• 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 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;
    • 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 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 AOP with build-in joinpoints.
