Building Lightweight Scroll Effects in React

Scroll effects are fundamental to modern web interfaces, yet developers typically resort to heavy animation libraries or error-prone imperative code to implement them correctly in React. This guide introduces ReactUse, an open-source collection of 100+ React hooks designed to simplify common scroll scenarios—from tracking position and locking scrolls to detecting intersections and sticky elements—all without external dependencies. By leveraging purpose-built hooks, developers can build more maintainable, performant scroll interactions with SSR-safe composable APIs.
