import Miso

data IntAction = Add | Subtract

intView :: Int -> View IntAction
intView n = div_ [ class_ "main" ] [
   btn_ [ onClick Add ] [ text_ "+" ]
 , text_ $ pack (show n)
 , btn_ [ onClick Subtract ] [ text_ "-" ]
 ]

Core types and interface

data VTree action where Source #

Virtual DOM implemented as a Rose Vector. Used for diffing, patching and event delegation. Not meant to be constructed directly, see View instead.

Constructors

Fields vType :: Text Element type (i.e. "div", "a", "p") vNs :: NS HTML or SVG vProps :: Props Fields present on DOM Node vKey :: Maybe Key Key used for child swap patch vChildren :: Vector (VTree action) Child nodes
VText :: {..} -> VTree action
Fields vText :: Text TextNode content

Setting properties on virtual DOM nodes

prop :: ToJSON a => MisoString -> a -> Attribute action Source #

Constructs a property on a VNode, used to set fields on a DOM Node

Setting CSS

style_ :: Map MisoString MisoString -> Attribute action Source #

Constructs CSS for a DOM Element

import qualified Data.Map as M
div_ [ style_  $ M.singleton "background" "red" ] [ ]
