@pirxpilot/server-timings

This is a modernized fork of server-timings

Usage

Load the middleware as early as possible to record the request timing:

import express from 'express';
import timings from 'server-timings';
import routes from './routes.js';

const app = express();

app.use(timings);
app.use(routes);

This will automatically add a Server-Timing header shown in milliseconds.

$ curl https://jsonbin.org/remy/urls -I
HTTP/1.1 200 OK
Content-Type: application/json; charset=utf-8
Server-Timing: total; dur=72.45

To include additional timings the middleware exposes two methods on the res.locals.timings property:

• start(label[, description]) - record the start time
• end(label) - end the record time - if this isn't called, it will be called when the request is finished

Start/end as middleware

As well as being exposed in res.locals.timings you can also call start and end as middleware:

import timings from 'server-timings';
import routes from './routes.js';

app.use(timings);
app.use(timings.start('routing'));
app.use(routes);
app.use(timings.end('routing'));
