    Cocos2D JavaScript is an HTML5 port of the popular iPhone 2D graphics engine Cocos2D. It allows rapid development of 2D games and graphical applications which can run in any modern Web browser.


    Follow the instructions for your given platform or skip ahead to 'manual installation' if you want to install from git.


    Download and launch the installer.

    Linux or Mac OS X using npm

    If you have Node.js and npm installed you can install Cocos2D JavaScript as a package.

    npm install cocos2d

    Linux or Mac OS X using ZIP archive

    If you don't have, or don't want to use npm, you can install by downloading the latest ZIP.

    Then from your terminal run sudo ./ The script will copy Cocos2D JavaScript to a global location of your choice and symlink the executable to /usr/local/bin/cocos

    Manual Installation (all platforms)

    You don't need to use the installer if you don't want to. You can download the latest ZIP or checkout the latest version from github.

    If you checkout from github and don't have Node.js installed, be sure to also get the submodules as they include precompiled Node.js binaries.

    git submodule update --init

    With all the code read you can copy it to any place you want and from there use the '', 'cocos.bat' or .EXEs in bin/ as you would normally.

    Creating your first project

    On Windows use the 'Create project' shortcut from your start menu to create and select a location for your new project.

    On Linux and Mac OS X open your terminal and run:

    cocos new ~/my_first_project

    This will create a barebones project which simply draws the project name in the centre of the screen.

    To test that it's working, on Windows double click the 'Serve project' shortcut in your project's folder.

    On Linux and Mac OS X from your terminal run:

    cd ~/my_first_project
    cocos server

    Now visit http://localhost:4000 and with a bit of luck you'll have something showing.


    Everything you write will be in separate JavaScript files. These will be compiled into a single file which also includes all your other resources including images, sound files, map files, etc.

    The entry point for the code is the file src/main.js which has an exports.main function that is called on startup.

    The HTML for your page is in public/index.html.

    Compiling your application

    You should never use the development server in production. It's very slow and insecure. Instead you will compile your application into a single JavaScript file. This file includes everything, you don't need to worry about hosting any external resources such as images and tilemaps.

    To do this, on Windows double click the 'Compile project' shortcut in your project's folder.

    On Linux and Mac OS X in your terminal run:

    cd ~/my_first_project
    cocos make

    The file will be written to build/. You can run this through a JavaScript minifier if you so choose. You will get a very good reduction in size if your Web server is configured to gzip JavaScript files.

    Browser Support

    Everything should work in Firefox 3, Chrome, Safari, Opera and IE9. If that is not the case then please file a bug report.


    Documentation can be viewed online at

    If you wish to generate the documentation yourself you need to follow these steps.

    Download JsDoc 2.3 (or 2.4) from

    Copy that to /usr/local/jsdoc-toolkit or wherever you like and then run:

    JSDOC_HOME=/usr/local/jsdoc-toolkit ./bin/jsdoc

    The documentation will appear in the 'docs' directory.
