Enable Gzip Mode for Express, Egg.js, Koa.js

0
Node.js

To reduce download size of APIs and static files, we can enable Gzip when server resources are sufficient.

Express

Express version below 4.0

var express = require('express');
var app = express();
app.use(express.compress()); //Mainly this line

Express version 4.0 and above (including 4.0)

var compression = require('compression');
var express = require('express');
var app = express();
app.use(compression());

Egg.js

// app/middleware/compress.js
// koa-compress exposed interface (`(options) => middleware`) matches framework's middleware requirements
module.exports = require('koa-compress')

// config/config.default.js
module.exports = {
  middleware: [ 'compress' ],
  compress: {
    threshold: 2048,
  },
};

Koa.js

const koa = require('koa');
const compress = require('koa-compress');

const app = koa();

const options = { threshold: 2048 };
app.use(compress(options));
