data VDom :: Type -> Type

Instances

• Functor VDom

data Prop :: Type -> Type

data Sub :: Type -> Type

h :: forall msg. String -> Array (Prop msg) -> Array (VDom msg) -> VDom msg

h tag attributes children

text :: forall msg. String -> VDom msg

create a text virtual node

emptyNode :: forall msg. VDom msg

represent an empty virtual node

does not generate HTML content. Only used for commodity

key :: forall msg. String -> Prop msg

add a key to the vnode

attr :: forall msg. String -> String -> Prop msg

add or change an attribute

style :: forall msg. String -> String -> Prop msg

add or change a style attribute

on_ :: forall msg. String -> (Event -> Maybe msg) -> Prop msg

class_ :: forall msg. String -> Prop msg

add a class name to the vnode

class' :: forall msg. String -> Boolean -> Prop msg

add a class name to the vnode if the second argument is true

memo :: forall msg a. a -> (a -> VDom msg) -> VDom msg

lazily generate a virtual dom

i.e. generate only if the first argument has changed. otherwise, return the previous generated virtual dom

when :: forall msg. Boolean -> (Unit -> VDom msg) -> VDom msg

when true = vdom unit
when false = emptyNode

Operator alias for Pha.when (non-associative / precedence 1)

maybeN :: forall msg. Maybe (VDom msg) -> VDom msg

maybeN (Just vdom) = vdom
maybeN Nothing = emptyNode

maybe :: forall msg a. Maybe a -> (a -> VDom msg) -> VDom msg

Operator alias for Pha.maybe (non-associative / precedence 1)

unsafeOnWithEffect :: forall msg. String -> EventHandler msg -> Prop msg

type EventHandler msg = Event -> { effect :: Effect Unit, msg :: Maybe msg }

the effect can be stopPropagation, preventDefault, releasePointerCapture, etc...

Operator alias for Data.Tuple.Tuple (right-associative / precedence 6)

Shorthand for constructing n-tuples as nested pairs. a /\ b /\ c /\ d /\ unit becomes Tuple a (Tuple b (Tuple c (Tuple d unit)))

type Update st effs = Run (state :: STATE st | effs) Unit

data Event :: Type

Basic type for all DOM events.
