The server still never sees a photo, so the model has to run in the page.
Real-ESRGAN x4v3 ships as a 4.9MB ONNX in public/models and is loaded
lazily on the first export that actually needs it; the wasm runtime is
copied next to CanvasKit at build time and stays lazily fetched, cached
for 30 days. Vite is told onnxruntime-web is external-wasm so no 28MB
asset lands in the bundle.
UNCHANGED keeps the old path and the tier cap; 2K/4K/custom upscale only
when the request is larger than the photo being edited, otherwise they
resize down. Guests keep UNCHANGED and 2K. Tiling is 256px with an 8px
overlap, so memory follows the target size rather than four times it.
A signed-in account is served exactly like a guest until it opens the
verification link: watermarked 2048px export, no saving, no PRO frames,
GPS stamp or HDF. SMTP is declared in .env; with SMTP_HOST unset the link
goes to the container log. Allowlisted admins count as verified.
- /admin User account rows gain BLOCK/UNBLOCK, REMOVE/RESTORE and DELETE.
Blocked = cannot sign in (sessions swept), removed = hidden from the strip
and cannot sign in, both reversible; DELETE drops the account with its
photos and recipes and unlinks the files. An allowlisted account is never
a target, so an admin cannot moderate or delete itself.
- Photo uploads move from a 3MB API cap / 4m nginx cap to 12MB / 16m, and
the browser shrinks an oversized still before sending it (2048px JPEG,
avatars 512px) so the declared type still matches the sniffed bytes.
- The studio SAVE leaves the top bar and sits under the CREATE RECIPES tab,
labelled SAVE RECIPES.
Backend
- photos table + upload storage under DATA_DIR/uploads (magic-byte sniffing,
no multipart dep, SVG rejected, wx exclusive writes)
- POST/GET /api/photos, GET /api/photos/:id/file with nosniff + sandboxed CSP
- admin routes (ADMIN_EMAILS allowlist): list, delete one, clear all
- identity-keyed rate limits (login 20/15m, signup 5/h, upload 60/h)
- cookie gains Secure when the request is https (via trustProxy)
- /api/auth/me now 200 {user:null} instead of 401 when signed out
Frontend
- landing strip section: signed-in users upload straight from the reel,
guests get a /app?auth=1 link
- /admin page: grid of uploads with delete + clear all
- nginx: nosniff / X-Frame-Options / Referrer-Policy, forward
X-Forwarded-Proto so the API can mark cookies Secure behind TLS
Tests: docker/backend test/security.mjs (45 checks)
`docker/` now holds the whole web build — frontend (Vite + React + CanvasKit),
backend (Fastify + SQLite) and the compose file — so the folder can be moved to
another machine and run without the React Native project:
cd docker && cp .env.example .env && docker compose up -d --build
Only `${WEB_PORT:-8090}` is published; nginx serves the SPA and proxies /api to
the `api` container over Docker's DNS. Photos never reach the server.
The shared render code is vendored into `docker/frontend/shared/` and aliased to
a CanvasKit shim, so the app's own frameUtils/toneShader/jpegDpi run unchanged.
Fix the all-black render on GPU surfaces: `MakeWebGLCanvasSurface` creates a
separate WebGL context per call, and a texture from one context cannot be
sampled by a surface on another — so any pass that drew a snapshot onto a second
surface (output sharpen, screen sharpen, polaroid/wallframe cards) came out
solid black, while the raster fallback was correct. Use one shared
GrDirectContext + MakeRenderTarget instead.
Verified in headless Chromium against the running stack: 12MP JPEG in, preview
mean=120.5 sd=60.5, export 2048x1536 mean=107.2 sd=62.1, JFIF density 300/300,
EXIF present, no console errors; health/signup/login/me/recipes all 2xx through
the nginx proxy.
