Encoding messages

This feature allows you to encode a message packet into a format suitable for transport over the network. The `encodePacket` function takes a packet object and a callback function that receives the encoded packet.

const { encodePacket } = require('engine.io-parser');
const packet = { type: 'message', data: 'hello' };
encodePacket(packet, false, (encodedPacket) => {
  // handle the encoded packet
});

Decoding messages

This feature allows you to decode a message packet that was received from the network. The `decodePacket` function takes an encoded packet and the type of data ('string' or 'binary') and returns the decoded packet object.

const { decodePacket } = require('engine.io-parser');
const encodedPacket = '2hello'; // example of an encoded message packet
const packet = decodePacket(encodedPacket, 'string');
// handle the decoded packet

Support for binary data

This feature provides support for encoding and decoding binary data. The `encodePacket` and `decodePacket` functions can handle binary data when the second argument is set to `true` for binary.

const { encodePacket, decodePacket } = require('engine.io-parser');
const binaryData = new ArrayBuffer(100);
const packet = { type: 'message', data: binaryData };
encodePacket(packet, true, (encodedPacket) => {
  // handle the encoded packet with binary data
});
const decodedPacket = decodePacket(encodedPacket, 'binary');
// handle the decoded packet with binary data
