Say there is an awesome library you found on npm that you want to use within your un-ejected create-react-app project, but unfortunately, it's published in ES6+ (since node_modules doesn't go through babel-loader), so you cannot really use it.
However, with react-app-rewired and this library, react-app-rewire-babel-loader, you can use that awesome library you've found.
See below for usage.
🚨 Not maintained for react-app-rewired v2.x.x+
I'm not maintaining this library for react-app-rewired v2.x.x+.
Instead, please consider using: https://github.com/arackaf/customize-cra
The following essentially emulates react-app-rewire-babel-loader which you can copy & paste into your override config file:
// NOTE as of customize-cra v0.2.11
const { babelInclude, getBabelLoader } = require("customize-cra");
const include = (config, ...includes) => {
return babelInclude(includes)(config);
};
const babelExclude = exclude => config => {
getBabelLoader(config).exclude = exclude;
return config;
};
const exclude = (config, ...excludes) => {
return babelExclude(excludes)(config);
};Install

module.exports = function override(config, env) {
