What you need to build your own jQuery

In order to build jQuery, you need to have Node.js/npm latest and git 1.7 or later. (Earlier versions might work OK, but are not tested.)

For Windows you have to download and install git and Node.js.

Mac OS users should install Homebrew. Once Homebrew is installed, run brew install git to install git, and brew install node to install Node.js.

Linux/BSD users should use their appropriate package managers to install git and Node.js, or build from source if you swing that way. Easy-peasy.

How to build your own jQuery

Clone a copy of the main jQuery git repo by running:

git clone git://github.com/jquery/jquery.git

Enter the jquery directory and run the build script:

cd jquery && npm run-script build

The built version of jQuery will be put in the dist/ subdirectory, along with the minified copy and associated map file.

If you want create custom build or help with jQuery development, it would be better to install grunt command line interface as a global package:

npm install -g grunt-cli

Make sure you have grunt installed by testing:

grunt -v

Now by running grunt command, in the jquery directory, you could build full version of jQuery, just like with npm run-script build command:

grunt

There are many other tasks avaliable for jQuery Core:

grunt -help

Modules

Special builds can be created that exclude subsets of jQuery functionality. This allows for smaller custom builds when the builder is certain that those parts of jQuery are not being used. For example, an app that only used JSONP for $.ajax() and did not need to calculate offsets or positions of elements could exclude the offset and ajax/xhr modules.

Any module may be excluded except for core, and selector. To exclude a module, pass its path relative to the src folder (without the .js extension).

Some example modules that can be excluded are:

• ajax: All AJAX functionality: $.ajax(), $.get(), $.post(), $.ajaxSetup(), .load(), transports, and ajax event shorthands such as .ajaxStart().
• ajax/xhr: The XMLHTTPRequest AJAX transport only.
• ajax/script: The `
