Running JSM over WebSockets
Functions used to implement JSaddle over WebSockets

Description

Synopsis

Running JSM over WebSockets

run :: Int -> JSM () -> IO () Source #

Run the given JSM action as the main entry point. Either directly in GHCJS or as a Warp server on the given port on GHC.

syncPoint :: JSM () Source #

Forces execution of pending asyncronous code

syncAfter :: JSM a -> JSM a Source #

Forces execution of pending asyncronous code after performing f

waitForAnimationFrame :: JSM Double Source #

On GHCJS this is waitForAnimationFrame. On GHC it will delay the execution of the current batch of asynchronous command when they are sent to JavaScript. It will not delay the Haskell code execution. The time returned will be based on the Haskell clock (not the JavaScript clock).

nextAnimationFrame :: (Double -> JSM a) -> JSM a Source #

Tries to executes the given code in the next animation frame callback. Avoid synchronous opperations where possible.

jsaddleOr :: ConnectionOptions -> JSM () -> Application -> Application Source #
