Implement instant messaging app

[ccnamtan]

I would like to implement instant messaging app like messenger or whatsapp or line.

Have they implemented by opening socket?

What are pros/cons for opening socket and polling?

Do you have the example or tutorial for implementing this?

Hi @ccnamtan, here is a tutorial for creating a real time chat app using Firebase: https://www.raywenderlich.com/5359-firebase-tutorial-real-time-chat .

Here are two more tutorials that focus on sockets:
