**Drogon** is a C++14/17-based HTTP application framework. Drogon can be used to easily build various types of web application server programs using C++. **Drogon** is the name of a dragon in the American TV series "Game of Thrones" that I really like.
Drogon's main application platform is Linux. It also supports Mac OS and FreeBSD. Currently, it does not support windows. Its main features are as follows:
* Use a NIO network lib based on epoll (kqueue under MacOS/FreeBSD) to provide high-concurrency, high-performance network IO, please visit the [benchmarks](https://github.com/an-tao/drogon/wiki/benchmarks) page for more details;
* Support back-end rendering, the controller generates the data to the view to generate the Html page, the view is described by a "JSP-like" CSP file, the C++ code is embedded into the Html page by the CSP tag, and the drogon command-line tool automatically generates the C++ code file for compilation;
* Support view page dynamic loading (dynamic compilation and loading at runtime);
* Provide a convenient and flexible routing solution from the path to the controller handler;
* Support filter chains to facilitate the execution of unified logic (such as login verification, Http Method constraint verification, etc.) before controllers;
