A C++11 client library for the Socket.IO real-time event protocol, built on websocket++ with a JS-like API. It supports binary payloads, automatic JSON encoding, multiplexing, and works across desktop and mobile platforms.

Use cases

• connect a C++ app to a Socket.IO server
• build a real-time chat client in C++
• add websocket event messaging to a Qt application
• integrate Socket.IO into an iOS app
• emit and receive binary data over Socket.IO
• replace the JS Socket.IO client with a native C++ one

When to choose

• your backend uses Socket.IO 3.x/4.x and you need a native C++ client
• you need cross-platform real-time messaging in C++ including mobile
• you want a JS-like Socket.IO API with lambda event handlers

When to avoid

• you need HTTP long-polling fallback - only WebSocket transport is implemented
• you must connect to Socket.IO 1.x/2.x servers without allowEIO3
• you are not using C++11 or newer
