A React component library that detects when its wrapped element enters or leaves the browser viewport and fires an onChange callback. It supports partial visibility, pixel offsets, and interval-based checks.

Use cases

  • trigger animations when a component scrolls into view
  • lazy-load images when they become visible
  • track how long content is visible to users
  • pause videos when scrolled out of the viewport
  • fire analytics events on element visibility
  • detect partial visibility of elements during scrolling

When to choose

  • you need viewport visibility detection in a React app with fine-grained control over offsets and partial visibility
  • you need to support older browsers or React versions where IntersectionObserver-based hooks are not viable

When to avoid

  • you are using a modern stack where the native IntersectionObserver API or a hook like react-intersection-observer suffices
  • your project is not React-based
  • you need visibility detection outside the browser (e.g., server-side or native apps)
