|
|
--
|
|
-- * Creates the route datatype AppRoute. Every valid URL in your
|

-- application can be represented as a value of this type.
|
|
-- * Creates the associated type:
|
|
-- type instance Route App = AppRoute
|
|
-- * Creates the value resourcesApp which contains information on the
|
|
-- resources declared below. This is used in Handler.hs by the call to
|
|

|
|
-- What this function does *not* do is create a YesodSite instance for
|
|
-- App. Creating that instance requires all of the handler functions
|
|
-- for our application to be in scope. However, the handler functions
|
|
-- usually require access to the AppRoute datatype. Therefore, we
|
|
-- split these actions into two functions and place them in separate files.
