encoded = encode(msg)
print(encoded)

Decode a message

msg = 'EWP 0.2 RPC 0 25\n{"id":1,"method_id":0x00}'
decoded = decode(msg)
print(JSON.stringify(decoded))

Here is a demo server

server.listen(PORT,HOST,function() {
	console.log("Server is listening on "+HOST+":"+PORT);
});

const client = new net.Socket();
const payload = "EWP 0.2 RPC 0 25\n{\"id\":1,\"method_id\":0x00}";

client.connect(PORT, HOST, function() {

	client.write(payload);
});

client.on("data", function(data) {

	const pongOutput = data.toString("utf-8")

	if(payload===pongOutput) {
		console.log("Test Passed: PONG OUTPUT === PING PAYLOAD");
	}

	client.destroy();
});
