How to implement background cyclic requests to the server in Angular?

Question

Angular

This is necessary, for example, for a chat, to check whether a message has come from the interlocutor. Through the loop, the application will hang the browser heavily.

Answer 1

On idea to you it is necessary to do through setTimeout instead of through a cycle.
But in general, it is more correct to use web sockets for such purposes, since heaps of requests will load the server. And when the data itself comes through websockets, then everything works quickly and does not load the server.
