Etag support for Koa responses using etag.

> __Please use @koa/etag (v5+) instead. It is the same module, and this package will be deprecated in the next major release.__

Installation

``bash

npm

$ npm install koa-etag

yarn

$ yarn add koa-etag
`

Example

`js

const Koa = require('koa');
const etag = require('koa-etag');
const conditional = require('koa-conditional-get');
const compress = require('koa-compress');

const app = new Koa();

// must be used before conditional and etag
app.use(compress());

// etag works together with conditional-get
app.use(conditional());
app.use(etag());

app.use(function (ctx) {
ctx.body = 'Hello World';
});

app.listen(3000);

console.log('listening on port 3000');
