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.
-
TransitionGroup
andCSSTransitionGroup
, for dealing with animations and transitions that are usually not simple to implement, such as before a component's removal. -
LinkedStateMixin
, to simplify the coordination between user's form input data and the component's state. -
cloneWithProps
, to make shallow copies of React components and change their props. -
createFragment
, to create a set of externally-keyed children. -
update
, a helper function that makes dealing with immutable data in JavaScript easier. -
PureRenderMixin
, a performance booster under certain situations. -
shallowCompare
, a helper function that performs a shallow comparison for props and state in a component to decide if a component should update.
The add-ons below are in the development (unminified) version of React only:
-
TestUtils
, simple helpers for writing test cases. -
Perf
, a performance profiling tool for finding optimization opportunities.
To get the add-ons, install them individually from npm (e.g., npm install react-addons-pure-render-mixin
). We don't support using the addons if you're not using npm.
