Drogon: A C++14/17 based HTTP web application framework running on Linux/macOS/Unix

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 page for more details;
• Provide a completely 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, controllers and views.
• Support 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);
• 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;
• Support https (based on OpenSSL);
• Support WebSocket (server side);
• Support JSON format request and response, very friendly to the Restful API application development;
• Support file download and upload;
• Support gzip compression transmission;
• Support pipelining;
• Provide a lightweight command line tool, drogon_ctl, to simplify the creation of various classes in Drogon and the generation of view code;
• Support NIO-based asynchronously reading and writing database (PostgreSQL and MySQL(MariaDB) database);
• Support asynchronously reading and writing sqlite3 database based on thread pool;
• Provide a convenient lightweight ORM implementation that supports for regular object-to-database bidirectional mapping;
