Provide stats for routes using `require('node:perf_hooks')`, for **Fastify**.
## Install
```sh
npm i @fastify/routes-stats
```
## Example
```js
'use strict'
const Fastify = require('fastify')
const fastify = Fastify()
fastify.register(require('@fastify/routes-stats'), {
printInterval: 4000, // milliseconds
decoratorName: "performanceMarked", // decorator is set to true if a performance.mark was called for the request
})
fastify.get('/', function (request, reply) {
reply.send({ hello: 'world' })
})
fastify.get(
'/:param/dynamic-route-example',
{ config: { statsId: 'group-stats-together' } },
function (request, reply) {
reply.send({ hello: 'world' })
}
)
fastify.get('/__stats__', async function () {
// stats is added to the fastify instance
return this.stats()
})
fastify.listen({ port: 3000 })
```
```sh
$ curl -s localhost:3000/__stats__ | jsonlint
{
"GET": {
"/": {
"mean": 0.2406786,
"mode": 0.755647,
"median": 0.121999,
"max": 0.755647,
"min": 0.050214,
