🚀 Feature Proposal

Expose fastify param createRequestLogMessage, which would allow customizing request param log message.

Motivation

Currently logic for request logging looks like this:

    if (disableRequestLogging === false) {
      childLogger.info({ req: request }, 'incoming request')
    }

It is not possible to customize it, which may sometimes be desireable.

Example

It would be great to be able to replace incoming request with a custom-built message. So something like

    if (disableRequestLogging === false) {
      childLogger.info({ req: request }, createRequestLogMessage(req))
    }

createRequestLogMessage would default to a function which returns 'incoming request'.

Full usage example:

  const app = fastify({
    createRequestLogMessage: (req) => { return `${req.id}: incoming request`
  })
