Answer 1

I think the front-end of multi-person editing is harder than the back-end. In fact, multi-person editing is essentially similar to a chat room. Synchronization between multiple people can be achieved using websocket, and the backend implements a service similar to echo server. The front-end editor feels like it requires a lot of code, and it depends on how rich text you want to achieve.

Answer 2

First you need an asynchronous framework, then you will use websocket, and the rest is to use the text editor. Finally, how often is the communication timed? Is it a process of waiting for the user to complete the input before sending or typing? It is sent once for each character input.
