  • Samhitā Pāṭha with Vedic accent marks (Udātta ॑, Anudātta ॒)
  • Toggle Pada Pāṭha alongside the Samhitā text
  • Navigate by Maṇḍala/Sūkta or Aṣṭaka/Adhyāya/Varga — switch modes freely
  • Tap any mantra text or ref to copy it to clipboard; long-press on mobile

Search

  • Search in Devanāgarī script or Roman transliteration
  • Three-tier matching: exact → space-insensitive compact → fuzzy (Levenshtein)
  • Filter results by Maṇḍala, Aṣṭaka, or Adhyāya
  • Click any search result to jump directly to it in context

Offline / PWA

  • Installable as a Progressive Web App on Android, iOS, and desktop
  • Full offline support via Service Worker — works without a network connection after first load
  • Auto-updates: on every page load while online, the app checks version.json on the server and busts the cache if a new version is available — no manual refresh needed

Typography

  • Rendered in Tiro Devanāgarī Sanskrit, designed for classical Sanskrit texts
  • Collapsible header for distraction-free reading on small screens

Pushing an Update

To force all users to fetch fresh assets after a deployment:

  1. Edit version.json and increment the version string:
    { "cache_version": "rigveda-v5" }
  2. Commit and push. The next time a user opens the app while online, the old cache is deleted and all assets are re-fetched automatically.

Data

The text is stored in rigveda.json — a flat key-value structure keyed by Rik number (MM.SSS.RR), with each entry containing:

  • text / samh_dev_acc — Samhitā text in Devanāgarī with Vedic accent Unicode marks
  • pada_dev_acc / pada_patha — Pada Pāṭha
  • rik_num — Maṇḍala.Sūkta.Mantra reference
  • ashtaka_ref — Aṣṭaka.Adhyāya.Varga.Ṛcā reference

The accent marks use standard Unicode: U+0951 (Udātta), U+0952 (Anudātta), and the Vedic Extensions block U+1CD0–U+1CFA.

Local Development

No build step. Just serve the files from a local HTTP server:

# Python
python -m http.server 8000

# Node (npx)
npx serve .

Then open http://localhost:8000. The Service Worker will register but cache-version checks won’t behave identically to production — use DevTools → Application → Service Workers → “Update on reload” during development.
