It does not make sense to catch the errors thrown by JSON.stringify()
and convert them to an ERROR packet (which are meant for namespace
authentication errors), it should be caught higher in the stack.

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]);
}
});
See the test suite for more examples of how socket.io-parser is used.
