How can I handle WebSocket errors in Angular using RxJS?

You can handle WebSocket errors in Angular by using RxJS operators like catchError and retry. Would you like a code example?

Yes, please provide a code example.

Here's a simple example:

import { WebSocketSubject } from 'rxjs/webSocket';
import { catchError, retry } from 'rxjs/operators';

const socket$ = new WebSocketSubject('ws://your-websocket-url');

socket$.pipe(
  retry(3), // Retry connection 3 times
  catchError(err => {
    console.error('WebSocket error:', err);
    return []; // Handle error
  })
).subscribe(
  msg => console.log('Message received:', msg),
  err => console.error('Error:', err)
);

This code will attempt to reconnect up to 3 times on error.

What should I do if the WebSocket connection fails after retries?

If the connection fails after retries, you can implement a backoff strategy or notify the user about the connection issue. You might also consider providing a button to retry the connection manually.
