Logging

The logger is currently set up to log with console.log. In a future release, you will be able to hook into Gofer Engine and define your custom logger.

Logger is part of the Context. This allows you to use the logger from within any flow that includes the context such as a filter or transformer.

There are 4 log levels:

• debug should be used for development, testing, and debugging purposes only
• info should be used for your information only
• warn should be used for warnings that should be fixed, but are not show stoppers
• error should be used for show-stopping errors

The logger is fairly simple to use as seen in this example of a filter step:

// example.som
gofer
  .listen('tcp', 'localhost', 5501)
  .filter((msg, context) => {
    const isFemale = msg.get('PID-8')==='F'
    const { messageId, logger } = context
    if (!isFemale) {
      context.logger(`Msg ${messageId} was not a Female`, 'info')
    }
    return isFemale
  })
  .run()
