Contribution Guide:

Quickstart

• clone this repo locally
• run npm install & npm run build
• Include the /packages/alpinejs/dist/cdn.js file from a <script> tag on a webpage and you’re good to go!

Brief Tour

You can get everything installed with: npm install in the root directory of this repo after cloning it locally.

This repo is a “mono-repo” using npm workspaces for managing the packages. Each package has its own folder in the /packages directory.

Rather than having to run separate builds for each package, all package bundles are handled with the same command: npm run build

Here’s a brief look at each package in this repo:

Package	Description
alpinejs	The main Alpine repo with all of Alpine’s core
collapse	A plugin for expanding and collapsing elements using smooth animations
csp	A repo to provide a “CSP safe” build of Alpine
docs	The Alpine documentation
focus	A plugin that allows you to manage focus inside an element
history	A plugin for binding data to query string parameters using the history API (name is likely to change)
intersect	A plugin for triggering JS expressions based on elements intersecting with the viewport
mask	A plugin for automatically formatting a text input field as a user types
morph	A plugin for morphing HTML (like morphdom) inside the page intelligently
persist	A plugin for persisting Alpine state across page loads

The compiled JS files (as a result of running npm run [build/watch]) to be included as a <script> tag for example are stored in each package’s packages/[package]/dist directory.

Each package should at least have: a “cdn” build that is self-initializing and can be included using the src attribute in a <script defer> tag, and a module.[esm/cjs].js file that is used for importing as a JS module (cjs for node, esm for everything else).

The bundling for Alpine V3 is handled exclusively by ESBuild. All of the configuration for these builds is stored in the scripts/build.js file.

Testing

There are 2 different testing tools used in this repo: Cypress (for integration tests), and Vitest (for unit tests).

All tests are stored inside the /tests folder under /tests/cypress and /tests/vitest.

If you wish to only run Cypress and open it’s user interface (recommended during development), you can run: npm run cypress

If you wish to only run Vitest tests, you can run npm run vitest like normal and target specific tests.
