uni-dom Feature Ideas

Tracking feature suggestions for expanding uni-dom's browser API coverage.

High Value — Commonly needed in real apps

• Element Transitions — Enter/exit/move animations for elements (like Vue's <Transition> / <TransitionGroup>). Declarative CSS transition orchestration.
• Click Outside Detection — Detect clicks outside an element (essential for dropdowns, modals, popovers).
• Virtual Scroll / Windowing — Efficiently render large lists by only mounting visible items. Builds on IntersectionObserver + ResizeObserver.
• Idle Detection — requestIdleCallback wrapper for deferring non-critical work, plus user inactivity detection.
• Debounce / Throttle utilities — Generic Rx-level debounce/throttle for input events.

Medium Value — Useful for richer apps

• WebSocket client — Reactive WebSocket wrapper (Rx[Message], auto-reconnect, backoff).
• Fullscreen API — Enter/exit fullscreen with reactive state tracking.
• Web Share API — Native share sheet with fallback detection.
• Selection API — Track text selection ranges reactively.
• Canvas 2D wrapper — Declarative canvas drawing context.

Lower Priority — Niche but nice to have

• MutationObserver bindings — Watch DOM subtree changes reactively.
• Permission API — Query and watch browser permission states.
• Page Lifecycle — Freeze/resume detection beyond just visibility.
• IndexedDB wrapper — Reactive client-side database for larger/structured data.
