Submitting Resources to Cocos Store

Cocos Creator has a built-in Extension Store for users to browse, download and automatically install official or third-party extensions and resources. Users can also submit their own extensions, art materials, music and sound effects to the extension store for sharing or selling. Here is an example of submitting an extension.


Packaging the Extension

Suppose the developer completes a extension package with the following directory structure:


Developers need to package the foobar folder into a file and submit it to the Cocos Developer Center.

For additional information on extension packages, please review the Creating Extension Packages documentation.

Third-party Libraries

There is currently no workflow for installing an included management system such as NPM in the extension package installation system, extension packages that use third-party libraries should be packaged in a zip package with folders such as node_modules.
