Features

4. The super-what ?
• This is the ethos the team is striving for, but here are the basic ideas behind
it :
– It just works – little to no configuration even when adding modules, viewengines,
dependencies, etc.
– Easily customisable – possibility to redefine each pieces of the frameworks
– Low ceremony – minimal amount of « Nancy code », focus is on the application
code
– Low friction – easy usage of the framework without sacrificing extensibility and
power when you need it

5. • Define the behavior of your application
• Must inherit NancyModule and are globally discovered

Modules

6. • A lot of common things with ASP.NET MVC routing
• Main differencies :
– Defined in a module constructor
– Each capturing segment pattern has a score
– The route which has the best score (combining all the matching segments
scores) has the priority
– The order of route loading is not important unless two matching routes have the
same score

Routing

7. • Aggregate all the framework pieces together
• Responsible of the automatic discovery of modules, model binders,
dependencies, etc.
• Built on top of a IoC container (TinyIoc)
• Can be replaced with another container (already available : ninject,
structuremap, unity and more)
• Can be overrided to change or add features

Bootstrapper

8. • Takes a “template” and an optional “model” and usually render HTML
• Shipped with the SuperSimpleViewEngine (.html and .sshtml files) but can
be replaced
• Just adding a reference to them via the separate nuget package will make
them available
• Possibility to implement your own view engine and hook it up like any other
