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, FreeBSD and Windows.

Its main features are as follows:

  • Use a non-blocking I/O network lib based on epoll (kqueue under macOS/FreeBSD) to provide high-concurrency, high-performance network IO, please visit the TFB Tests Results 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. Views are described by CSP template files, C++ codes are embedded into Html pages through CSP tags. And the drogon command-line tool automatically generates the C++ code files 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 handling HTTP requests;
  • Support https (based on OpenSSL);
  • Support WebSocket (server side and client side);
  • Support JSON format request and response, very friendly to the Restful API application development;
  • Support file download and upload;
  • Support gzip, brotli 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 non-blocking I/O based asynchronously reading and writing database (PostgreSQL and MySQL(MariaDB) database);
  • Support asynchronously reading and writing sqlite3 database based on thread pool;
  • Support ARM Architecture;
  • Provide a convenient lightweight ORM implementation that supports for regular object-to-database bidirectional mapping;
  • Support plugins which can be installed by the configuration file at load time;
  • Support AOP with build-in joinpoints.
