Running your application

warp :: (Yesod a, YesodDispatch a a) => Int -> a -> IO ()

A convenience method to run an application using the Warp webserver on the specified port. Automatically calls toWaiApp.

warpDebug :: (Yesod a, YesodDispatch a a) => Int -> a -> IO ()

Same as warp, but also sends a message to stderr for each request, and an "application launched" message as well. Can be useful for development.

develServer

Arguments

:: Int

port number

-> String

module name holding the code

-> String

name of function providing a with-application

-> IO ()

Run a development server, where your code changes are automatically reloaded.

Commonly referenced functions/datatypes

type Application = Request -> Iteratee ByteString IO Response

lift :: MonadTrans t => forall m a. Monad m => m a -> t m a

Lift a computation from the argument monad to the constructed monad.

liftIO :: MonadIO m => forall a. IO a -> m a

Lift a computation from the IO monad.

class MonadIO m => MonadPeelIO m

MonadPeelIO is the class of IO-based monads supporting an extra operation peelIO, enabling control operations on IO to be lifted into the monad.
