socket.io-json-parser

An alternative to the default socket.io-parser, encoding and decoding packets with JSON.parse / stringify.

With that parser, binary data (ArrayBuffer / Buffer / Blob / File) is not supported.

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

- the default parser: https://github.com/socketio/socket.io-parser
- a parser based on msgpack: https://github.com/darrachequesne/socket.io-msgpack-parser

Usage

``js
const io = require('socket.io');
const ioc = require('socket.io-client');
const customParser = require('socket.io-json-parser');

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

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

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

Format

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

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

which will be encoded by the parser as:

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