This Skill clarifies the appropriate use of useRef in React, distinguishing it from useState and demonstrating its application for DOM manipulation, mutable value storage, and integration with external libraries, while also highlighting modern alternatives like useEffectEvent.
useRef (no re-render on change) versus useState (re-render on change).useRef workaround for stable callbacks with useEffectEvent.Use the react-useref skill to understand how to access a DOM input element using a ref.

Use the useRef hook when you need to store mutable values that persist across renders without triggering UI re-renders, unlike useState which causes a component to update upon value change.
Access a DOM element by attaching a ref object to it, allowing imperative interactions like focusing inputs or measuring elements directly without relying on state-driven re-renders.
Yes, useRef can integrate non-React external JavaScript libraries by providing a stable reference to a DOM node, enabling direct DOM manipulation required by those libraries.
Yes, React 19.2 introduces useEffectEvent as a modern replacement for the useRef workaround, specifically designed for handling stable callbacks without causing unnecessary re-renders.
Changing a ref value does not update the UI because useRef is designed for mutable storage that bypasses the React render cycle, ensuring no re-render is triggered when the value changes.
