data Options Source

Constructors

Options
Fields verbose :: Int 0 = silent, 1(def) = startup banner settings :: Settings Warp `Settings` Note: to work around an issue in warp, the default FD cache duration is set to 0 so changes to static files are always picked up. This likely has performance implications, so you may want to modify this for production servers using `setFdCacheDuration`.

Instances

Default Options

type Middleware m = Application m -> Application m Source

type Application m = Request -> m Response Source

data ScottyState e m Source

Constructors

ScottyState
Fields middlewares :: [Middleware] routes :: [Middleware m] handler :: ErrorHandler e m

Instances

Monad m => Default (ScottyState e m)

addMiddleware :: Middleware -> ScottyState e m -> ScottyState e m Source

addRoute :: Monad m => Middleware m -> ScottyState e m -> ScottyState e m Source

addHandler :: ErrorHandler e m -> ScottyState e m -> ScottyState e m Source

newtype ScottyT e m a Source

Constructors

ScottyT
Fields runS :: StateT (ScottyState e m) m a

Instances

MonadTrans (ScottyT e)
Monad m => Monad (ScottyT e m)
Functor m => Functor (ScottyT e m)
(Monad m, Functor m) => Applicative (ScottyT e m)
MonadIO m => MonadIO (ScottyT e m)

data ActionError e Source

Constructors

Redirect Text
Next
ActionError e

Instances

ScottyError e => Error (ActionError e)
ScottyError e => ScottyError (ActionError e)
(ScottyError e, Monad m) => MonadError (ActionError e) (ActionT e m)

class ScottyError e where Source

In order to use a custom exception type (aside from Text), you must define an instance of ScottyError for that type.
