How can I implement WebSockets in an Angular application?

You can implement WebSockets in Angular using the WebSocket API. First, create a WebSocket connection in your service.

What are the steps to create a WebSocket service?

1. Create a new service using Angular CLI. 2. Use the WebSocket constructor to connect to your server. 3. Implement methods to send and receive messages.

Can you show me a code example?

Sure! Here's a simple example:

import { Injectable } from '@angular/core';

@Injectable({ providedIn: 'root' })
export class WebSocketService {
  private socket: WebSocket;

  constructor() {
    this.socket = new WebSocket('ws://yourserver.com');
  }

  sendMessage(message: string) {
    this.socket.send(message);
  }

  getMessages() {
    return new Observable(observer => {
      this.socket.onmessage = (event) => observer.next(event.data);
    });
  }
}

What should I consider for error handling?

You should handle connection errors, message errors, and implement reconnection logic to ensure reliability.
