jesti

ES2015 boilerplate for creating libraries with Babel, Rollup and Jest

Features

• ES6 with Babel for ES6 and ES7
• Jest for unit tests
• Jasmine for behavior-driven javascript
• Rollup for bundling
• Eslint to maintain a consistent code style
• Unit tests written with ES2015 get transpiled on the fly
• Browser tests in the browser
• Node >= 5.x

Getting Started

Just clone the repo and install the necessary node modules.

$ git clone https://github.com/kflash/jesti.git jesti
$ cd jesti
$ npm install                   # Install Node modules listed in ./package.json
$ npm run build                 # Build a minified and a non-minified version of the library

Workflow

• npm run build - Build task that generate a minified and a non-minified script
• npm run build:prod - Build task that generate a production bundle
• npm run build:dev - Build task that generate a development bundle
• npm run build:es6 - Build task that generate and preserves ES6 imports and exports into a ES2015 development bundle
• npm run lint:source - Lint the source
• npm run lint:tests - Lint the unit tests
• npm run clean - Remove the coverage report - and the dist folder
• npm run test - Runs unit tests
• npm run coverage - Runs unit tests and outputs a coverage report
• npm run watch - Run all unit tests and watch files for changes
• npm run packages - List installed packages
• npm run package:purge - Remove all dependencies
• npm run package:reinstall - Reinstall all dependencies
• npm run package:check - shows a list over dependencies with a higher version number then the current one - if any
• npm run package:upgrade - Automaticly upgrade all devDependencies & dependencies, and update package.json
• npm run browser - runs browser unit tests in the browser. All of your unit tests get bundled automatically.

Testing environment

This project uses Jest to run your unit tests.

To add a unit test, simply create a .spec.browser.js inside the ~../__tests__/ folder. Jest will pick up on these files automatically.

To run the tests in the project, just simply npm run test for browser tests.

To keep watching the common test suites that you are working on, simply do npm run watch.

Package management

Boily has build-in some nice features to always make sure your dependency tree are up to date.

To check for the latest dependencies, simply run npm run package:check.

If you want to update your packages, you can simply do npm run package:upgrade.

Note! Your package.json will be automatically updated so make sure you have saved your changes before running this.

To reinstall all packages, do npm run package:reinstall, and to remove all packages npm run package:purge.

Linting

ESLint are used to lint your source. To change the rules, edit the .eslintrc file in the root directory, respectively.

Installation

Download the package, and run this from the command line:

npm install
