Getting Type of WebSocket Object (Best Practices)

[byzeagle]

I need to store websockets in an array for each connection made.

// Needed to go through the source files.
static std::vector<uWS::WebSocket<false, true, DataType> *> users; 

app.ws<DataType>("/ws", {
    
    .open = [](auto * ws){
        users.push_back(ws);
         // This is also possible, but not accessible inside .message
         static std::vector<decltype(ws)> users2;
        ws->subscribe("sensors/+/house");
    },

    .close = [](auto *ws, int code, std::string_view message){
        users.erase(std::remove(users.begin(), users.end(), ws), users.end());
        std::cout << "Client disconnected!" << std::endl;
    },

    .message = [](auto *ws, std::string_view message, uWS::OpCode opCode){
        try{
            std::string message2 = std::string(message) + std::string(" ACK");
            for(const auto & ws2 : users)
                if(ws != ws2)
                    ws2->send(message2, opCode);

        }catch(std::exception& e){
            std::cout << e.what() << std::endl;
        }
    },
});

My problem is I had to go through source files and find uWS::WebSocket<false, true, DataType> * declaration to declare my array for websocket connection while lambdas are declared with the auto keyword in the examples.

Is there a way to address type of websocket object without having to go through the source files?

Hi, I can totally relate to that. This is exactly what I did. I think this is more of a documentation thing.

Suggestion: maybe add an example for this use case?
