Here's how to connect and communicate with WebSocket servers from browser client applications using the WebSocket API and the WebSocket protocol.
// Create a WebSocket client in the browser.
const ws = new WebSocket("ws://localhost:1234");
// Log incoming messages to the console.
ws.onmessage = function (event) {
// This runs when receiving message.
console.log(event.data);
};
ws.onopen = () => {
// This runs when we connect.
// Submit a message to the server
ws.send(`Hello, WebSocket! Sent from a browser client.`);
};
