(Node.js) Socket/SSL/TLS through SOCKS5 / SOCKS4 Proxy

Demonstrates how to use the Chilkat Socket/SSL/TLS component/library with a SOCKS5 or SOCKS4 proxy server.

Install Chilkat for Node.js and Electron using npm at Chilkat npm packages for Node.js Chilkat npm packages for Electron on Windows, Linux, MacOS

    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    var socket = new chilkat.Socket();

    // To use a SOCKS4 or SOCKS5 proxy, simply set the following
    // properties prior to calling Connect.  The connection may be SSL/TLS or 
    // non-secure - both will work with a SOCKS proxy.
    // The SOCKS hostname may be a domain name or 
    // IP address:
    socket.SocksHostname = "www.mysocksproxyserver.com";
    socket.SocksPort = 1080;
    socket.SocksUsername = "myProxyLogin";
    socket.SocksPassword = "myProxyPassword";
    // Set the SOCKS version to 4 or 5 based on the version
    // of the SOCKS proxy server:
    socket.SocksVersion = 5;
    // Note: SOCKS4 servers only support usernames without passwords.
    // SOCKS5 servers support full login/password authentication.

    // Connect to port 5555 of 192.168.1.108.
    // hostname may be a domain name or IP address.
    var hostname = "192.168.1.108";
    var ssl = false;
    var maxWaitMillisec = 20000;

    // Set maximum timeouts for reading an writing (in millisec)
    socket.MaxReadIdleMs = 10000;
    socket.MaxSendIdleMs = 10000;

    // The server (in this example) is going to send a "Hello World!" 
    // message.  Read it:

        console.log(socket.LastErrorText);

    // Wait a max of 20 seconds (20000 millsec)
