react-app-rewire-css-modules-extensionless

Adds CSS modules for CRA apps without requiring the .modules.css extension, using react-app-rewired.

This rewire is similar to react-app-rewire-css-modules with two differences:

Doesn't require .modules.css extension for CSS files in src/ the source folder.
Doesn't force you to install and use the sass-loader
Setups jest

Installation

$ npm install --save-dev react-app-rewire-css-modules-extensionless

Usage

In the config-overrides.js you created for react-app-rewired add this code:

module.exports = {
    webpack: (config, env) => {
        config = require('react-app-rewire-css-modules-extensionless').webpack(config, env, { /* options */ });
        // The line below is equivalent
        // config = require('react-app-rewire-css-modules-extensionless')(config, env, { /* options */ });

        // You may apply other rewires as well

        return config;
    },
    jest: (config) => {
        config = require('react-app-rewire-css-modules-extensionless').jest(config);

        // You may apply other rewires as well

        return config;
    },
};

If you are using the compose utility of react-app-rewired:

const { compose } = require('react-app-rewired');

module.exports = {
    webpack: compose(
        require('react-app-rewire-css-modules-extensionless').webpack({ /* options */ })
        // The line below is equivalent
        require('react-app-rewire-css-modules-extensionless')({ /* options */ })
        // ... other rewires
    ),
    jest: compose(
        require('react-app-rewire-css-modules-extensionless').jest()
        // ... other rewires
    ),
};

Available options:

Name	Description	Type	Default
test	The loader test pattern	string/RegExp	`/\.css$/`
include	The loader include condition	string/Array/RegExp/Function	src folder
exclude	The loader exclude condition	string/Array/RegExp/Function
localIdentName	The localIdentName option to pass to the `css-loader`	string	`[hash:base64:5]!` for production, `[name]__[local]___[hash:base64:5]!` otherwise

If you modify include and exclude to point to packages in node_modules, it's advised to use fs.realpathSync so that it plays well with packages linked with npm link. Alternatively, you may disable resolve.symlinks in your webpack configuration.
