    xk6-tcp

    TCP Protocol Extension for k6

    This extension provides TCP socket functionality for k6 performance testing scripts, offering both synchronous and asynchronous APIs for network communication.

    Supports event-driven programming with lifecycle events (connect, data, close, error, timeout), TLS/SSL encryption, binary data handling, and comprehensive metrics collection.

    import { Socket } from 'k6/x/tcp';

    export default function () {
      const socket = new Socket();

      socket.on('connect', () => {
        console.log('Connected!');
        socket.write('GET / HTTP/1.1\r\nHost: example.com\r\n\r\n');
      });

      socket.on('data', (data) => {
        const response = String.fromCharCode.apply(null, new Uint8Array(data));
        console.log('Received:', response.substring(0, 100));
        socket.destroy();
      });

      socket.on('close', () => {
        console.log('Connection closed');
      });

      socket.connect(80, 'example.com');
    }
