The InterApp API allows you to launch other apps, as well as respond to being launched via URI schemes.

This module is an EventEmitter, so the methods from EventEmitter can be used to listen to events.

You need to add a reference to "Fuse.Launcher" in your project file to use this feature.


var InterApp = require("FuseJS/InterApp");

InterApp.on("receivedUri", function(uri) {
    console.log("Launched with URI", uri);


In the above example we're using the EventEmitter on method to listen to the "receivedUri" event.

For the receivedUri event to be triggered, you need register a custom URI scheme for your app, as shown here.
