npm install ws
src
directory named websocket.js
. This file will contain the code for your WebSocket server.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.
wss
object so it can be accessed from other files in your SvelteKit project:
export default wss;
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.
