Rewire Your App

Tweak the create-react-app webpack config(s) without using 'eject' and without creating a fork of the react-scripts.

All the benefits of create-react-app without the limitations of "no config". You can add plugins, loaders whatever you need.

All you have to do is create your app using create-react-app and then rewire it.

⚠️ Please Note:

By doing this you're breaking the "guarantees" that CRA provides. That is to say you now "own" the configs. No support will be provided. Proceed with caution.

How to rewire your create-react-app project

1) Install react-app-rewired

$ npm install react-app-rewired --save-dev

2) Create a `config-overrides.js` file in the root directory

/* config-overrides.js */

module.exports = function override(config, env) {
  //do stuff with the webpack config...
  return config;
}

+-- your-project
|   +-- config-overrides.js
|   +-- node_modules
|   +-- package.json
|   +-- public
|   +-- README.md
|   +-- src

Note: You can use one of the default rewires (see the packages dir) or injectBabelPlugin

3) 'Flip' the existing calls to `react-scripts` in `npm` scripts

  /* package.json */

  "scripts": {
-   "start": "react-scripts start",
+   "start": "react-app-rewired start",
-   "build": "react-scripts build",
+   "build": "react-app-rewired build",
-   "test": "react-scripts test --env=jsdom",
+   "test": "react-app-rewired test --env=jsdom"
}

4) Start the Dev Server

$ npm start

5) Build your app

$ npm run build

Utilities (injectBabelPlugin)

Adding a Babel plugin can be done via the injectBabelPlugin(pluginName, config) function. You can also use the "rewire" packages from this repo or listed below to do common config modifications.

const rewireMobX = require('react-app-rewire-mobx');
const rewirePreact = require('react-app-rewire-preact');
const {injectBabelPlugin} = require('react-app-rewired');

/* config-overrides.js */
module.exports = function override(config, env) {
  // add a plugin
  config = injectBabelPlugin('emotion/babel',config)
  
  // use the Preact rewire
  if (env === "production") {
    console.log("⚡ Production build with Preact");
    config = rewirePreact(config, env);
  }
  
  // use the MobX rewire
  config = rewireMobX(config,env);
  
  return config;
}
