will b7b5a63756 Add full Gospel pericopes to Advent/Christmas Sunday Matins readings
Nocturn 3 previously dropped the bare "Et réliqua" Gospel incipit and
kept only the patristic homily, so the Gospel citation and text never
appeared. Authors the full pericope before the homily for advent-1
through advent-4 and christmas-octave-sunday, sourced from the
reference engine's Missale Gospel files. Authoring Advent 4's Gospel
surfaces a genuine second Matins Gospel on the rare Dec-24-as-Advent-4
collision (2023/2028), so the affected test now expects both readings
instead of one.

vu

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.)
