Looking for Office UI Fabric React?
The Office UI Fabric React project has evolved to Fluent UI.
The office-ui-fabric-react repo is now this repo (fluentui in the Microsoft organization)! The name change should not disrupt any current Fabric usage, repo clones, pull requests, or issue reporting. Links should redirect to the new location. The library formerly known as office-ui-fabric-react is now available as @fluentui/react (see above table for more information).
We have a lot in store for Fluent UI - Read our announcement here.
