Documentation for Roda (v3.2.0)
README (Introduction to Roda, start here if new)
Here are direct links to the most important pages:
- Roda ClassMethods (used for configuring Roda)
- Roda InstanceMethods (minimal so as not to pollute the scope)
- Roda RequestMethods (all the methods for routing requests, such as r.on)
- Roda ResponseMethods (methods for manipulating the response directly)
Plugins are a very important part of Roda, since by design Roda has a very small core.
