Pull to Refresh

A phone-frame mockup with draggable list rows; pulling down reveals a teal arc spinner that fills and rotates, then triggers a skeleton-row flash on release.

When to use it

Demoing mobile pull-to-refresh patterns, onboarding flows showing gesture affordances, or UI kit showcases.

When not to

Production refresh logic — the auto-cycle timer and demo frame must be removed; also skip in contexts where cursor/touch drag conflicts with page scroll.

Working with an AI agent

Every component ships agent-ready metadata. An example instruction for this one:

Change the spinner color from teal (#3ad6c5) to coral (#ff6b6b), increase MAX pull distance to 90, and slow the auto-cycle timer from 2400ms to 4000ms. Theme: dark tokens live in :root, the light variant in :root[data-theme="light"]; ?theme=light or a {type:'forever:theme'} postMessage switches at runtime.

Safe to edit

  • MAX pull distance (MAX=60)
  • spinner stroke color (#3ad6c5)
  • auto-cycle delay (2400ms)
  • row count (7)
  • refresh spin duration (700ms / 1400ms)
  • ease duration (260ms)
  • theme tokens (:root dark defaults + [data-theme=light] overrides)

Keep intact

  • visibilitychange pause + clearTimeout guard
  • prefers-reduced-motion guard (reduce check stops auto-loop)
  • touch/mouse unified event handlers
  • IIFE-less but scoped const declarations
  • theme hook (?theme= bootstrap + forever:theme message listener + theme tokens)

Known limitations

  • touchmove is passive:true so calling preventDefault to block page scroll is not possible — may conflict with scrollable parent containers
  • No aria roles on draggable area — needs role=button or gesture instructions for screen readers in production
  • Auto-cycles indefinitely — remove loop() call and timer for production use
