What are the steps to configure a WebSocket server in SvelteKit using the ws library?

edit

Import the ws library and define a new WebSocketServer instance. Here's an example of how to do this:

import WebSocketServer from 'ws';

const wss = new WebSocketServer.Server({ port: 8080 });

This creates a new WebSocket server on port 8080.

Next, add some event listeners to handle various WebSocket events. For example, to handle connections and disconnections, you could add the following code:

wss.on('connection', (ws) => {
 console.log('Client connected');

 ws.on('close', () => {
   console.log('Client disconnected');
 });
});

This will log a message to the console whenever a client connects or disconnects.

In your SvelteKit project, import the wss object and use it to broadcast data to all connected clients. For example, you could call wss.clients.forEach() to send data to all clients:

import wss from '$lib/websocket';

// send a message to all connected clients
wss.clients.forEach((client) => {
 client.send('Hello from the server');
});

Note that in order for this to work, you'll need to have a WebSocket connection open in your client-side JavaScript code.
