Interface LoggerOptions

OptionalonLog

• onLog?(...args: any[]): void

  Receives log lines. The default transport writes the log line to process.stderr, console.debug or console.log depending on what is available in the environment.

  The args are not formatted - they can be passed to util.format from Node.js or to format exported from this module as weald/format.

  Parameters

  • ...args: any[]

  Returns void

  Example: Receiving log lines

  import debug from 'weald'
  import { format } from 'weald/format'
  
  const logger = debug('my-namespace', {
    onLog (...args: any[]) {
      const line = format(...args)
      // do something with `line`
    }
  })
