened.")

logger.fatal(error, "We are exiting one after a fatal error!")

Levels

• fatal (60): The service/app is going to stop or become unusable now. An operator should definitely look into this soon.
• error (50): Fatal for a particular request, but the service/app continues servicing other requests. An operator should look at this soon(ish).
• warn (40): A note on something that should probably be looked at by an operator eventually.
• info (30): Detail on regular operation.
• debug (20): Anything else, i.e. too verbose to be included in info level.
• trace (10): Logging from external libraries used by your app or very detailed application logging.
