An approach is proposed to support cross-platform information exchange mechanism for integration of web-based components with a native application. First, mini apps are imported to a platform of a mobile device, wherein the mini apps are web-based features assembled and packaged together in JavaScript to be deployed to and integrated with the application native to the platform. A bridge enables bi-directional communication between the mini apps in JavaScript and the native to the platform by marshalling native code of the native application into a JavaScript project to be integrated with the imported mini apps and un-marshalling the mini apps in JavaScript to the native code of the native application. The mini apps are then integrated with the native application on the mobile device over the bridge to create a target mobile application, which is uploaded to an app store to make the target mobile application available to an end user.
