I wonder how this user was able to make it possible.

> Yeah, the whole backend is powered by message\_bus. The android/ios client long-polls. Not sure if this is the best use of message\_bus, but It works w/o the added complexity of web sockets. The major win is that it fits in our existing rails stack. The only disadvantage i’ve come across so far is that I can’t find an elegant way to support the typing indicator.

He publish a youtube video [here](https://youtu.be/5uNg9HopoGs?si=AebJZGi01dyRHhwq) showing his progress in multiple devices.

There should be a way to user the message\_bus gem from outside the discourse site.

Thanks a lot if you can juste guide me a little bit more, or give some idea
