data Component :: Type -> Type -> Type

Instances

• Functor (Component a)
• Apply (Component a)
• Bind (Component a)

runComponent :: forall o a. String -> Component a o -> Effect Unit

modelView :: forall p o a. (o -> Now p) -> (p -> Component a o) -> Component p (Record ())

merge :: forall q p b o a. Union o p q => Component a (Record o) -> Component b (Record p) -> Component (Record ()) (Record q)

Combines two components and merges their selected output.

Operator alias for Turbine.merge (left-associative / precedence 0)

dynamic :: forall o a. Behavior (Component a o) -> Component (Behavior o) (Record ())

Turns a behavior of a component into a component of a behavior. This function is used to create dynamic HTML where the structure of the HTML should change over time.

dynamic (map (\b -> if b else (div {} ) then) behavior)

use :: forall q p o a. Union o p q => Component a (Record o) -> (a -> Record p) -> Component (Record ()) (Record q)

Copies non-selected output into selected output.

This function is often used in infix form as in the following example.

button (text "Fire missiles!") `use` (\o -> { fireMissiles })

component :: forall p o a. (o -> Now (ComponentResult a o p)) -> Component p (Record ())

type ComponentResult a o p = { available :: p, component :: Component a o }

output :: forall f p o a. Applicative f => Component a o -> p -> f (ComponentResult a o p)

class Key a  where

Type class implemented by Int, Number, and String. Used to represent overloads.

Instances

• MapRecord Nil row f () ()

static :: forall row c a. RowToList row c => MapRecord c row Behavior () a => Record row -> Record a

A helper function used to convert static values in records into constant behaviors.

Component functions often takes a large amount of behaviors as input. But, sometimes all that is required is static values, that is, constant behaviors. In these cases it can sometimes be tedious to write records like the following:

{ foo: pure 1, bar: pure 2, baz: pure 3, more: pure 4, fields: pure 5 }

The static function applies pure to each value in the given record. As such, the above can be shortened into the following.

static { foo: 1, bar: 2, baz: 3, more: 4, fields: 5 }

withStatic :: forall xs p' q' q p o. RowToList p xs => MapRecord xs p Behavior () p' => Union o p' q' => Nub q' q => Record o -> Record p -> Record q

A function closely related to static. Usefull in cases where a component function is to be supplied with both a set of static values (constant behaviors). The function applies static to its seconds argument and merges the two records.

It is often used in infix form as in the following example.

{ foo: behA, bar: behB } `withStatic` { baz: 3, more: 4, fields: 5 }
