Cannot resolve module 'preact-compat/lib/ReactTransitionGroup' & module ReactFragment

I'm trying to convert an existing React application based on Material-UI http://www.material-ui.com/ and receive the following errors during the build process:

ERROR in .//react-addons-transition-group/index.js
Module not found: Error: Cannot resolve module 'preact-compat/lib/ReactTransitionGroup' in c:\code\TDC\preact\node_modules\react-addons-transition-group
@ .//react-addons-transition-group/index.js 1:17-58

ERROR in .//react-addons-create-fragment/index.js
Module not found: Error: Cannot resolve module 'preact-compat/lib/ReactFragment' in c:\code\TDC\preact\node_modules\react-addons-create-fragment
@ .//react-addons-create-fragment/index.js 1:17-51

Is this something that is common working with controls built for React?

Hi @struckm!

For the CSSTransitionGroup you should just be able to alias it to preact-css-transition-group.

For CreateFragment, I actually haven't encountered that one yet! I'll take a look at what it does, likely just something we need to shim.

Thanks for the quick response, the alias worked for transition group but fragment is still an issue. I'm looking at pulling Material-UI out of the project in favor of Material Design Lite since those are already Preact components. Also, I would like to remove preact-compat from the project.

That's a good goal, and it should dramatically reduce the size of your application. Feel free to drop into Gitter if you run into anything on the way!
