Web Development with Twisted
Twisted has a long and checkered past in web development. This page is a roadmap to the wilderness that the landscape of web development with Twisted has become.
What's Going On Around Here
There are a number of packages in and around Twisted that do things with the web:
- Twisted Web provides a simple, stable resource publishing API, on top of an HTTP/1.0 server implementation with some HTTP/1.1 features. Twisted Web is widely regarded as clunky and old, but extremely stable.
- Several deprecated templating toolkits included with twisted.web, such as "woven" and "twisted web widgets". Don't use these! They're only there for compatibility.
- Twisted Web 2? is a complete re-write of Twisted Web, with a new HTTP/1.1 implementation and a new, more powerful and efficient resource publishing model. Unfortunately, it is currently still a work in progress. Some aspects of its design are not finalized, but it is ready for interested early-adopting developers. If you are going to use Web 2, you really need to stay current with recent developments in Twisted; subscribe to RSS feeds of changes to trunk, etc.
- Divmod Nevow is a templating toolkit that provides its own resource model and simple application server API. It requires Twisted, is fully integrated with the Twisted reactor, provides mechanisms for asynchronous page rendering, and an event-driven COMET/AJAX implementation called Nevow Athena. Currently Nevow uses Twisted Web but it will be ported to Twisted Web 2 once that stabilizes.
- Divmod Mantissa is a full-featured multi-protocol application server, with a built-in object database, authentication model based on Twisted Cred, a capability-based security model, and many more features. It integrates Nevow, twisted.web, and a number of other Twisted-related technologies to provide a full-featured system.
So You Want To Be A Web Developer
Having reviewed this list, the obvious question is, which of these tools should I use for my application??? The short answer is: "It depends."
