Fluent UI Web

Fluent UI React is shipping its v9 final stable release. Visit the Fluent UI React v9 Release page on the wiki to learn more about the upcoming release schedule.

Fluent UI web represents a collection of utilities, React components, and Web Components for building web applications.

This repo is home to 3 separate projects today. Combining Fluent UI React v9 components with Fluent UI React v8 or v0 components is possible and allows gradual migration to Fluent UI v9.

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.
