Preact port of the new react-transition-group ?

[tzvc]

Hi there, love what you are doing with Preact, it's awesome ! ;)

I've been searching for the equivalent of the new https://github.com/reactjs/react-transition-group in Preact.

Is this what this is supposed to be ? If yes what is the equivalent of the CSSTransition component ?

Thanks !

As I see, there is no CSSTransition class exported in preact-transition-group

@theochampion @vinaybedre FYI, I've begun a rewrite of this package based on the new v2 react-transition-group which includes the CSSTransition component. A PR should be out in the (hopefully) near future.

@andrewiggins any progress?

[andrewiggins]

Yes! I've gotten a good amount of the work done in my andrewiggins/preact-transition-group refork-v2 branch. Still working through fixing all the tests.

@andrewiggins any chance you can port this over to preact-x? thanks!

@andrewiggins i have converted the latest react-transition-group to work with preact X. it wasn't that much work, but i've struggled with a couple of the tests. 13 out of 54 still fail. it's fully functional now as far as i can tell, but i think i'm gonna need some help bringing it over the finish line. if you guys are interested that is.

i've pushed my changes to the preact branch in a forked repo, https://github.com/lohfu/react-transition-group/tree/preact

regarding the tests, i think most of the problems stem from inconsistencies in the react and preact adapters for enzyme, but i'm not 100% sure. i bet if you have a look you'll solve most of them in a jiffy.

EDIT
the only test file i have not touched yet is, https://github.com/lohfu/react-transition-group/blob/preact/test/CSSTransitionGroup-test.js. i let it be because almost all tests depended on the render function returning returning a VNode. i have never used enzyme before this, nor do i know any of the inner workings of preact or react so i felt it was best to leave it completely untouched so someone with more skillz can see what the react peeps intended the tests to do.
