TEA Combine

A set of combinators for working with stateful (and effectful) components.

Using this library you can do this:

import Browser
import CheckBox
import Counter
import Html
import TeaCombine exposing (..)
import TeaCombine.Pure.Pair exposing (..)


main =
    Browser.sandbox
        { init =
            Counter.init 0
                |> initWith (CheckBox.init False)
                |> initWith (CheckBox.init False)
        , view =
            Html.div []
                << (joinViews Counter.view CheckBox.view
                        |> withView CheckBox.view
                   )
        , update =
            Counter.update
                |> updateWith CheckBox.update
                |> updateWith CheckBox.update
        }

and have an app that looks like this (image is clickable!):

Here you can find a good explanatory article (thanks to Maldus512!) about how all this stuff works!

(All the sources you can find here)

• simple one with Pure combinators,
• another pure but recursive,
• one with Effectful combinators,
• another effectful but recursive,
• one with form & binding,
• one with multi-page layout,
• another multi-page one but with the state resetting on tab switch.
