Simple, multithread-based(not thread safe), non-blocking asynchronous Client-Server classes in C++ for TCP & UDP. Creates a thread for every connection. Use mutexes or atomic variables to provide thread-safe functions.

// Initialize a tcp socket.
TCPSocket tcpSocket;
// Connect to the host.
tcpSocket.Connect("127.0.0.1", 8888, [&] {
 cout << "Connected to the server successfully." << endl;
 // Send String:
 tcpSocket.Send("Hello Server!");
});

Super Easy!

CPU & RAM Usages (with single tcp connection & with single udp server + client): Lightweight

Lightweight!

Examples You can compile all the examples by just going in the examples/ directory and run make in terminal:

• examples/tcp-client.cpp
• examples/tcp-server.cpp
• examples/udp-client.cpp
• examples/udp-server.cpp

• Linux
• MacOS (not tested)
