## Description

Drogon is a high-performance, cross-platform C++ framework designed for building asynchronous web services and server-side applications. It functions as a multi-threaded, event-driven server engine that manages concurrent network traffic and WebSocket connections with minimal latency. By leveraging non-blocking input/output and native code compilation, the framework provides a foundation for scalable applications that operate efficiently across diverse hardware architectures.

The framework distinguishes itself through its compile-time template rendering, which transforms dynamic HTML views into native machine code to maximize execution speed. It also incorporates a sophisticated object-relational mapping layer that enables asynchronous database operations and persistent connection pooling, ensuring that data-heavy tasks do not stall the main execution thread. These capabilities are supported by a middleware-based filtering system that allows for the injection of custom logic and security policies throughout the request-response cycle.

Beyond its core engine, the framework provides a comprehensive suite of tools for modern web development, including RESTful service support, real-time bidirectional communication, and automated project scaffolding. It handles complex operational requirements such as request proxying, load balancing, and secure traffic management through integrated SSL/TLS configuration. The system also includes built-in support for monitoring, logging, and performance metrics export to maintain visibility into application health.

Developers can manage the entire application lifecycle through command-line tools that facilitate project generation, dependency management, and runtime configuration. The framework is designed to be portable, supporting cross-platform compilation to ensure consistent behavior across different operating systems.
