# Art Gallery — setup and operations

## Prerequisites

- **Node.js** 20+
- **PostgreSQL** reachable from the app host
- Network access to Wikipedia / Wikimedia (for biographies, seeding, and on-demand image fetch)

## Environment

Copy the example file and fill in credentials:

```bash
cp .env.example .env
```

| Variable | Description |
|----------|-------------|
| `DB_HOST` | PostgreSQL host |
| `DB_PORT` | Port (default `5432`) |
| `DB_USER` | Database user |
| `DB_PASSWORD` | Database password |
| `DB_NAME` | Database name (`gallery_dev` for dev; prod uses `gallery_prod`) |
| `PORT` | API listen port (`3451` for `dev:web`; prod container uses `5173`) |
| `HOST` | Bind address (default `0.0.0.0` — required for LAN access) |
| `PUBLIC_URL` | Public URL (dev: `https://devgallery.mysuperlab.netcraze.pro`; prod: `https://gallery.mysuperlab.netcraze.pro`) |
| `TRUST_PROXY` | Set to `true` when behind nginx/reverse proxy (honours `X-Forwarded-*`) |
| `IMAGE_DIR` | Root for cached images (default `./data/images`) |

Optional script tuning:

| Variable | Used by | Description |
|----------|---------|-------------|
| `MIN_PAINTINGS` | `expand-catalog` | Minimum paintings per artist (default `6`) |
| `FETCH_MAX_WAIT_SEC` | `fetch-images` | Max seconds per painting in batch runs (default `10`) |

`.env` is git-ignored; never commit passwords.

## Install

```bash
npm install
cd client && npm install && cd ..
```

## Database bootstrap

One-shot setup (migrate + seed):

```bash
npm run setup
```

Or step by step:

```bash
npm run migrate    # db/schema.sql + db/migrate-*.sql via server/migrate.js
npm run seed       # eras, movements, artists, flagship paintings (one per artist)
```

`npm run migrate` is safe to re-run on existing databases (uses `IF NOT EXISTS` / `ADD COLUMN IF NOT EXISTS`).

If migration fails with permission errors, grant schema rights to the app user first (see [DB_structure.md](DB_structure.md)).

### Recommended post-seed steps

After a fresh seed, run these to match a fully populated local install:

```bash
npm run sync-image-paths           # import paintings from data/images/paintings/ (clone with image files)
npm run fetch-artist-images        # link local portraits or download from Wikipedia
npm run fetch-artist-bios          # bio_short / bio_full from Wikipedia
npm run expand-catalog             # famous works for artists below MIN_PAINTINGS
npm run update-influences          # painting influence graph for detail view + hall exits
npm run migrate:checkup-flags      # optional: review/fixed flags for Checkup page (paintings)
npm run migrate:artist-checkup-flags  # optional: same flags for artist portraits (bio debug)
npm run migrate:painting-annotations  # optional: art-history notes table
npm run update-painting-annotations   # optional: load curated notes (+ --wikipedia for Wikipedia intros)
npm run fetch-images -- --limit=50                # random sample; 10s max per painting (default)
npm run fetch-images -- --limit=50 --max-wait=120 # same batch size, longer lookup per work
cd client && npm run build && cd ..
```

**Order matters:** `sync-image-paths` should run when the repo already contains painting files under `data/images/paintings/` but the database only has one flagship work per artist (typical after `npm run setup` on a clone). `update-influences` is required for *Influenced By* / *Influenced* panels and golden lamps in the 3D hall — seed does not insert influence edges.

Image fetch can take hours if you run it for the entire catalog. The first line of each run reports **`Missing local files: N`**. Use **`npm run fetch-images -- --limit=N`** for random batches (10s per painting by default), **`--artist="…"`** for one artist in catalog order, or on-demand resolution when viewing a painting in the detail view.

## Run

| Command | Purpose |
|---------|---------|
| `npm run dev:web` | **Public dev stack** — Vite `:5173`, API `:3451` (Keenetic → devgallery…) |
| `npm run docker:publish` | Build + push prod image to Gitea |
| `npm run images:sync-to-prod` | Copy `data/images/` → TrueNAS via SMB `Gallery` share |
| `npm run images:sync-from-prod` | Copy prod images → dev repo |
| `npm run db:sync-from-prod` | Clone `gallery_prod` → `gallery_dev` |
| `npm run db:backup` / `db:restore:prod` | Dev backup / promote to prod |
| `npm run build` | Build production SPA into `client/dist` |
| `npm run start` | API + static SPA on `HOST`:`PORT` |
| `npm run start:prod` | Build client, then start server |
| `npm run server` | Alias for `start` |
| `npm run dev:server` | API with nodemon reload (local `:3520` / `:5173` workflow) |
| `npm run dev:client` | Vite dev server on :5173 |
| `npm run dev` | Alias for `start` |

See [environments.md](environments.md) for dev/prod URLs, database split, Docker deploy, and sync commands.

**Production frontend:** build the client, then start the server:

```bash
npm run build
        # or: cd client && npm run build && cd ..
npm run start
```

Open http://localhost:5173 (Vite) or http://localhost:3451 (API only).

## Production deployment

Production runs as **`gallery-web`** on TrueNAS at **https://gallery.mysuperlab.netcraze.pro** (Keenetic → `:5173`). Full guide: [environments.md](environments.md) and [infra/docker/DEPLOY-truenas.md](../infra/docker/DEPLOY-truenas.md).

| Access | URL |
|--------|-----|
| Production (Keenetic) | https://gallery.mysuperlab.netcraze.pro |
| Development (Keenetic) | https://devgallery.mysuperlab.netcraze.pro |
| LAN direct (prod container) | http://192.168.10.122:5173 |
| LAN direct (dev PC) | http://192.168.10.70:5173 |

Quick deploy checklist:

1. One-time DB split in **pgAdmin** on dev PC: [`db/split-dev-prod-pgadmin.sql`](../db/split-dev-prod-pgadmin.sql)
2. Dev `.env` → `DB_NAME=gallery_dev`, `PORT=3451`, `PUBLIC_URL=https://devgallery.mysuperlab.netcraze.pro`
3. `net use \\192.168.10.122\Gallery` → `npm run images:sync-to-prod`
4. `npm run docker:publish` → TrueNAS Custom App from `infra/docker/compose.truenas.yaml`
5. Keenetic: both domains → `:5173`, protocol to device **`http`**, correct IP per environment

### Legacy deployment (optional)

Node on the dev PC at `:3520` with nginx → Vite `:5173` is superseded by TrueNAS Docker prod and `npm run dev:web` for public dev. See [`deploy/nginx-gallery.conf`](../deploy/nginx-gallery.conf) and [`deploy/gallery.service`](../deploy/gallery.service) only if you need a local nginx/systemd setup.

## Troubleshooting

| Symptom | Likely cause | Fix |
|---------|--------------|-----|
| Empty timeline | DB not seeded | `npm run seed` |
| 502 / 504 on public URL | Keenetic rule wrong (IP, port, or `https` to device) | Dev → `192.168.10.70:5173`; prod → `192.168.10.122:5173`; protocol **`http`** — see [environments.md](environments.md) |
| 503 on public URL | Dev servers not running | `npm run dev:web` (or `dev:server` + `dev:client` for local HMR) |
| **`manifest unknown`** on TrueNAS deploy | Image not in Gitea | `npm run docker:publish` on dev PC first |
| 500 on all `/api/*` | Wrong `.env` or Postgres down | Check connection, logs |
| “Biographical information not yet available” | Bios not fetched | `npm run fetch-artist-bios` |
| Placeholder portraits on timeline | `portrait_path` not set | `npm run fetch-artist-images` |
| Artist hall has only 1–2 paintings | DB not expanded / disk not imported | `npm run sync-image-paths` then `npm run expand-catalog`; extend `famous-paintings-data.js` |
| Movement flow shows “Loading art history…” repeatedly | Stale client refetching on every pan/zoom | Pull latest client; timeline loads catalog once — hard-refresh |
| Movement flow slow on first load | Large artist payload | Client uses `GET /api/artists?timeline=1` (no full bios); rebuild client |
| Movement flow zoom sluggish / dead over portraits | Stale client build | Rebuild client — wheel uses capture listener + interaction-mode rendering; hard-refresh |
| Timeline year labels overlap when zoomed out | Stale client | Rebuild client — `chooseTimelineTickInterval()` adapts step to span and bar width |
| Black frames / canvas covers in 3D gallery | No local image for painting | `npm run fetch-images -- --limit=50` or `--artist="…"`; then `POST …/preload-images` |
| Many `⏱ timeout` lines in fetch batch | Default 10s cap too short for hard works | `--max-wait=120` or raise `FETCH_MAX_WAIT_SEC` |
| White/grey flicker on frames | Texture loading or z-fighting with wall | Rebuild client (`cd client && npm run build`); ensure latest `VirtualGallery.tsx` |
| Wrong painting in 3D gallery frame | Stale or mismatched thumbnail file | `npm run regenerate-thumbnails`; gallery prefers full `image_path` |
| Wrong painting image (fetch) | Bad museum / search match on first download | Add entry to `DIRECT_IMAGE_OVERRIDES` in `scripts/image-fetcher.js`, re-fetch file |
| Empty exit navigation lists | No influence edges for artist | `npm run update-influences`; check `painting_influence_sources` |
| Empty *Influenced By* / *Influenced* on painting detail | No edges for that work | `npm run migrate:influence-sources` then `npm run update-influences`; extend `art-influences-data.js` or run `--discover` |
| Same work listed twice under *Influenced* | Stale server merging legacy + sources tables | Restart server; API reads `painting_influence_sources` only — run `npm run audit-influence-duplicates` to verify DB |
| No golden lamps above frames in 3D hall | Stale API process or no influence edges | Restart server after API changes; run `npm run update-influences` |
| Default Vite page instead of gallery | `client/dist` missing or stale | `cd client && npm run build` |
| Permission denied creating tables | `gallery` user lacks CREATE | Run admin grants, then migrate |
| Wikipedia API rate limit during fetch | Too many requests in a row | Wait and re-run; scripts retry with backoff |
| Checkup **Reviewed** toggle returns 404 | Stale server process missing new routes | Restart `npm run dev` after pulling API changes |
| Debug **More** / **Clear** / **Upload** / **Remove entry** returns 404 | Stale server process | Restart `npm run start` or `npm run dev:server`; routes in `server/index.js` + `server/image-service.js` |
| Debug **Remove entry** — button stuck or missing on next painting | Stale client build | `cd client && npm run build`; hard-refresh — detail view remounts per painting id |
| Debug **Upload** returns 413 Payload Too Large | Base64 JSON exceeds body limit | Server allows 20 MB JSON / 15 MB decoded image; compress file or resize before upload |
| No art-history notes on painting detail | Annotations not migrated or loaded | `npm run migrate:painting-annotations` then `npm run update-painting-annotations` |
| **Fix it** fails with `read ECONNRESET` | Remote host dropped connection | Restart server; client sends `searchUrl` / `source`; retry or use Commons URL in overrides |
| Fixed image not shown in 3D gallery | Stale gallery session or cached texture | Rebuild client; fix updates session + `?v=` revision — use **Back to Gallery** (not browser back) |
| Frame still black after **Checked** | Gallery session not synced | Re-enter hall or toggle debug **Checked** from detail with gallery open behind overlay |
| Duplicate works in gallery / timeline | Double import or variant Wikipedia titles | `npm run find-duplicates`; merge or delete spare rows manually |
| **Failed to load movement gallery** / `Cannot GET /api/movements/:id/gallery` | Stale server process missing route | Restart `npm run dev` or `npm run dev:server` after pulling API changes |
| Movement gallery shows generic cream walls | Stale client build | `cd client && npm run build`; hard-refresh browser |
| Windows overlap paintings in movement wing | Stale client | Rebuild client — windows are placed only on side walls in gaps between frames |
| Influence thumbnails cropped on painting detail | Stale client build | `npm run build` — panels use `object-fit: contain` for full image |
