Chat feature in mobile app - angularjs

I am creating a ionic mobile app for android and ios. There is this requirement to have a feature where two people can chat in this app.
Are there any existing free/paid API's that can be easily integrated with my application to achieve this task?

Firebase has a demo app that does exactly that:

Can be used pwa as a desktop rwd website simultaneously?

I want to create a web application. Before knowing about pwa, i wanna to create my wep app with rwd(responsive web design) that implements by react.
I don't want to have two seperated url and site for pwa and desktop. What could i do? Can i use serviceworker and manifest in root of my rwd design ? When users go to url in mobile, they see pwa and in desktop they see rwd. Just with one url. Thanks.
Yes service workers and manifest will help you accomplish this. The pwa will be from the Responsive Web Design, meaning you Progressive Web App is linked to the rwd.

How to convert Ionic mobile to web app

Say I have an existing mobile app built on Ionic. Now I need to have a website version of the app so users can access it via desktop too.
Is there any documentation that suggest this is possible?
I think you're looking for Progressive Web Apps. Ionic does cater for such, just google for the term "Ionic PWA" example below.

Using trigger.io with GAE

I want to try using trigger.io.
We have a Web App and using GAE.
How can we test our Web App with trigger.io?
I see that on the "WEB" section of the toolkit there's only a spot for "Heroku".
Is it possible?
Do we need to migrate?
How can i test our web app with android? I couldn't find a place to direct it to our index.html.
Thanks a lot.
The web section in the Toolkit basically lets you deploy your mobile app as a mobile website, based on Node.js.
If you have an existing web app that you'd like to use as the backend for a mobile app, then it's a case of exposing some sort of HTTP API which your mobile app then interacts with.
Having the mobile app just receive JSON from GAE, build its HTML views and present them to the user works really well.

Is AWS(S3, EC2) a good backend fit for an appcelerator mobile app?

I am looking to supplement a website i am building using web2py with a mobile app. Titanium seems good to work with and was wondering if i should just use AWS for my backend on both my website and mobile app. I am also interested in an answer if i was just developing the mobile app only not a website as well.
Kind Regards
I created a simple API to access data from an app I developed with Titanium. It is hosted on EC2 and I have been very happy with the performance so far.
