Nov 1's own content had several real gaps and one transcription bug,
found live-verifying against Divinum Officium (Monastic Tridentinum
1617, 2026-11-01, clean year):
- Matins Nocturn 3 had no Gospel (Matt 5:1-12, the Beatitudes) or St.
Augustine's homily on it -- a 2026-09-05 pass had wrongly assumed a
duplex-1-classis feast like this one shouldn't carry its own
Gospel/homily pairing. Authored with the full canonical text (chased
down via the Mass propers' own Evangelium, since Matins' own lesson
gives only a bare "Et réliqua" incipit) rather than just the incipit.
- Vespers had no Magnificat antiphon at all ("O quam gloriósum est
regnum...").
- Vespers had no proper psalmody override, so it fell back to the plain
4-psalm Sunday default; the real office uses 5 psalms (109/110/111/
112/115), each with its own proper antiphon.
- Both the Lauds and Vespers hymn files had the right English translation
paired with the WRONG Latin recension (the 1631 Urban VIII revision,
"Jesu Salvátor sæculi"/"Christe Redémptor ómnium") -- the live Monastic
engine actually renders the older pre-Urban VIII text ("Salútis ætérnæ
dator" for Lauds, "Placáre, Christe, sérvulis" for Vespers/Matins,
confirmed identical between those two hours). Corrected both, and
authored Matins' own hymn file (previously missing entirely, silently
falling back to the plain ferial hymn).
- St. Raphael the Archangel's own Nocturn 3 Gospel (John 5:1-4) was
previously left as homily-only because Matins' own lesson gives only a
bare incipit -- same fix as All Saints, full text recovered from the
Mass propers instead.

A static, offline-first PWA for praying the Divine Office — Matins, Lauds, Prime, Terce, Sext, None, Vespers, and Compline — in bilingual Latin/English, for any given date.
This isn't a reconstruction of any single historical breviary. It's a personal design that
draws on several historical sources without reproducing any one of them exactly: hour
structure chiefly from the Monastic Tridentinum (1617), precedence/rubrics from Divino
Afflatu, and a calendar merged from both the Tridentine 1906 and Divino Afflatu calendars,
with more generous handling of commemorations and octaves than any one historical rite used.
See CLAUDE.md (gitignored, not shipped in this repo) or the project's own notes for the full
rationale if you're extending it.
There's no backend and no database — everything is a pre-built static bundle, and the app is designed to keep working fully offline once it's been loaded once.
Development
Requires Node.js (developed against Node 20+).
npm install
npm run dev # start the Vite dev server
npm run build # type-check (tsc --noEmit) and produce a production build in dist/
npm run preview # serve the production build locally
npm test # run the test suite (vitest)
Run a single test file or a subset by name:
npx vitest run tests/hours/vespers.test.ts
npx vitest run -t "some test name"
Running in production
The app is entirely static once built, so "running it" just means serving dist/ — any static
file host works, as long as it falls back to index.html for unknown paths (the app does its
own client-side routing for URLs like /2026-08-09/prime).
Docker
A Dockerfile builds the static bundle with Node and serves it with Caddy:
docker build -t vu .
docker run -p 8080:80 vu
Or with Docker Compose (docker-compose.yml is included):
docker compose up -d --build
This serves the app on http://localhost:8080. Put a reverse proxy/TLS terminator in front of
it for a real deployment; the container itself just listens on port 80 internally and has no
configuration, secrets, or external dependencies.
Without Docker
Any static file server works — build the app, then serve dist/ with SPA-style fallback
routing. For example, with Caddy directly:
npm run build
caddy file-server --root dist --listen :8080
(For a real deployment you'll want a fallback rule so unknown paths resolve to index.html —
see the Caddyfile in this repo for the pattern.)
