Uvicorn
Uvicorn is an ASGI web application host designed for asynchronous Python web development. It serves applications through a standardized asynchronous server gateway interface to handle non-blocking network traffic and high-concurrency requests.
The server manages both HTTP and WebSocket traffic, including the handshaking process required to establish persistent, full-duplex communication channels for real-time data exchange.
For development workflows, the project includes a hot-reload mechanism that monitors the filesystem for source code changes and automatically restarts the server process.
Features
- ASGI-Based - Implements the ASGI specification to serve as a high-performance asynchronous server gateway interface.
- Event Loop Replacements - Provides a high-performance event loop replacement based on libuv to handle massive concurrency.
- WebSocket Servers - Acts as a server-side implementation that maintains persistent, bidirectional WebSocket communication channels.
- HTTP Traffic Handling - Processes incoming HTTP and WebSocket traffic to facilitate real-time communication between clients and servers.
- Non-Blocking Socket I/O - Employs non-blocking socket I/O to handle multiple concurrent network connections without stalling.
- Web Development - Enables the building and hosting of asynchronous web services using Python's async features.
- Real-Time Communication - Supports persistent, bidirectional data streaming through full-duplex WebSocket communication.
- Hot-Reloading Servers - Provides a development server that automatically refreshes when source code changes are detected.
- Process Watchers - Includes a process watcher that monitors for filesystem changes to automatically restart the server during development.
- Connection Handshake Protocols - Handles the initial HTTP upgrade handshake required to establish a bidirectional WebSocket channel.
- Protocol Upgrades - Manages the protocol upgrade process to transition HTTP requests into persistent WebSocket connections.
- Automatic Process Restarters - Automatically restarts the server process when source code modifications are detected on the filesystem.
- ASGI Servers - High-performance ASGI server using modern event loops.
- Web Frameworks - Lightning-fast ASGI server implementation.
