Skill: UI Component Library

Purpose: Catalog of ready-to-use HTML/CSS/JS components for dashboard projects. Insert components directly — no reinventing each time. When: Building a dashboard, admin panel, or monitoring UI in plain HTML/CSS/Jinja2. Output: Ready CSS + HTML markup + formulas for each component.

11. Relative Time (JS)

function timeAgo(iso) {
  if (!iso) return '—';
  const s = iso.replace(' ', 'T');
  const n = /[Zz]$|[+-]\d\d:\d\d$/.test(s) ? s : s + 'Z';
  const d = Math.floor((Date.now() - new Date(n)) / 1000);
  if (isNaN(d) || d < 0) return iso.slice(0, 16);
  if (d < 60)    return d + 's';
  if (d < 3600)  return Math.floor(d / 60) + 'm';
  if (d < 86400) return Math.floor(d / 3600) + 'h';
  return Math.floor(d / 86400) + 'd';
}
// Apply to all .time-ago[data-ts] elements:
document.querySelectorAll('.time-ago[data-ts]').forEach(el => {
  if (el.dataset.ts) el.textContent = timeAgo(el.dataset.ts);
});

12. Lazy Wallet Name Loading (JS)

// Requires /api/wallet-name/{addr} endpoint returning {name: string|null}
async function loadNames() {
  const links = document.querySelectorAll('.wallet-link[data-addr]');
  for (const el of links) {
    if (el.querySelector('.wallet-name')) continue;
    try {
      const r = await fetch(`/api/wallet-name/${el.dataset.addr}`);
      if (!r.ok) continue;
      const d = await r.json();
      if (d.name) el.innerHTML = `<span class="wallet-name" style="font-weight:600">${d.name}</span>`;
    } catch {}
    await new Promise(r => setTimeout(r, 400)); // rate limit: 400ms between requests
  }
}
loadNames();

Note: if .wallet-link has other child elements (flags ⚑, address), preserve them before overwrite: check el.innerHTML.includes('⚑') before replacement.
