Muffin is a lightweight asynchronous web framework designed for building web applications and services around the ASGI standard. It combines a straightforward application structure with the ability to handle asynchronous requests and long-lived connections.
Applications are organised around routes that associate URL patterns with request handlers. Each handler receives a request object and returns content that Muffin converts into an appropriate HTTP response. This makes it possible to build small services without adopting an elaborate application architecture.
The framework supports several asynchronous execution libraries and can be extended through middleware and plugins. Developers can introduce additional functionality as their applications grow, including database integration, authentication, sessions and template rendering.
This is free and open source software.
Key Features
- ASGI-compatible framework supporting asynchronous HTTP applications and services.
- Supports Asyncio, Trio and Curio asynchronous execution libraries.
- Flexible URL routing with dynamic path parameters, type converters and regular expressions.
- Multiple response formats including HTML, JSON, text, file downloads, streaming responses and Server-Sent Events.
- WebSocket support for bidirectional communication between clients and servers.
- Middleware system for intercepting and processing requests and responses.
- Plugin ecosystem covering Jinja2 templates, databases, OAuth authentication, sessions, internationalisation and monitoring.
- Supports nested applications and host-based routing for organising larger projects.
- Background tasks can be scheduled to run after an HTTP response has been sent.
- Built-in facilities for serving static files, processing uploads and handling redirects and HTTP errors.
- Test client and pytest integration for testing application behaviour, including WebSocket connections.
- Configuration management with support for environment variables and plugin settings.
