WebSocket Data Framing and Messages

When you send data over a network, it's not just a raw stream of bits. It needs structure! Think of it like sending a letter:

• You need an envelope (the frame).
• You need a stamp (protocol headers).
• You need the actual message inside.

WebSockets use a similar concept called data framing.

A WebSocket frame is the basic unit of data transfer over a WebSocket connection. Instead of sending one big message, WebSockets break data into smaller, manageable frames.

This allows for:

• Sending parts of a message over time.
• Mixing different types of data.
• Controlling the connection itself.
