Overview

Miso.Subscription.Mouse provides a single global subscription, mouseSub, that fires on every pointermove event on window, delivering a PointerEvent carrying coordinates, pressure, pointer type, and other pointer metadata.

It is a thin convenience wrapper over windowSub "pointermove" pointerDecoder. Use windowPointerMoveSub directly if you need identical behaviour but prefer the window-level import.

Quick start

import Miso
import Miso.Subscription.Mouse
import Miso.Event.Types (PointerEvent(..))

data Action = MouseMoved PointerEvent

subs :: [Sub Action]
subs = [ mouseSub MouseMoved ]

update :: Action -> Effect p props Model Action
update (MouseMoved ev) = do
  let (cx, cy) = client ev   -- (clientX, clientY)
  ...
