How to build a production version of React without minification?

Question

Background

I\'ve been following more or less the official guide to setup a local dev environment with react and it seems to use create-react-app, whic

To change the webpack config and build scripts you have either to eject from create-react-app (i would not recommend this step, as it breaks future compatibility) or you can use tools like rewire to override some settings

Take a look at this https://github.com/timarney/react-app-rewired

I personally used just rewire

npm i rewire --save-dev

Here is a sample config i created for one of my projects in the past and it worked pretty good!

1. Create a build.js
2. Change your package.json so that it runs build.js

build.js

const rewire = require('rewire');
const defaults = rewire('react-scripts/scripts/build.js');
const config = defaults.__get__('config');

// Consolidate chunk files instead
config.optimization.splitChunks = {
  cacheGroups: {
    default: false,
  },
};
// Move runtime into bundle instead of separate file
config.optimization.runtimeChunk = false;

// JS
config.output.filename = '[name].js';
// CSS. "5" is MiniCssPlugin
config.plugins[5].options.filename = '[name].css';
config.plugins[5].options.publicPath = '../';

Then in my package.json i changed the npm script links like this (node build which will run the build.js script)

package.json

"scripts": {
    "start": "react-scripts start",
    "build": "node build && gulp",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },

So if you really want to eject from create-react-app, all you have to do is to run

npm run-script eject

Then you will get a new folder with all configs used by create-react-app

But as i said before, there is no reason why not to use rewire and just override the config instead of ejecting

if it helps, please don't forget to mark as answer Cheers and good success
