CSS Modules Webpack Demo
A working demo of CSS Modules, using Webpack's css-loader in module mode.
Run the example
$ npm install
$ npm start & open http://localhost:8080npm modules required for CSS modules
In this project's package.json file you find a lot of npm modules for this demo application. Since not all of them are required for the actual CSS modules features,
we've created the following list to describe their purposes.
Required modules
The following modules are the only ones really needed to get started with CSS modules:
| Module | Description | |
|---|---|---|
| Webpack | Webpack (obviously...) | |
| webpack-dev-server | (Optional) Supports hotloading of changed files etc while developing | |
| style-loader and css-loader | style-loader and css-loader process your CSS files. css-loader is the loader that actual makes CSS modules work |
To make CSS modules work with Webpack you only have to include the modules mentioned above and add the following loader to your webpack.config.js file:
. . .
{
test: /\.css$/,
loader: 'style!css-loader?modules&importLoaders=1&localIdentName=[name]__[local]___[hash:base64:5]'
}
. . .Optional modules
The following modules control the actual CSS processing. They are not CSS modules specific and can be used with both "regular" CSS and CSS modules:
| Module | Description |
|---|---|
| postcss-loader | Allows execution of various CSS post processor in Webpack. Required for autoprefixer-core and postcss-color-rebeccapurple |
| autoprefixer-core | Add vendor-prefixes to your css code (according to the GitHub page it is deprecated and should be replaced by autoprefixer |
| postcss-color-rebeccapurple | Another CSS post processor. Only needed to support rebeccapurple color in CSS |
| extract-text-webpack-plugin | Writes the CSS code processed by Webpack into an own CSS-file and not into the generated bundle JavaScript file. |
