Proposal to remove debug logger as the default log provider and use winston logger.

Core logger

  • Custom Formatter support
    • Logging in JSON
    • Eternal Log viewers
  • Customise transports
  • Log levels
  • Switch log levels with env variables

debug logger

  • Debug logger uses a global DEBUG env variable to define log level and it cannot be over ridden by the aio library.
  • The environment variable takes precedence over AIO_LOG_LEVEL
  • Logs from 3rd party dependencies will also be logged when using this env variable

Winston

  • Use winston as the only log provider
  • Expose more winston configs via the aio core logger
  • Dependency size

Other Loggers

Logger Package Size (Minified)
winston 136.9 kB
bunyan 15.7 kB
log4js 77.2 kB
pino 6.3 kB

Bunyan

  • API Similar to winston
  • Serializers can be complicated
  • Supports multiple streams
  • Child loggers
