def apply[F[_]](run: Request[F] => F[Response[F]])(implicit evidence$1: Monad[F]): HttpApp[F]

Lifts a function into an HttpApp. The application of run is suspended in F to permit more efficient combination of routes via SemigroupK.

Type Params
F

the effect of the HttpApp.

Value Params
run

the function to lift

Returns

an HttpApp that wraps run

def liftF[F[_]](fr: F[Response[F]]): HttpApp[F]

Lifts an effectful Response into an HttpApp.

Type Params
F

the effect of the HttpApp

Value Params
fr

the effectful Response to lift

Returns

an HttpApp that always returns fr

def local[F[_]](f: Request[F] => Request[F])(fa: HttpApp[F])(implicit F: Monad[F]): HttpApp[F]

Transforms an HttpApp on its input. The application of the transformed function is suspended in F to permit more efficient combination of routes via SemigroupK.
