Zepto.js – a minimalist JavaScript library

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 Copy Chapter

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

# on Windows
c:\zepto> SET MODULES=zepto event data
c:\zepto> 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:

# one-time operation
$ npm install coffee-script --global

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

# on Windows
c:\zepto> SET MODULES=zepto event data
c:\zepto> coffee make dist

Write documentation Copy Section

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 Copy Section

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 Copy Section

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).
