Running your application

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

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 ()Source

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

Utilities

Hamlet

type HtmlUrl url = Render url -> Html

A function generating an Html given a URL-rendering function.

type Html = Markup

toHtml :: ToMarkup a => a -> Markup

Julius

type JavascriptUrl url = (url -> [(Text, Text)] -> Text) -> Javascript

Return type of template-reading functions.

renderJavascriptUrl :: (url -> [(Text, Text)] -> Text) -> JavascriptUrl url -> Text

render with route interpolation. If using this module standalone, apart from type-safe routes, a dummy renderer can be used:

 renderJavascriptUrl (\_ _ -> undefined) javascriptUrl

When using Yesod, a renderer is generated for you, which can be accessed within the GHandler monad: getUrlRenderParams.
