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.

Zepto.js is licensed under the terms of the MIT License.

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 minimum. That's when you need to check out Zepto's source code and use the build commands.

You will need ruby, RubyGems, and rake installed on your system.

# dependencies:
$ ruby -v
$ gem -v
$ rake -V

# required to generate the minified version:
$ gem install uglifier

Build Zepto by running rake:

$ rake
Original version: 40.423k
Minified: 18.776k
Minified and gzipped: 7.033k, compression factor 5.747

The resulting files are:

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

To include optional modules and remove default ones, use the concat task. In this example, "fx" is removed, but "data" and "selector" are added:

$ rake concat[-fx:data:selector] dist

Zepto modules

Zepto modules are individual files in the "src/" directory. You can also list the available modules by running rake modules.

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

Zepto test suite is in "test/*.html" files. Open the individual files in a web browser to run the tests. Files named with "_functional" are not automated tests, but require interaction. Automated tests are written using Evidence.js.

Detailed test information such as specific failures is logged to the JavaScript console of your browser.

It's possible to run automated tests from the command-line in headless Webkit with PhantomJS:

# install on Mac OS
$ brew install phantomjs

# run all tests
$ rake test

# run individual files
$ script/test test/selector.html

Code style guidelines

• function name() { } for named functions
• function(){ } for anonymous functions
• No curly braces for single-line control flow statements such as if & friends
• Don't write semicolons that are optional
• Put a single semicolon before statements that start with ( or [ (see above article as for why it's needed)
• Use long, descriptive variable and method names
• Use blank lines to separate "paragraphs" of code for readability
• Use comments to describe non-obvious code behavior
