⚠️ STILL IN DEVELOPMENT

---

atomic-webpack-plugin

A webpack plugin for use with the intention to build the index file for components based on the Atomic Design methodology.

Why?

Originally started by the ARc template. Using the 'Dont worry' index file has some issues, esspecially if you are running in typescript. More info here

// https://github.com/diegohaz/arc/wiki/Atomic-Design#do-not-worry
const req = require.context(".", true, /\.\/[^/]+\/[^/]+\/index\.js$/);

req.keys().forEach((key) => {
  const componentName = key.replace(/^.+\/([^/]+)\/index\.js/, "$1");
  module.exports[componentName] = req(key).default;
});

Atomic Design should be a solution, not another problem. If you want to create a component and don't know where to put it (atoms, molecules, organisms etc.), do not worry, do not think too much, just put it anywhere. After you realize what it is, just move the component folder to the right place. Everything else should work. source

The solution is to leverage the building process that most projects already use. atomic-webpack-plugin wa born.

Getting Started

To begin, you'll need to install atomic-webpack-plugin:

npm install atomic-webpack-plugin--save-dev

or

yarn add -D atomic-webpack-plugin

Then add the plugin to your webpack config. For example:

webpack.config.js

const AtomicPlugin = require("atomic-webpack-plugin");

module.exports = {
  plugins: [
    new AtomicPlugin({
      base: "./app/components",
      regularExpression: /\.?\/.+\/index\.tsx$/,
    }),
  ],
};

Setup

You will need to add the aliases to get the intended module import style.

Example

import { Button } from "components";

tsconfig.json

{
  "compilerOptions": {
    "paths": {
      "components": ["./app/components"]
    }
  }
}

webpack.config.jj

const AtomicPlugin = require("atomic-webpack-plugin");

module.exports = {
  plugins: [
    new AtomicPlugin({
      base: "./app/components",
      regularExpression: /\.?\/.+\/index\.tsx$/,
    }),
  ],
  resolve: {
    modules: ["./app/components"],
    alias: {
      components: path.resolve(__dirname, "app/components"),
    },
  },
};

Folder structure

src/
  components/
    atoms/
      Button/
        index.tsx
        text.spec.ts
        index.stories.ts
    molecules/
    organisms/
    pages/
      LandingPage/
        index.tsx
        text.spec.ts
        index.stories.ts
    templates/
      layouts/
      containers/
      menus/
      transitions/

Options

Prop	Default	Description
base (string)	./src/components	The folder location of your components folder
output (string)	index.ts	The filename that will be generated at base
header (string)	// @generated\n// This file is automatically generated and should not be edited.\n\n	The test at the top of the output file
regularExpression (regularExpression)	/\.?\/.+\/index\.tsx$/	The expression used to find the files of the components. If you are using foldered components like Atom/Button/index.tsx then the default will work for you.
