A Vue.js component that traps keyboard focus within modal dialogs and focused tasks for accessibility compliance.
vue-focus-lock is a Vue.js component that traps keyboard focus within a specific DOM element, preventing users from tabbing outside modal dialogs or focused interfaces. It solves the accessibility problem of managing keyboard focus in modal contexts, which is required for WAI-ARIA compliant dialogs.
Vue.js developers building accessible modal dialogs, focused task interfaces, or any component requiring strict keyboard focus management for accessibility compliance.
Developers choose vue-focus-lock because it provides reliable, browser-native focus trapping without altering standard tabbing behavior, has minimal API surface, and is specifically designed for Vue.js applications with support for both Vue 2 and Vue 3.
It is a trap! A lock for a Focus. A11y util for scoping a focus.

Uses browser-native focus methods instead of emulation, ensuring predictable tab cycling and compatibility with standard keyboard behavior, as stated in the README.
Offers minimal props like disabled, group, and noFocusGuards, making it straightforward to integrate without overwhelming configuration, as shown in the usage examples.
Gracefully handles multiple locks by only activating the deepest or last one, preventing conflicts in complex UI layers, which is explicitly documented.
Properly manages elements with positive tabIndex values, ensuring correct focus order in custom tab sequences, a key feature highlighted in the README.
Does not automatically return focus to the original element when the lock is disabled, requiring additional manual code for better user experience, as admitted in the README.
Limited to Vue.js ecosystems (Vue 2 or 3), making it unsuitable for projects using React, Angular, or other frameworks without workarounds.
Relies on virtual focus guards to prevent page scrolling; disabling them (e.g., with noFocusGuards prop) can introduce accessibility issues if not carefully managed.
Focuses primarily on focus trapping without built-in support for advanced scenarios like focus management across shadow DOM or custom focus events, which may require extra development.
