Logging

Up supports structured logging in the form of JSON written to stdout. To make this process a bit cleaner, up.js provides a Logger as shown here:

const { Logger } = require('up')
const log = new Logger()

log.error('user login attempt failed', { user: 'tobi' })
log.info('user login', { user: 'tobi' })
log.info('user logout', { user: 'tobi' })

The following severity levels are available:

  • debug
  • info
  • warn
  • error
  • fatal
