Add-Ons

Note:

React.addons entry point is deprecated as of React v15.5. The add-ons have moved to separate modules, and some of them have been deprecated.

The React add-ons are a collection of useful utility modules for building React apps. These should be considered experimental and tend to change more often than the core.

• createFragment, to create a set of externally-keyed children.

The add-ons below are in the development (unminified) version of React only:

• Perf, a performance profiling tool for finding optimization opportunities.
• ReactTestUtils, simple helpers for writing test cases.
