A simple guide to setup Atomizer with webpack.

Install the package

We offer two options for integrating with webpack, a loader and a plugin.


webpack-atomizer-loader is a webpack loader that can parse your source code for Atomizer classes and generate a CSS file.

First install the loader in your project.

npm i webpack-atomizer-loader -D

Then configure your webpack.config.js file like so.

import { resolve } from 'path';
import autoprefixer from 'autoprefixer';

export default {
    // ...
    module: {
        rules: [
                test: /\.html$/,
                use: [
                        loader: 'webpack-atomizer-loader',
                        options: {
                            configPath: resolve('./atomCssConfig.js'),
                            minimize: true,
                            postcssPlugins: [autoprefixer],

You can fine more detailed configuration information is available in the project repository.


Leverage our atomizer-plugins package to integrate our webpack plugin in your project.

First install the dependency in your project.

npm i atomizer-plugins -D

Then configure your webpack.config.js file like so.

import { webpack } from 'atomizer-plugins';

const atomizer = webpack({
    /* options */
    config: atomizerConfig,
    outfile: 'dist/atomizer.css',

export default {
    // ... webpack config
    plugins: [atomizer],

Configuration information and examples are available in the atomizer-plugins repository.

Start your build process

Run your build setup as configured in your project’s package.json.

npm run dev
