How difficult is it to implement your mini messenger in React/ReactNative?

Question

Node.js

For practice, I want to write my own mini Messenger, with the possibility of Registration, Messages, as in TG and some other basic functions on React / ReactNative.
Due to the lack of experience, I’m wondering if it’s worth trying, because I don’t know how difficult it is, and I haven’t found any guides, articles on writing Messenger on the Internet, it would be nice if someone could throw some information and an approximate stack technology required for this. I write on NodeJS server

Answer 1

The devil is in the details. I added the functionality of the messenger in a week. This is front and back and deployment. And then the customer began to be weird, we need smooth animation and floating from the bottom. In general, none of me is a front-ender.

Answer 2

The main difficulty is to implement online message updates. To do this, you must use the Web Socket technology.
Building a Web Socket capable backend is very easy these days with serveless technology .
But before that, you need to create a user pool with authentication. You can understand how to do this from this tutorial .
After you create a database and deploy the back like here .
And connect for example this lib for chat.
