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. For debugging purposes, it also supports Mac OS. There is no plan to support Windows. Its main features are as follows: * The network layer uses a NIO framework based on epoll (poll under MacOS) to provide high-concurrency, high-performance network IO; * Full asynchronous programming mode; * Support Http1.0/1.1 (server side and client side); * Based on template, a simple reflection mechanism is implemented to completely decouple the main program framework, controller and view. * Support for cookies and built-in sessions; * 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); * Very convenient and flexible path to controller handler mapping scheme; * Support filter chain to facilitate the execution of unified logic (such as login verification, Http Method constraint verification, etc.) before the controller; * Support https (based on OpenSSL); * Support websocket (server side); * Support Json format request and response; * Support file download and upload; * Support gzip compression transmission; * Provides a lightweight command line tool, drogon_ctl, to simplify the creation of various classes in Drogon and the generation of view code; * Asynchronous database read and write based on NIO, currently supports PostgreSQL and MySQL (MariaDB) database; * Convenient lightweight ORM implementation that supports regular object-to-database bidirectional mapping; ### For more information, please visit the [wiki](https://github.com/an-tao/drogon/wiki)
