Sending and Receiving Data
Implement methods for sending messages to the server and handling incoming data from the server.
Client Data Exchange Intro
Welcome back! In the previous lessons, we learned about establishing WebSocket connections. Now, let's dive into the core of realtime communication: sending and receiving data.
This lesson will show you how to implement methods for clients to send messages to a WebSocket server and how to handle incoming data from that server.
Sending Data with `send()`
To send data from your client to the WebSocket server, you'll use the WebSocket.send() method. It's quite straightforward!
- You can send various data types: plain text (strings), binary data (like
BloborArrayBuffer). - The server will receive this data and can then process it or even broadcast it to other connected clients.
