send data from a ionic based hybrid app to a web app?

I have created a Hybrid app using Ionic 1 and Node.js. They communicate via REST API's and Socket.io. I have another app built with AngularJS and NodeJS, They communicate similarly too. Now I want both the frontends to exchange data. According to what I have gathered after a lot of reading is this.

NodeJS(App 1) ---> Node JS(App 2) via RabbitMQ[].(This is the part I am unsure about.) 
    | (socket)         |(socket)
Frontend 1            Frontend 2

and that's how data from 1 frontend will transfer to another. Is there a better way to do this. Just to put some context. I am trying to show some location data collected from mobile app, into a web based frontend.
