socket.io-cbor-x-parser

An alternative to the default socket.io-parser, encoding and decoding packets with cbor-x.

Please note that you MUST use the parser on both sides (server & client).

See also:

• the default parser: https://github.com/socketio/socket.io-parser
• a parser based on JSON.stringify/parse: https://github.com/darrachequesne/socket.io-json-parser
• a parser based on Notepack (msgpack): https://github.com/socketio/socket.io-msgpack-parser

Usage

const io = require('socket.io');
const ioc = require('socket.io-client');
const customParser = require('socket.io-cbor-x-parser');

const server = io(PORT, {
  parser: customParser
});

const socket = ioc('ws://localhost:' + PORT, {
  parser: customParser
});

socket.on('connect', () => {
  socket.emit('hello');
});
