Quick start

npm i -g webpack-wizard
cd /my-projects
webpack-wizard boil # you will be asked some questions about your new project
cd my-new-project
npm start

# now you have all the goodness of latest webpack, babel, react-hot-loader, scss,
# react, react-router, redux, redux-saga reselect, re-reselect etc. without any configuration

Description

Webpack Wizard is an opinionated build process tool, that is meant to:

• be a facade for your build process dependencies
  • you can get rid of most of your devDependencies, because webpack-wizard handles these things for you
• be a facade for webpack config by providing the defaults for:
  • HMR
  • Babel (with JSX)
  • SCSS
  • CSS modules
  • EJS templates
  • Autoprefixer

All you have to do after installing is one of the following:

• set NODE_ENV env variable to production or development
• create webpack-wizard.config.js file with isDev && isProd options (see "Config" section below)

Bring your own libraries or check out the boilerplates.

Usage

Install

npm install webpack-wizard --save-dev

Configure or... not

Webpack Wizard comes with defaults. You do not need a config. But you can create webpack-wizard.config.js in root directory of your project. This file will be transformed into webpack config on the fly. You can see the documentation for the config below.

Project structure for the default config

- dist/ # generated when running `webpack-wizard build`
  - bundle.js
  - index.html
  - styles.css
- node_modules/
- src/
  - styles/
    - globals.scss
  - index.js
  - index-dev.js
- favicon.ico
- index.html

Add npm scripts

It's recommended to use webpack-wizard build & webpack-wizard start scripts in package.json with better-npm-run (npm install better-npm-run --save-dev), so that you can easily (and cross-platform) provide appropriate NODE_ENV env variable.

...
"scripts": {
  "build": "better-npm-run build",
  "start": "better-npm-run start"
},
"betterScripts": {
  "build": {
    "command": "webpack-wizard build",
    "env": {
      "NODE_ENV": "production"
    }
  },
  "start": {
    "command": "webpack-wizard start",
    "env": {
      "NODE_ENV": "development"
    }
  }
},
...

Development server

Run webpack-wizard start in root directory of your project to start a development server.

Production build

Run webpack-wizard build in root directory of your project to start production build.

Config

webpack.wizard.config.js should be a JavaScript module that exports either:

• a Webpack Wizard config object
• or a function that returns either
  • a Webpack Wizard config object
  • or a webpack config

If you'll go with the function, it will be invoked with 2 arguments: 1. webpackWizard - function that accepts a Webpack Wizard config object and returns a webpack config object 2. utils - see src/utils.js to see what utils are available (resolveCwdPath will be most useful)

All paths you provide should be absolute, except for stylesGlobals option. All default paths are relative to your current working directory.

Webpack Wizard config object

input

input should be an Object with the following attributes:

output

output should be an Object with the following attributes:

Complete example

module.exports = (webpackWizard, { resolveCwdPath }) => ({
  isDev: process.env.NODE_ENV === 'development',
  isProd: process.env.NODE_ENV === 'production',
  devHost: 'localhost',
  devPort: 8080,
  env: {
    API_HOST: JSON.stringify(process.env.API_HOST),
    API_PORT: JSON.stringify(process.env.API_PORT),
    NODE_ENV: JSON.stringify(process.env.NODE_ENV)
  },
  input: {
    favicon: resolveCwdPath('html/favicon.ico'),
    html: resolveCwdPath('html/index.html'),
    js: resolveCwdPath('src/index.js'),
    jsDev: resolveCwdPath('src/index-dev.js'),
    modules: [
      resolveCwdPath('src')
    ],
    styles: [
      resolveCwdPath('src/styles')
    ],
    stylesGlobals: 'globals.scss'
  },
  output: {
    directory: resolveCwdPath('dist'),
    css: 'styles.css',
    html: 'index.html',
    js: 'bundle.js'
  }
});

Which (because of the defaults) would have much shorter equivalent:

module.exports = (webpackWizard, { resolveCwdPath }) => ({
  devPort: 8080,
  input: {
    favicon: resolveCwdPath('html/favicon.ico'),
    html: resolveCwdPath('html/index.html')
  }
});

Customization

If you need to access/modify webpack config generated from your webpack-wizard.config.js you can modify webpack-wizard.config.js in the following way:

module.exports = (webpackWizard) => {
  const webpackWizardConfig = { /* ... */ };
  const webpackConfig = webpackWizard(webpackWizardConfig);
  /* now do stuff to webpackConfig */
  /* for example */ webpackConfig.target = 'electron-main';
  return webpackConfig;
};

or this way, if you prefer an explicit webpack-wizard dependency:

const webpackWizard = require('webpack-wizard');
const webpackWizardConfig = { /* ... */ };
const webpackConfig = webpackWizard(webpackWizardConfig);
/* now do stuff to webpackConfig */
/* for example */ webpackConfig.target = 'electron-main';
module.exports = webpackConfig;

Boilerplates

Webpack Wizard has one experimental built-in boilerplate: react-redux. You can use it in the following way:

npm install -g webpack-wizard    # installs webpack-wizard command globally (you only need to do this once)
cd /my-projects                  # go to a directory, which you want to become a parent directory for your new project
webpack-wizard boil              # run webpack-wizard boilerplate generator - you will be asked some questions about your new project

# when you answer the questions, npm install will be executed (among other things), so this will take a while

cd my-project                    # open freshly created directory
npm start                        # you're good to go, you can run your development server
npm run build                    # or production build
npm run start:prod               # and then serve it with simple http server
