** **
uv-cpp is a simple interface, high-performance network library based on C++11.
## Dependencies
* [libuv][1]
## Features
* C++11 functional/bind style callback instead of C-style function pointer.
* `TCP` and `UDP` wrapper.
* `DNS`and`Http`：DNS query and http support，Http routing based on radix tree.
* `Timer`and`TimerWheel`：Heartbeat timeout judgment with time complexity of O(1).
* `Async`：libuv async wrapper，but optimized the [problem][2] of calling multiple times but callback will only be called once.
* `Packet`and`PacketBuffer`：Send and receive packet of Tcp data stream. Support custom data packet structure (such as [uvnsq][3])
* Log interface.
** **
## Build Instructions
* VS2017 (windows)
* Codeblocks (linux)
* CMake (linux)
** **

## Quick start
A simple echo server
```C++
#include
#include
int main(int argc, char** args)
{
uv::EventLoop* loop = uv::EventLoop::DefaultLoop();
uv::TcpServer server(loop);
server.setMessageCallback([](uv::TcpConnectionPtr ptr,const char* data, ssize_t size)
{
ptr->write(data, size, nullptr);
});
//server.setTimeout(60); //heartbeat timeout.
uv::SocketAddr addr("0.0.0.0", 10005, uv::SocketAddr::Ipv4);
server.bindAndListen(addr);
loop->run();
}
```
A simple http service router which based on radix tree.
```C++
int main(int argc, char** args)
{
uv::EventLoop loop;
uv::http::HttpServer::SetBufferMode(uv::GlobalConfig::BufferMode::CycleBuffer);
uv::http::HttpServer server(&loop);
//example: 127.0.0.1:10010/test
server.Get("/test",std::bind(&func1,std::placeholders::_1,std::placeholders::_2));
//example: 127.0.0.1:10010/some123abc
server.Get("/some*",std::bind(&func2, std::placeholders::_1, std::placeholders::_2));
//example: 127.0.0.1:10010/value:1234
server.Get("/value:",std::bind(&func3, std::placeholders::_1, std::placeholders::_2));
//example: 127.0.0.1:10010/sum?param1=100¶m2=23
server.Get("/sum",std::bind(&func4, std::placeholders::_1, std::placeholders::_2));
uv::SocketAddr addr("127.0.0.1", 10010);
server.bindAndListen(addr);
loop.run();
}
