Elm Transit Style

elm package install etaque/elm-transit-style

Animations for elm-transit, to be used on elm-html style attribute. At the moment we have those, though it's easy to add more:

• fade
• slideLeft
• fadeSlideLeft

How it works

A transition is composed of two phases: Exit then Enter. A style for a phase can be constructed with this signature:

Float -> Style

Where the Float is the clock of transition phase, varying from 0 to 1. A Style is just an alias to List (String, String).

A complete transition animation is constructed by composing exit and enter animations on a transition:

compose : (Float -> Style) -> (Float -> Style) -> Transition -> Style

It can then be used on a transition. Example for fade and left slide animation, with a 50px offset:

  div
    [ style (TransitStyle.fadeSlideLeft 100 model.transition) ]
    [ text "Some content" ]
