🌄 InspireScript webpack Configurations

current version Build Prettier managed by semantic release InspireScript made with love

This package creates the base webpack configuration for InspireScript projects. The exported function expects an options object with the build environment. An optional paths object can be used to customize build behavior.

Installation

npm i -D @inspire-script/webpack-configs

Usage

// webpack.config.js
const { resolve } = require('path')
const webpackConfigs = require('@inspire-script/webpack-configs')
 
module.exports = env => {
  const baseConfigs = webpackConfigs({
    env,
    paths: {
      // Explicitly set the context for resolving entry points and loaders
      context: resolve(__dirname),
    },
  })
 
  /*
   * Make any changes to the base webpack configs for your application, eg:
   * baseConfigs.module.rules.push({ custom loader... })
   */
 
  return baseConfigs
}

The environment variable should be declared in the webpack build script with --env, eg:

{
  "build": "NODE_ENV=production webpack --env=production"
}

Configuring

The base configurations generated by the package can be customized per project by passing a configuration object.

Configurations

// The top level overrides allow specifying the build env, dev server
// customizations and default path overrides
const configs = {
  env,
  devServer,
  paths,
}

Path overrides

const paths = {

Project structure

Build defaults use the following directory structure:

project
├─ / public
│  ├─  index.html
│  └─  favicon.ico
├─ / src
│  └─ / api
│  └─ / components
│  └─ / dux
│  └─ / lib
│  └─ / media
│  └─ / styles
│  └─  index.js
├─  .babelrc
└─  webpack.config.js

webpack Resolution

The build configures the following module resolutions for convenient shorthand imports of common project directories.

Module Usage
/src Allows relative imports from the src directory, useful for shared utilities
/src/styles Allows importing style variables directly from any SASS partial

Environment variables

The following environment variables are injected by the build:

Constant Usage
process.env.NODE_ENV Defaults to match NODE_ENV, used by Babili to strip code in prod builds
process.env.DEBUG Defaults to false, can be used for adding detailed logging in dev environment
process.env.PUBLIC_PATH Set to publicPath configuration, useful for importing media and configuring CDN paths

Testing

Development and testing of the repository use a Docker workflow to ensure that the generated configs work with the packages required and the minimum version of Node supported. The /test-app directory includes a complete test application.

Unit tests are run with Jest and use snapshots to validate the generated configs for development and production environments.

Process

  1. Start the docker container: npm run container
  2. After the image/container are created start the dev server: npm start
