Usage

Example

const io = require('socket.io');
const ioc = require('socket.io-client');
const customParser = require('@skgdev/socket.io-msgpack-javascript');
const server = io(PORT, {
  parser: customParser.build({
      encoder: ?EncodeOptions,
      decoder: ?DecodeOptions
  })
});

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

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

Format

socket.emit('hello', 'you') will create the following packet:

{
  "type": 2,
  "nsp": "/",
  "data": ["hello", "you"]
}

which will be encoded by the parser as:

<Buffer 83 a4 74 79 70 65 02 a3 6e 73 70 a1 2f a4 64 61 74 61 92 a5 68 65 6c 6c 6f a3 79 6f 75>
