Revel is a full-stack web framework and toolkit for building applications with the Go language. It implements a model-view-controller architecture to separate business logic from user interface rendering, providing a comprehensive system for routing, parameter binding, and session management.
The project distinguishes itself with a high-productivity development environment featuring automatic code compilation and hot-reloading, which refreshes the application state and templates upon file changes without requiring manual restarts. It also employs reflection-based parameter binding to automatically convert raw request data into typed variables.
The framework covers a broad range of capabilities, including server-side HTML rendering with pluggable template engines, bidirectional WebSocket communication, and a composable middleware filter chain. Additional support is provided for signed cookie session management, content internationalization, asynchronous background job execution, and hierarchical application logging.
The system includes utilities for managing the application lifecycle, from ordered startup initialization to shutdown hooks.
