koa-response-time

X-Response-Time middleware for koa. Compatible with request-received.

$ npm install koa-response-time

Basic usage:

const Koa = require('koa');
const responseTime = require('koa-response-time');
const app = new Koa();

app.use(responseTime());

If you need response high resolution in nano time, set hrtime option to true:

app.use(responseTime({ hrtime: true }));

Sample response header with hrtime = false (default):

X-Response-Time: 153ms

Sample response header with hrtime = true:

X-Response-Time: 153.123581ms

Best to .use() at the top before any other middleware, to wrap all subsequent middleware.
