Working with the project

MoJS uses Webpack and Babel for building, Karma for testing and Github Actions for the CI workflow.

Most of the core files are written in CoffeeScript, but the plan is to convert to TypeScript in the future.

Setup

Make sure your environment well fit the package.json engines field, which is, at the time of writing, aligned with NodeJS 20 and NPM 9.

Run npm install to get all dependencies and build tools to get ready!

Scripts

npm run dev - Start a webpack-dev-server and allow you to develop new features by seeing them live in your browser. Source map is also enabled to allow easy bug fixes in development.
npm run lint - Run eslint to lint the code and prevent syntax errors when implementing new code.
npm run test - Run all tests by creating a production-ready file, looking for Karma tests in the spec folder, and checking them against the dist/mo.umd.js file. Make sure to write new tests for all new code.
npm run build - Build a production-ready mo.umd.js file with webpack and put it in the dist folder.

Workflow

The Continuous Integration workflow uses BrowserStack to run Karma tests against a bunch of selected browsers for compatibility reasons. When running tests locally, Headless Chrome will be used as default browser.

Thanks for reading and happy contributing! 🎉 👍
