Fast and versatile web framework in modern C++
Webserver is a lightweight, high-performance framework built on top of Uvent.
It provides everything you need to handle HTTP/1.0 and HTTP/1.1 efficiently, with planned support for HTTP/2 and HTTP/3.
- 🚀 High-performance async event loop (via Uvent)
- 📦 RFC-compliant HTTP parser
- 🔌 Middleware and routing system (regex & radix)
- 🧩 Modular and extensible design
- 🔒 TLS/SSL support (optional, OpenSSL)
Minimal server:
#include <cstdint>
#include <iostream>
#include <uvent/Uvent.h>
#include <unet/core/config.hpp>
#include <unet/http.hpp>
#include <unet/http/router/radix.hpp>
using Request = usub::unet::http::Request;
using Response = usub::unet::http::Response;
usub::uvent::task::Awaitable<void> handle_any(Request &, Response &response) {
response.setStatus(200)
.addHeader("content-type", "application/json")
.setBody(R"({"status":"success"})");
co_return;
}
usub::unet::core::Config make_server_config() {
usub::unet::core::Config config{};
usub::unet::core::Config::Object stream_cfg{};
stream_cfg["host"] = usub::unet::core::Config::Value{std::string{"0.0.0.0"}};
stream_cfg["port"] = usub::unet::core::Config::Value{static_cast<std::uint64_t>(45901)};
stream_cfg["backlog"] = usub::unet::core::Config::Value{static_cast<std::uint64_t>(128)};
stream_cfg["version"] = usub::unet::core::Config::Value{static_cast<std::uint64_t>(4)};
stream_cfg["tcp"] = usub::unet::core::Config::Value{std::string{"tcp"}};
usub::unet::core::Config::Object http_cfg{};
http_cfg["PlainTextStream"] = usub::unet::core::Config::Value{std::move(stream_cfg)};
config.root["HTTP"] = usub::unet::core::Config::Value{std::move(http_cfg)};
return config;
}
int main() {
usub::Uvent runtime{8};
auto config = make_server_config();
usub::unet::http::ServerRadix server{runtime, config};
server.handle("*", "/", handle_any);
std::cout << "minimal http server listening on http://127.0.0.1:45901\n";
