React Activity Component Explained (Finally Makes Sense!)

Welcome to Shade Tech! 🚀👨‍💻 The React Activity component, introduced in React 19.2, is designed to hide parts of the UI while preserving their state, effectively allowing components to be "put to sleep" without losing their internal data or DOM state. This solves a common problem where traditional conditional rendering or CSS-based hiding would either unmount components (destroying state) or keep effects running unnecessarily. The component operates with two primary modes: visible and hidden. When set to visible, the component renders normally with full priority, mounting all effects and remaining interactive. When set to hidden, the component remains in the React fiber tree and DOM, but its rendering is deprioritized, and all active effects are unmounted and cleaned up. This allows for background pre-rendering of components that a user is likely to navigate to next, improving perceived performance by loading assets like images and styles in advance. - Join Channel Community :- https://discord.gg/RkCyxHAYMv Article - https://dev.to/sh20raj/what-is-activity-in-react-3foh Codes - https://github.com/SH20RAJ/performance-gain/tree/react/activity React ref. - https://react.dev/reference/react/Activity https://www.youtube.com/playlist?list=PLfAV8wPWROFBcGVsM4trc26eVtIC7epX5 🌟 About This Video:
