# koa-response-time

[![Greenkeeper badge](https://badges.greenkeeper.io/koajs/response-time.svg)](https://greenkeeper.io/)

 X-Response-Time middleware for [koa](https://github.com/koajs/koa).  Compatible with [request-received](https://github.com/cabinjs/request-received).

## Installation

```js

$ npm install koa-response-time

```

## Usage

  Basic usage:

```js

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`:

```js

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

```

## Note

  Best to `.use()` at the _top_ before any other middleware,

  to wrap all subsequent middleware.
