Four asks, one screen: a folder can be given the tiles it is short of, by hand or on the way in; the rescan row says RESCAN...; and the wall of thumbnails scores a frame without the trip to the stage. - Library.tsx + i18n: "RESCAN FROM THE TOP" is "RESCAN..." in both languages. The reading is unchanged — a row's roll is still read from the top, its subfolders included. - engine/library.ts + Library.tsx: the tile of one frame is one function now (`makeThumb`: the store, the backup behind it, then the file's own preview for a RAW or a HEIC and a decode for anything else). The wall's lazy path calls it instead of keeping its own copy of the same branches. - engine/library.ts: `missingThumbs` asks which of a folder's rows no tile was ever drawn for, in one transaction, and `makeThumbs` makes those — a few frames at a time, and giving up when the caller has moved on. - Library.tsx: the folder menu carries MAKE THUMBS, which reads the row's folder and what lies under it; and opening a folder asks for its own frames' tiles by itself, silently, in the background — the branch too when the screen is drawing the branch. A frame that lands after the ask is asked for again, which is why the frame count is a dependency of the effect. - Library.tsx: a wall card carries the same five stars the stage does, under the picture, and rates the frame on the click. The click stops at the star, so scoring a frame is not picking it. Verified in Chrome at 1440x900 against OPFS standing in for the disk, three frames with one of them in a subfolder: opening the folder leaves two tiles (the node's own frames) and MAKE THUMBS takes the roll to three, the frame in the subfolder included; clearing the store and reloading brings the two back on the open; the menu reads RESCAN... and MAKE THUMBS; and the wall's fourth star lights four, writes star 4 to the catalogue row, and takes it back on the second click. The same checks pass on the built bundle at :8090.
RecipesCam web — self-contained stack
A Docker-hosted web build of RecipesCam. Everything it needs is in this folder: move it to another machine, run two commands, and the app is up. It does not need the React Native project around it.
cp .env.example .env
docker compose up -d --build
# → http://localhost:8090
What runs where
| Service | Image | Role |
|---|---|---|
frontend |
nginx:1.27-alpine (built by frontend/Dockerfile) |
Static SPA + /api/ reverse proxy |
api |
node:22-slim (built by backend/Dockerfile) |
Accounts + saved recipes, SQLite on ./data |
frontend resolves api through Docker's embedded DNS and proxies /api/* to
it — that is why the API container is named api and why it is not published on
the host. Only ${WEB_PORT:-8090} is exposed.
Photos never leave the browser. The CanvasKit render pipeline (grade, frame, watermarks, JPEG encode) runs in the visitor's tab; the API only stores recipes as JSON.
Layout
docker-compose.yml the stack
.env.example WEB_PORT
data/ SQLite (created on first run, gitignored)
backend/ Fastify + better-sqlite3 API, own Dockerfile
frontend/ Vite + React + CanvasKit SPA, own Dockerfile + nginx.conf
shared/ vendored copies of the app's types + utils (see below)
src/engine/ skiaShim.ts (CanvasKit) + exportEngine.ts (render pipeline)
+ session.ts (localStorage/IndexedDB studio persistence)
Vendored files
frontend/shared/{types/index.ts,utils/*.ts} are byte-identical copies of
src/types/index.ts and ten src/utils/*.ts files from the React Native
project (@shopify/react-native-skia is aliased to src/engine/skiaShim.ts in
vite.config.ts + tsconfig.json, so those files compile unchanged):
cinemaShader colorUtils defaultRecipes exifWrite frameUtils jpegDpi
paramDefs recipeShare skiaImage toneShader.
The landing page needs no CDN: frontend/public/assets/fonts/*.woff2 are the
seven self-hosted faces behind the three font groups the Themes menu offers
(Plus Jakarta Sans / Inter / JetBrains Mono, Fraunces / Be Vietnam Pro /
Courier Prime, Be Vietnam Pro / Space Mono — all SIL OFL, pulled from Google
Fonts, vietnamese + latin + latin-ext subsets), and
frontend/public/assets/samples/s*.jpg are the six placeholder negatives the
film strip, preset tester and QR card show (swap them for real graded stills
whenever we have them). Its one foreign request is the QR image from
api.qrserver.com, which degrades to an empty slot offline.
When the app changes one of them, copy it back in — the renderer is only "parity" for as long as these stay in sync:
cd <repo>/docker/frontend/shared/utils
cp <repo>/src/utils/<name>.ts .
Operations
docker compose logs -f api # API log
docker compose restart api # after backend/src changes (rebuild: --build)
docker compose down # stop; ./data survives
Backup is the ./data folder — that is the whole database.
Checks
curl -s http://localhost:8090/api/health # {"ok":true}
curl -sI http://localhost:8090/ # 200, index.html
Then open the UI, drop a photo in, and confirm the preview shows the picture and
EXPORT downloads a JPEG that opens. The preview going solid black while the
export still reports a plausible size is the one failure mode worth knowing: it
means the CanvasKit GPU surfaces lost their shared GrDirectContext (see
frontend/src/engine/skiaShim.ts), and with no GPU the raster fallback renders
the same pipeline correctly, just slower.
