socket.io-parser

A socket.io encoder and decoder written in JavaScript complying with version `4` of socket.io-protocol. Used by socket.io and socket.io-client.

# Parser API

socket.io-parser is the reference implementation of socket.io-protocol. Read the full API here: socket.io-protocol.

# Example Usage

## Encoding and decoding a packet

var parser = require('socket.io-parser');
var encoder = new parser.Encoder();
var packet = {
type: parser.EVENT,
data: 'test-packet',
id: 13
};
encoder.encode(packet, function(encodedPackets) {
var decoder = new parser.Decoder();
decoder.on('decoded', function(decodedPacket) {
// decodedPacket.type == parser.EVENT
// decodedPacket.data == 'test-packet'
// decodedPacket.id == 13
});
for (var i = 0; i < encodedPackets.length; i++) {
decoder.add(encodedPackets[i]);
}
});

## Encoding and decoding a packet with binary data

var parser = require('socket.io-parser');
var encoder = new parser.Encoder();
var packet = {
type: parser.BINARY_EVENT,
data: {i: new Buffer(1234), j: new Blob([new ArrayBuffer(2)])}
id: 15
};
encoder.encode(packet, function(encodedPackets) {
var decoder = new parser.Decoder();
decoder.on('decoded', function(decodedPacket) {
// decodedPacket.type == parser.BINARY_EVENT
// Buffer.isBuffer(decodedPacket.data.i) == true
// Buffer.isBuffer(decodedPacket.data.j) == true
// decodedPacket.id == 15
});
for (var i = 0; i < encodedPackets.length; i++) {
decoder.add(encodedPackets[i]);
}
});
