Overview

React on Screen is an elegant solution for tracking the visibility of React components on the screen, designed with performance in mind. This library helps streamline the process of lazy loading images or components based on their presence in the viewport, ensuring smooth user experiences without unnecessary re-renders or performance hitches.

The powerful features it offers, such as customizable visibility tracking and flexible API options, allow developers to tailor the component's behavior to meet specific project needs. Whether you want to trigger functionalities based on visibility or optimize resource loading, React on Screen provides the tools necessary for effective implementation.

Features

  • Visibility Tracking: Effortlessly track whether your React components are visible on the screen with an option to monitor visibility only once, reducing overhead.
  • Render Props Support: Utilize render props to create highly reusable and dynamically controlled components for various visibility scenarios.
  • Offset Configuration: Easily set an offset to determine how far above or below the viewport components need to be for visibility to be triggered, perfect for optimizing lazy loading.
  • Partial Visibility Recognition: Optionally treat components as visible when any part of them is within the viewport, making it easier to load components gradually.
  • Custom HTML Tags: Choose any HTML tag for wrapping your components, offering flexibility in implementation according to your styling or structural requirements.
  • Lightweight: Designed with performance in mind, reducing unnecessary renders and optimizing resource usage for a smoother user experience.
  • Easy Installation: Simple setup instructions with UMD build availability make integrating this library into projects straightforward and hassle-free.
  • Community Contributions: Actively encourages developer contributions, fostering an open-source spirit and continual improvement of the library.
