Quick Start

Simple, Intuitive API

Get connected in minutes with a clean, event-driven API that feels natural in both Delphi and .NET.

Delphi 
procedure TForm1.FormCreate(Sender: TObject);
begin
  sgcWebSocketClient1.Host := 'www.esegece.com';
  sgcWebSocketClient1.Port := 2053;
  sgcWebSocketClient1.TLS := True;
  sgcWebSocketClient1.Active := True;
end;

procedure TForm1.sgcWebSocketClient1Connect(Connection: TsgcWSConnection);
begin
  Connection.WriteData('Hello sgcWebSockets!');
end;

procedure TForm1.sgcWebSocketClient1Message(Connection: TsgcWSConnection;
  const Text: string);
begin
  Memo1.Lines.Add('Received: ' + Text);
end;
Delphi 
procedure TForm1.FormCreate(Sender: TObject);
begin
  sgcWebSocketHTTPServer1.Port := 8080;
  sgcWebSocketHTTPServer1.SSL := True;
  sgcWebSocketHTTPServer1.SSLOptions.CertFile := 'server.pem';
  sgcWebSocketHTTPServer1.SSLOptions.KeyFile := 'server.key';
  sgcWebSocketHTTPServer1.Active := True;
end;

procedure TForm1.sgcWebSocketHTTPServer1Message(Connection: TsgcWSConnection;
  const Text: string);
begin
  // Echo message back to client
  Connection.WriteData(Text);
end;

procedure TForm1.sgcWebSocketHTTPServer1Connect(Connection: TsgcWSConnection);
begin
  Log('Client connected: ' + Connection.Guid);
end;
C# 
using esegece.sgcWebSockets;

var client = new TsgcWebSocketClient();
client.Host = "www.esegece.com";
client.Port = 2053;
client.TLS = true;

client.OnConnect += (sender, connection) =>
{
    connection.WriteData("Hello from .NET!");
};

client.OnMessage += (sender, connection, text) =>
{
    Console.WriteLine($"Received: {text}");
};

client.Active = true;
