What is socket.io-parser?

The socket.io-parser npm package is a component of the Socket.IO ecosystem, which is used for encoding and decoding messages that are sent over the Socket.IO protocol. It handles the serialization and deserialization of the various types of messages that can be transmitted, such as events, binary data, and control packets.

What are socket.io-parser's main functionalities?

Encoding messages

This feature allows you to encode messages into a format that can be transmitted over the Socket.IO protocol. The code sample represents a JSON string that has been encoded by the socket.io-parser for an event with some data.

{"type":2,"nsp":"/","data":["event",{"some":"data"}]}

Decoding messages

This feature is used to decode messages received over the Socket.IO protocol. The code sample shows how an encoded message (a string) is decoded back into its original form using the socket.io-parser.

const encodedMessage = '4hello world';
const decodedMessage = parser.decode(encodedMessage);
console.log(decodedMessage);

Binary support

The socket.io-parser can handle binary data by encoding and decoding it as part of the message. The code sample demonstrates how to encode an ArrayBuffer as binary data within a message.

const binaryData = new ArrayBuffer(100);
const message = parser.encodeAsBinary({ type: 5, data: binaryData });
console.log(message);
