Pyramid is a web application framework designed to accommodate projects ranging from small services to larger applications with complex requirements. It provides a flexible core without requiring developers to adopt a particular database, template engine or application layout.
The framework supports different approaches to mapping incoming requests onto application code. URL dispatch associates request paths with routes, while traversal resolves resources through an application-defined hierarchy.
Pyramid’s configuration system allows components and policies to be assembled according to the needs of a particular project. Applications can begin with a small set of views and introduce authentication, rendering, internationalisation and other services as required.
This is free and open source software.
Key Features
- URL dispatch and resource traversal for resolving incoming requests.
- View configuration using decorators or imperative registration.
- Route and view predicates for selecting handlers based on request characteristics.
- Renderer system for converting application data into HTTP responses.
- Support for multiple template engines within a single application.
- Authentication and authorisation through configurable security policies.
- Cross-Site Request Forgery protection using session-based or cookie-based tokens.
- Session management with configurable storage and session factories.
- Event subscribers for reacting to application and request lifecycle events.
- Tweens for inserting middleware-like processing around view execution.
- Static asset handling and package-based resource specifications.
- Internationalisation and localisation utilities.
- URL generation and customisable request methods.
- Exception views and configurable HTTP error handling.
- Extensible configuration system supporting reusable add-ons.
