Universal JavaScript Module Generator

A Yeoman generator for creating universal JavaScript modules that work everywhere using ES2015, Babel, Webpack, Mocha, Chai, Sinon, Karma, Isparta, and ESLint

Features

1. ES2015 - Universal JavaScript Module Boilerplate (UJSM) uses Babel to transpile ES2015 source code. There are several reasons to use ES2015 alongside with transpilation (instead of plain Node >= 4):

• The transpiled code will work with legacy Node versions;
• Since we're going to run this module in the browsers, it will be necessary to provide cross-browser compatibility;
• Seamless migration after you decide to drop 0.x.x support;

1. ES2015 Tests - Mocha flag --compilers js:babel-core/register (it's already preconfigured in the npm npm run test-server script) allows to transpile Mocha tests written with ES2015 on the fly.
2. Universal Tests - UJSM uses Karma to make sure that code works in the browser. A npm script test-browser does the job. Feel free to run the same tests in both environments - it can be preconfigured by answering No on Would you like to keep your server/client tests separate? question during generator initialization.
3. UMD - Webpack is preconfigured to integrate the Universal Module Definition (UMD) API (which provides compatibility with the most popular script loaders) to the ouput script.
4. TDD - The package has a particular npm script npm run tdd (and npm run tdd-browser for the browser testing) to start a Mocha watch task that reruns tests on file changes.
5. Git Hooks - Every time before commiting, husky runs npm tasks conveniently configured in the package.json (in this case it automatically starting both test and build tasks). You can temporary disable this feature by adding --no-verify flag (i.e $ git commit -am "Beep bop" --no-verify). The list of all available hooks can be found here.

Installation

# Install Yeoman and the UJSM generator globally
$ npm install -g yo generator-universal-module

# Make a new folder & open it
$ mkdir my-shiny-module && cd $_

# Run the generator
$ yo universal-module

Workflow

• npm run build - Build task that generates both minified and non-minified scripts;
• npm run test-server - Run Mocha tests once;
• npm run test-browser - Run Mocha tests in the browser using Karma once;
• npm run test - Shortcut for npm run test-server && npm run test-browser;
• npm run tdd - Run Mocha tests & watch files for changes;
• npm run tdd-browser - Run Karma (w/ Mocha) tests & watch files for changes;
• npm run coverage - Run Isparta, a code coverage tool;
