fastify-server-timing

Server-Timing API for fastify.

Expose Server-Timing to communicate one or more metrics and descriptions for a given request-response cycle. It is used to surface any backend server timing metrics (e.g. database read/write, CPU time, file system access, etc.) in the developer tools in the user's browser or in the PerformanceServerTiming interface.

Installation

npm install fastify-server-timing

Usage

Register the plugin and if needed pass to it some custom options.

const fastify = require('fastify')()
 
// using the defaults
fastify.register(require('fastify-server-timing'))
 
// with custom options
fastify.register(require('fastify-server-timing'), { /* ... Options ... */ })
 
// use reply.addServerTiming to report a metric
fastify.get('/', (request, reply) => {
  reply.addServerTiming('cache', 23.2, 'Cache Read')
  return {}
})
