React Transition Group
React Transition Group is a library for managing component transitions and animations in React applications. It provides a set of components that expose lifecycle hooks for entering and exiting transitions, allowing developers to implement CSS or JavaScript-based animations without directly manipulating the DOM. It is commonly used for adding smooth fade-ins, slide-outs, and other visual effects when components mount or unmount.
Developers should use React Transition Group when they need to implement controlled, declarative animations for component mounting/unmounting or state changes in React, especially for UI elements like modals, tooltips, or list items. It is ideal for scenarios where you want to add transitions without heavy animation libraries, as it integrates seamlessly with React's component lifecycle and works well with CSS transitions or libraries like React Spring. Use it to enhance user experience with smooth visual feedback in single-page applications.
