Zepto.js – a minimalist JavaScript library

This is not just Zepto but also tracks a custom build of zepto, and also exports out Zepto

To make custom build

$ MODULES="zepto event ajax form ie data stack" coffee make dist

this includes some modules that are not included in normal zepto like data and stack.

Back to Zepto.js

Zepto is a minimalist JavaScript library for modern browsers with a largely jQuery-compatible API. If you use jQuery, you already know how to use Zepto.

See zeptojs.com for an extended introduction, downloads and documentation.

Building

The official site offers a download of the default distribution of Zepto. This is good for starting out. However, at some point you might want to add some optional modules and remove some of the default ones you don't need, to keep the size at a minimum. That's when you need to check out Zepto's source code and use the build commands.

You will need Node.js installed on your system.

$ npm install
$ npm run-script dist

# do a custom build
$ MODULES="zepto event data" npm run-script dist

The resulting files are:

1. dist/zepto.js
2. dist/zepto.min.js

If you install CoffeeScript globally, you can run make directly:

$ coffee make dist
$ MODULES="zepto event data ..." ./make dist

Zepto modules

Zepto modules are individual files in the "src/" directory.

Write documentation

Zepto docs are written in Markdown and live in the "gh-pages" branch. They are published on zeptojs.com.

You can use GitHub's web interface to make quick changes to documentation for specific Zepto features (example: ajaxSettings). This will submit a pull request to us that we can review.

Report a bug

1. Check if the bug is already fixed in the master branch since the last release.
2. Check existing issues. Open a new one, including exact browser & platform information. For better formatting of your report, see GitHub-flavored Markdown.

Running tests

You will need to install PhantomJS. On OS X, that's easy:

$ brew install phantomjs

To run the automated tests:

$ npm test

To run a test server, which you can hit with your browsers and devices:

$ npm start

Go to http://your-ip-address:3000/ on your browser and follow the instructions. For your convenience test failures and exceptions will be reported to the the console you started the test server in (as well as the browser console if available).
