Description

Simple utilities for embedding a monad transformer stack in an Application or Middleware - with MiddlewareT, your transformer stack is shared across all attached middlewares until run. You can also lift existing Middleware to MiddlewareT, given some extraction function.

Documentation

type ApplicationT m = Request -> (Response -> IO ResponseReceived) -> m ResponseReceived Source

type MiddlewareT m = ApplicationT m -> ApplicationT m Source

liftApplication :: MonadIO m => Application -> ApplicationT m Source

liftMiddleware :: MonadIO m => (ApplicationT m -> Application) -> Middleware -> MiddlewareT m Source

runApplicationT :: (forall a. m a -> IO a) -> ApplicationT m -> Application Source

runMiddlewareT :: MonadIO m => (forall a. m a -> IO a) -> MiddlewareT m -> Middleware Source
