CompileTemplateOnce

Compile a template once

Mostly useful if you are only inserting URLs and no variables. Any variables will only be rendered once. This example is using coffeescript.

defaultLayout widget = do
  y <- getYesod
  mroute <- liftIO $ readIORef $ staticRenders y
  coffeeUrl <- case mroute of
      Just r -> return r
      Nothing -> do
        renderUrl <- getUrlRenderParams
        c <- liftIO $ renderCoffee renderUrl $(Settings.coffeeFile "search")
        Just (Right (u, p)) <- addStaticContent "js" "text/javascript; charset=utf-8"
                                  $ encodeUtf8 c
        let r = renderUrl u p 
        liftIO $ writeIORef (staticRenders y) (Just r)
        return r
