zwilias / elm-html-string / Html.String.Lazy

🔥 This isn't actually lazy in this library..

.. because we can't keep track of the model without existential types. It just eagerly evaluates. This set of function is here to serve as a drop-in replacement.

lazy : (a -> Html.String.Html msg) -> a -> Html.String.Html msg

A performance optimization that delays the building of virtual DOM nodes.

Calling (view model) will definitely build some virtual DOM, perhaps a lot of it. Calling (lazy view model) delays the call until later. During diffing, we can check to see if model is referentially equal to the previous value used, and if so, we just stop. No need to build up the tree structure and diff it, we know if the input to view is the same, the output must be the same!

lazy2 : (a -> b -> Html.String.Html msg) -> a -> b -> Html.String.Html msg

Same as lazy but checks on two arguments.

lazy3 : (a -> b -> c -> Html.String.Html msg) -> a -> b -> c -> Html.String.Html msg

Same as lazy but checks on three arguments.

lazy4 : (a -> b -> c -> Html.String.Html msg) -> a -> b -> c -> Html.String.Html msg

Same as lazy but checks on four arguments.

lazy5 : (a -> b -> c -> Html.String.Html msg) -> a -> b -> c -> Html.String.Html msg

Same as lazy but checks on five arguments.

lazy6 : (a -> b -> c -> Html.String.Html msg) -> a -> b -> c -> Html.String.Html msg

Same as lazy but checks on six arguments.

lazy7 : (a -> b -> c -> Html.String.Html msg) -> a -> b -> c -> Html.String.Html msg

Same as lazy but checks on seven arguments.

lazy8 : (a -> b -> c -> Html.String.Html msg) -> a -> b -> c -> Html.String.Html msg

Same as lazy but checks on eight arguments.
