Webpack Config

A shareable webpack configuration with sensible defaults and extensible configs for assets.

Inspired by configuration practices found on survivejs.com.

Install

yarn add -D webpack webpack-merge webpack-cli @waldronmatt/webpack-config

Usage

package.json

"scripts": {
  "dev": "webpack --env development --config webpack.dev.js",
  "build": "webpack --env production --config webpack.prod.js"
}

webpack.dev.js

const { extendWebpackBaseConfig } = require('@waldronmatt/webpack-config');
const commonConfig = require('./webpack.common.js');

const developmentConfig = {
  // dev configs
};

module.exports = extendWebpackBaseConfig(commonConfig, developmentConfig);

webpack.prod.js

const { extendWebpackBaseConfig } = require('@waldronmatt/webpack-config');
const commonConfig = require('./webpack.common.js');

const productionConfig = {
  // prod configs
};

module.exports = extendWebpackBaseConfig(commonConfig, productionConfig);

webpack.common.js

• Use isProduction to apply configs based on the environment.
• Access Webpack's env variable.
• Apply extensible base configs from @waldronmatt/webpack-config.
• Include your own extensible configs using your own parts via const parts = require('./webpack.parts.js');.
• Configs you set will take precedence if they overlap with @waldronmatt/webpack-config.

const { merge } = require('webpack-merge');
const { baseParts } = require('@waldronmatt/webpack-config');
const parts = require('./webpack.parts.js');

const commonConfig = (isProduction, env) => {
  // pass `isProduction` and Webpack's `env` variable into your parts file
  parts(isProduction, env);

  return merge([
    {
      entry: {
        main: './src/index.js',
      },
    },
    baseParts.loadJS({}),
    baseParts.setScriptOutputPath({}),
    baseParts.loadCSS({}),
    baseParts.setStyleOutputPath({}),
    // custom configs from your own `parts` file
    parts.loadHTMLPages({
      title: 'about',
    }),
  ]);
};

module.exports = commonConfig;

webpack.parts.js

Optionally set up your custom config parts to include in webpack.common.js.

const { MiniHtmlWebpackPlugin } = require('mini-html-webpack-plugin');

const parts = (isProduction, env) => {
  module.exports.loadHTMLPages = ({ title } = { title: 'MySite' }) => ({
    plugins: [
      new MiniHtmlWebpackPlugin({
        context: { title },
        publicPath: isProduction ? 'mydomain' : '/',
      }),
    ],
  });
};

module.exports = parts;

Options

You can load optional configs from this package into your own:

webpack.common.js

const { baseParts } = require('@waldronmatt/webpack-config');

• baseParts.loadCSS({})
• baseParts.loadSCSS({})
• baseParts.setStyleOutputPath({})
• baseParts.loadSourceMaps({})
• baseParts.loadJS({})
• baseParts.enableTypeChecking({})
• baseParts.setScriptOutputPath({})
• baseParts.loadImagesAsFiles({})
• baseParts.loadImagesAsFilesOrInline({})
