Hey guys, I made an open-source Express like non blocking HTTP Server library in C++. Starting a new web server is as simple as initiating the app with the desired port (8080 default) and start registering routes.

#include <PlusWeb/HttpServer.h>

int main() { HttpServer app(3000);

    app.GET("/users/:id", [](HttpRequest& req, HttpResponse& res) {
        res.status(200).send(nlohmann::json{
            {"id", req.params["id"]},
            {"name", "ada"},
        });
    });

    app.serve([] { std::cout << "listening on :3000\n"; });

}

It supports middleware chaining and since it uses tries for storing routes instead of a flat array like Express, the performance gets better as the application scales up

For example: At 5 Routes PlusWeb is 4.8x faster than express whereas at 10,000 routes it is 253x faster than express
