Built on Clack
Stop reinventing the wheel. Move logic not specific to your application's domain to reusable middlewares to save time and effort. Harness the synergy of server and framework agnostic solutions to common challenges.
HTTP friendly
Fail early with the semantically correct HTTP response status code when certain conditions are not satisfied, such as when the request has an unexpected HTTP method or media-type. Built-in automatic but overrideable handling of OPTIONS requests.
Extensible
Vinland is built on the Raven router. Define your own sub-protocols as needed, or dispatch to bare Clack handlers when performance is critical.
Familiar
Ships with a plethora of macros and functions to save you keystrokes and minimize HTTP-related shenanigans in your route handlers. Access request parameters, set flash messages, render views, set and remove cookies and session data, perform redirects and content-negotiation, all out-of-the-box.
Minimalistic
Provides some structure and then gets out of your way. Bring your own database and HTML generator.
