Examples

Connecting to a TCP Server

var sock = net.connect("echo.websocket.events", 80);

sock.send("GET / HTTP/1.1\r\nHost: echo.websocket.events\r\n\r\n");
var response = sock.recv(1024);

print("Received:\n" + response);
sock.close();

Simple TCP Echo Server

var server = net.listen(9000, fn(client) {
    print("New connection established!");

    var data = client.recv(1024);
    while (len(data) > 0) {
        client.send("ECHO: " + data);
        data = client.recv(1024);
    }

    client.close();
});
