Text Compression (Server)

Text compression minifies and zips files on build or on client side rendering of your web page. Using this on your deployed webpage can save significant time in page downloads and lead to better user retention.


To accomplish client-side rendering, you will need to implement the compression on the building of your pages (in this case, using Webpack) as well as on your server (Express). This example is for a React project using Webpack and Express.


First, install compression-webpack-plugin and add it to your webpack.config.js file:

module.exports = {
  plugins: [
    new CompressionPlugin({
      algorithm: 'gzip',
      test: /\.(js|css)$/i,

This will use GZIP to compress all JS and CSS files in your project.


Similar to Express's app.use(express.static(...)), this will allow Express to serve the GZIP files to the user. You need to install express-static-gzip and then add this to your server JS file:

var express = require("express");
var expressStaticGzip = require("express-static-gzip");
var app = express();

app.use("/", expressStaticGzip("/my/rootFolder/"));

On Your Server

On your server, add/merge your new code, npm i all the new dependencies, restart any PM2 instances and NGINX, and away you go!
