Focus Trap React
A React component that traps focus
Overview
If you're developing accessible web applications with React, the Focus Trap component is an essential tool that can significantly enhance user experience. This lightweight wrapper around the focus-trap library allows developers to manage focus within specific areas of the application, ensuring that keyboard navigation remains intuitive and accessible. Ideal for creating modal dialogs or interactive features, the component captures focus strictly within its boundaries, preventing users from navigating away unintentionally.
Designed specifically for React, this library leverages modern features and is compatible with React 18 and beyond. By streamlining the focus management process, it helps UX designers create accessible experiences that cater to all users, especially those relying on keyboard navigation.
Features
- Automatic Focus Activation: The focus trap automatically activates when the component mounts, offering an effortless setup for developers.
- Easy Deactivation: Upon unmounting, the focus trap deactivates automatically, ensuring a hassle-free user experience.
- Control Over Focus Behavior: Developers can pause, unpause, activate, and deactivate the focus trap as needed via props, providing flexibility for dynamic interfaces.
- Compatibility with React 18: The component is designed for use with React 18.0.0 and higher, ensuring future-proof integration with newer features and optimizations.
- Browser Support: Focus-trap-react focuses on major desktop browsers like Chrome, Firefox, and Safari, catering primarily to desktop users while keeping performance in mind.
- Single Child Element: The <FocusTrap> component expects a single child, which can be any HTML or React element, emphasizing simplicity in implementation.
- No Fragment Support: The component does not support Fragments, as it requires a direct reference to the underlying HTML element for proper functionality.
- Static and Runtime Type Validation: With the deprecation of propTypes, users are encouraged to utilize TypeScript or validation libraries for ensuring type safety within their applications.
- React
React is a widely used JavaScript library for building user interfaces and single-page applications. It follows a component-based architecture and uses a virtual DOM to efficiently update and render UI components
- Eslint
ESLint is a linter for JavaScript that analyzes code to detect and report on potential problems and errors, as well as enforce consistent code style and best practices, helping developers to write cleaner, more maintainable code.
- Typescript
TypeScript is a superset of JavaScript, providing optional static typing, classes, interfaces, and other features that help developers write more maintainable and scalable code. TypeScript's static typing system can catch errors at compile-time, making it easier to build and maintain large applications.
