- Proxy notification image_url server-side (GET /api/v1/notifications/:id/image) instead of loading it directly in the browser, so LAN-only image sources (e.g. Frigate snapshots) still load for clients off that network - Tighten CSP img-src to 'self' now that images are same-origin - Update threat model / architecture docs to match the new image-fetch design - Expand README: Home Assistant quick-start, Pocket ID/OIDC walkthrough, Pangolin note, backup automation, new troubleshooting entries - Fix docker-compose.yml: document that --env-file .env must be passed explicitly (Compose's implicit .env lookup was unreliable with -f from a different directory) - Fix image-proxy tests to build a real session cookie (AUTH_MODE=oidc applies inside the test container too, so requireAuth needs one)

Notizarr — Phase 1 Design Package
This is the Phase 1 deliverable: architecture, threat model, data model, API design, PWA/Web Push design, Docker/Unraid design, folder structure, and the phased implementation plan. No application code is written in this phase. Per the project's own process rules, implementation (Phase 2+) does not start until this package is reviewed and the open decisions below are confirmed.
Documents
- 01-architecture.md — components, containers, data flow
- 02-threat-model.md — trust boundaries, STRIDE notes, mitigations
- 03-database-model.md — full Postgres schema
- 04-api-design.md — public app API + LAN ingestion API
- 05-pwa-web-push-design.md — manifest, service worker, push flow, iOS notes
- 06-docker-unraid-design.md — compose design, volumes, networking
- 07-folder-structure.md — repo layout vs. deployment layout
- 08-implementation-plan.md — Phase 2–10 task breakdown, mapped to MVP acceptance criteria
Open decisions that need your sign-off before Phase 2
These are the "major implementation decisions" the process asks to pause on:
| # | Decision | Recommendation | Why |
|---|---|---|---|
| 1 | Backend language/framework | Node.js 22 + TypeScript, Fastify | One language across front+back end for a solo-maintained homelab app; web-push and openid-client are the most mature libraries for the two hardest requirements (Web Push, OIDC); Fastify has first-class schema validation and low overhead. |
| 2 | ORM / migrations | Drizzle ORM + drizzle-kit | Typesafe, SQL-first, no native binary/engine (unlike Prisma) — simpler in a small Alpine container, plain-SQL migration files you can read and back up. |
| 3 | Realtime "instant in UI" delivery | Server-Sent Events (SSE), in-process pub/sub, no Redis | Single-instance app; SSE is one-way (all we need), works over plain HTTP through a reverse proxy, avoids the complexity of a WebSocket + no new infra. |
| 4 | VAPID key storage | Postgres system_settings table, generated on first boot if absent |
Already-durable volume; no separate key file to remember to back up — pg_dump covers it automatically. |
| 5 | Attachments / image handling | external_url is stored as a plain URL and rendered as <a href>, never fetched server-side. image_url is fetched server-side and proxied (GET /api/v1/notifications/:id/image) so a LAN-only image source still loads for a client off that LAN — narrowly scoped (no client-supplied URL, requires a scoped token to have set it, timeout + size cap), not a general-purpose fetch proxy. See 02-threat-model.md's SSRF section. |
A homelab client (phone on cellular) still needs to see camera snapshots from LAN-only sources like Frigate; a pure direct-browser-load design can't do that. Doesn't support arbitrary file uploads in v1 (can be added later as an explicit, scoped feature). |
| 6 | Webhook mapping | MVP ships a fixed simple mapping ({topic, title, message, url?} JSON body, or ntfy-style headers), not a configurable templating engine |
Spec says "goal is easy migration, not full protocol cloning"; a mapping UI is called out as a later enhancement. |
| 7 | Topic access control | Topics are visible to all authenticated users by default; an admin can mark a topic restricted and grant per-user access |
Matches "single/small household" simplicity principle while still satisfying "users can browse allowed topics." |
If any of these should go differently, say so and I'll adjust the design before Phase 2 starts. Otherwise, confirming this package moves us into Phase 2 (repo bootstrap + Docker Compose skeleton).
