# Goal: Directus image preview pre-generation
Status: SCAFFOLDED — opened 2026-10-25. Standalone extension project (not part of the
landshaft.life app repo).
Location: `/home/rawman/Projects/DirectusExtensions/directus-extension-generate-image-previews`
Target server: `land-nest`, Directus **11.17.4** (self-hosted, PM2 cluster, local disk storage).
Project type: Directus **bundle** extension (app module + api hook + api endpoint).
## Summary
Pre-generate Directus image transform ("preview") cache files so the admin UI never pays the
first-request sharp cost. One warmer, several triggers:
- **upload hook** — after an image upload, warm its previews.
- **new-preset trigger** — when a storage asset preset is added/changed, warm it for existing images.
- **backfill job** — a resumable, scheduled sweep over the existing `directus_files` library, inside a
configurable maintenance window.
- **manual / diagnostics** — generate (or dry-run) previews for a single file on demand, to debug.
Plus an **admin module** ("Image Previews") with a **progress bar**, **disk usage**, a **config form**
(persisted, no rebuild), and a **diagnostics panel**.
## Verified mechanism (source-checked against tag v11.17.4)
The on-disk transform cache file is:
```
<basename(filename_disk)>__<object-hash(resolved transforms)>.<ext>
```
written **beside the original** in the storage root (`STORAGE_LOCAL_ROOT=./uploads`).
- `hash` = `object-hash@3` defaults: sha1/hex, `unorderedArrays:false` (**array order matters**),
`unorderedObjects:true`. Hashed over the **RESOLVED** transform array from `resolvePreset`.
- `resolvePreset` order is fixed: `(1) copy transformationParams.transforms[]`, `(2) push toFormat`
(if `format`/`quality`), `(3) push resize` (+`extract` on focal cover).
- `maybeExtractFormat` picks the last `toFormat` arg as the file extension.
- `AssetsService.getAsset` checks `exists(assetFilename)` first (cache hit → no sharp); on miss runs
sharp and **awaits** `storage.write(...)` before returning. Not draining the returned stream only
leaks an FD (never truncates).
- Called as sudo (`new AssetsService({ schema })`) it needs **no** HTTP request context.
## Why the naive / community approach FAILS (must not repeat)
1. **`{ key }` alone is a no-op.** `resolvePreset` never reads `key`. Pass the **full preset object**.
2. **`format:'auto'` mismatch.** Every `system-*` preset is `format:'auto'`. `getFormat` with no
`acceptFormat` → JPEG→`jpg`/PNG→`png`; a browser `Accept: image/avif` → `avif`. Different
`toFormat` arg → different hash → **guaranteed miss**.
3. Disproved myths: the write is awaited; the admin does NOT use `width`/`height`.
4. Raw params resolve to `[toFormat, resize]`; a preset resolves to `[resize, toFormat]` → different hash.
## Chosen strategy — IN-PROCESS generation (no token, no HTTP, no rate limiter)
Because this is an internal extension, generate by calling Directus's own service in-process:
```ts
const assets = new services.AssetsService({ schema }); // sudo
const { stream } = await assets.getAsset(fileId, {
transformationParams: presetObject, // FULL object, not { key }
acceptFormat: 'avif', // or 'webp'
});
(stream as Readable).destroy?.();
```
`acceptFormat` reproduces exactly what a browser's `Accept` header does, so the cache filename is
byte-identical to the admin/browser read — **without any HTTP request, token, proxy, or rate limiter**.
Generate **two variants** for `format:'auto'` presets (`avif`, `webp`); fixed-`format` presets yield
one; resize-only presets (no `format`/`quality`) yield none.
HTTP-replay (`GET /assets/{id}?key=…` with a browser `Accept` + auth) is the documented **fallback**
only — it needs a token and rate-limiter pacing, which is why it is not the default.
## Preset registry (system + settings, dynamic)
The controller builds its preset list inline as:
```
res.locals['shortcuts'] = [...SYSTEM_ASSET_ALLOW_LIST, ...(directus_settings.storage_asset_presets ?? [])]
```
and resolves `?key=` with `.find(t => t.key === key)` → **first match wins** (a system key shadows a
custom preset of the same key). There is **no** reusable helper and `GET /settings` exposes **only**
custom presets.
Our registry (`src/lib/presets.ts`) mirrors this exact list:
- **System presets**: 6 objects in `SYSTEM_ASSET_ALLOW_LIST` (`system-small|medium|large` ×
`cover|contain`), each `format:'auto'`, resize inside `transforms[]`; sourced at runtime from
`@directus/api` **if** importable, else the version-pinned copy `src/lib/system-presets.ts` (v11.17.4).
- **Custom presets**: read `directus_settings.storage_asset_presets` each run; pass the verbatim object.
- **Dynamic**: newly created presets are picked up per run; the new-preset trigger warms them for
existing images.
## Admin UI (module "Image Previews")
- **Progress**: bar + `done / total / remaining`, throughput, ETA, last-run, next-window; live during a run.
- **Storage breakdown**: bytes + file counts separately for **preview assets** (`__<hash>`), **original
assets**, and the total — raw and human-readable. Computed by listing the storage root and `stat()`-ing
each file (listing yields paths only, no sizes); the state dir is excluded.
- **Config form** (persisted, no rebuild; defaults `enabled:true`, window `01:00–04:00`): `enabled`,
maintenance window, concurrency, preset selection, formats, `onUpload`, `debug`; each field carries a
plain-language explanation. **Run now** ignores the window; **Cancel** is shown only while a run is active.
- **Diagnostics panel**: recent operations, per-file generate/dry-run, resolve-plan viewer.
## Diagnostics & manual generation (observability)
- `POST /image-previews/generate` `{ fileId, keys?, formats?, dryRun? }` → generate (or dry-run) for ONE
file; returns per `(key,format)` `{ ok, failed, cached, filename, bytes, ms, error }`. Primary dev tool.
- `GET /image-previews/resolve-plan?fileId=&key=` → resolved transforms + **predicted cache filename** +
whether it already exists, WITHOUT generating. The hash-match debugging tool.
- `GET /image-previews/ops?limit=` → recent-operations ring buffer (timestamp, fileId, key, format, ok, ms, error).
- `debug` setting enables verbose structured logs; logs carry ids/metadata only, never file contents.
- Everything except `/generate` is read-only.
## Safe deployment & staging (must not crash prod)
- **Fail-open, inert by default**: every entrypoint is tiny, bodies wrapped in try/catch, hooks never
throw into Directus core, and ALL behavior is gated by `enabled` (default `false`). A loaded-but-disabled
extension does nothing.
- **Local dev**: `directus-extension link` (or the dev compose stack) loads `src/` live for iteration.
- **Staging stack**: a second compose project (`dev/compose.dev.yml`) running the SAME Directus 11.17.4
image with its own pg+redis, a **restored anonymized dump**, and a **copy of uploads**, on a separate
port — realistic data, zero prod risk.
- **Rollout discipline**: build → verify on staging → back up the previous `dist/` → copy in → healthcheck
→ enable via config → rollback = restore previous `dist/` + disable.
- `EXTENSIONS_AUTO_RELOAD` in prod reloads on file change; deploy with it controlled and accept the brief
reload, or restart deliberately.
## Remote feedback & autonomous operation (security)
- Feedback channel = the extension's own **machine-readable endpoints** (`/status`, `/ops`,
`/disk-usage`, `/resolve-plan`). Automation reads those, not CMS content.
- **Least privilege**:
- A Directus **admin token = full CMS control**. Do NOT give it to an autonomous loop. Use a scoped
token reaching only `/image-previews/*` (+ `directus_files` metadata read).
- A **Docker socket = root-equivalent**. Never expose the prod socket to automation; keep the loop on staging.
- Deployment access = a dedicated **non-sudo** SSH user with a restricted key (`restrict`, `from=`,
`command=`), or run opencode on the staging host via `handoff`.
- **Network**: staging reachable only over a private network / VPN / tunnel — never public.
- **Prompt-injection**: treat logs, filenames, and image metadata as untrusted input; keep tooling scoped.
- **Promotion to prod is a human action**: the loop proposes, a human merges/deploys.
- Guard long autonomous runs with a cost/time budget.

dev/

```
## Non-goals
- No Directus upgrade (server stays on 11.17.4; license constraint).
- No change to admin preset configuration or to how the admin builds URLs.
- Never hand-write `__<hash>.<ext>` filenames.
- No CDN/nginx caching work (separate ops concern). No image `quality` policy change.
- Automation never gets prod Docker socket or a full prod admin token.
## Constraints / risks
- `ASSETS_TRANSFORM_MAX_CONCURRENT=45` per worker; over it errors. Catch per file/preset and continue
(never fail the upload).
- `ASSETS_TRANSFORM_IMAGE_MAX_DIMENSION` default 6000 is a **pixel dimension** guard in Directus, not a
file-size limit. The extension imposes no limit of its own; raise the Directus env var to process larger
images (watch memory). Upload-size limits (`FILES_MAX_UPLOAD_SIZE`, `MAX_PAYLOAD_SIZE`) are unrelated.
- Local storage write is **non-atomic** → warm only AFTER an upload is committed; serialize so the
upload hook and the backfill never generate the same file concurrently.
- PM2 cluster (8 workers): the upload hook fires on the handling worker; the backfill runs in the worker
that served the run request. Shared state MUST be file/DB-backed (never in-memory).
- In-process backfill competes with live API serving → the maintenance window + concurrency cap govern
that. (HTTP rate limiter is irrelevant in-process.)
- Observed server bottleneck (2026-10-23): `storage:local:responseTime 1206ms`, `pg:responseTime`
150–738ms; no 503s, no sharp errors.
## Verification policy
- `npm run typecheck` → 0 errors; `npm test` (node:test via tsx) green.
- **The hash-match gate (F09)**: for a real file, the on-disk filename produced by a browser/admin
request for `?key=system-medium-cover` is byte-identical to the warmer's output for the same key+format
(+ the resolved extension matches, e.g. `.avif`).
- Cold-vs-warm timing; preview-file count + total bytes before/after a run.
- All feature testing happens on the **staging** stack; prod deploy only at goal completion, via the
documented backup/rollback procedure.
## Expected files
- `package.json`, `tsconfig.json`, `.gitignore`
- `src/hook/`, `src/endpoint/`, `src/module/`, `src/lib/`, plus `src/**/*.test.ts`
- `dev/compose.dev.yml`, `dev/seed/`
- `.opencode/goal.md`, `.opencode/feature_list.json`, `.opencode/progress.txt`
- `README.md`, `AGENTS.md`
## Resolved decisions (2026-10-25)
1. State/config: JSON files under `<STORAGE_LOCAL_ROOT>/.image-previews` (default
`/directus/uploads/.image-previews`), override with `IMAGE_PREVIEWS_STATE_DIR`. The former
`/directus/extensions/.image-previews` default was rejected — root-owned volume → `EACCES`.
2. System presets: version-pinned copy (`src/lib/system-presets.ts`, verbatim v11.17.4); no
`@directus/api` import needed for presets.
3. New-preset trigger: manual `POST /run` (idempotent) + the module's Run button; no
`settings.update` auto-trigger.
4. Backfill scheduling: external cron → `POST /image-previews/run`.
5. Dev/staging: isolated local compose stack (`dev/compose.dev.yml`). A land-nest staging project is
still to be created for realistic-data runs.
6. Autonomous-loop grants: still to be defined (scoped token / restricted SSH, staging only).
## Implementation status (2026-10-25)
Implemented and verified against an isolated Directus 11.17.4: settings/state, presets + warmer,
upload hook, diagnostics, backfill, endpoints. `npm test` 32/32, typecheck clean, build emits both
bundles. **Hash-match gate passed** (a real browser-style asset request produced exactly the
predicted filename). Features F03–F06, F08, F09 pass.
Outstanding: admin-module browser verification (F07), staging deploy/rollback + prod rollout (F02/F10),
and the F01 publish-to-staging step.
## Reference: source anchors (v11.17.4)
- `api/src/services/assets.ts` — `getAsset`, `getAssetSuffix`, filename build, awaited `write`.
- `api/src/utils/transformations.ts` — `resolvePreset`, `getFormat`.
- `api/src/controllers/assets.ts` — inline `shortcuts = [...SYSTEM_ASSET_ALLOW_LIST, ...settings]`,
`acceptFormat` selection from `req.headers.accept`.
- `api/src/constants.ts` — `SYSTEM_ASSET_ALLOW_LIST` (6 presets, `format:'auto'`);
`ASSETS_TRANSFORM_IMAGE_MAX_DIMENSION` default 6000.
- `app/src/utils/get-asset-url.ts`, `app/src/layouts/cards/components/card.vue`,
`app/src/interfaces/file-image/file-image.vue`, `app/src/displays/image/image.vue` — admin URLs:
Files grid `?key=system-medium-cover&v=<modified_on>`; image field `system-large-cover|contain`;
image display `system-small-cover`.
- `packages/storage-driver-local/src/index.ts` — non-atomic `write`; `list()` returns paths only.

# progress.txt — directus-extension-generate-image-previews
Append-only log of decisions, evidence, and learnings. Newest at the bottom.
## 2026-10-25 — project scaffolded
- Opened this standalone extension project to pre-generate Directus image previews.
- Source-verified the strategy against Directus **v11.17.4** (see `.opencode/goal.md`).
- Root causes why existing/community extensions do not work:
1. `resolvePreset` never reads `key` → `{transformationParams:{key}}` yields `transforms=[]` → no-op.
2. `system-*` presets are `format:'auto'` → `jpg`/`png` server-side vs `avif` in-browser → different hash.
3. "undrained stream truncates file" — false (write is awaited).
4. admin uses `?key=system-*`, not raw width/height.
- Admin URLs (v11.17.4 app source): files grid `?key=system-medium-cover&v=<modified_on>`;
image field `system-large-cover|contain`; image display `system-small-cover`.
- Server bottleneck evidence (2026-10-23 log triage): `storage:local:responseTime 1206ms`,
`pg:responseTime` 150–738ms; no 503s, no sharp errors.
## 2026-10-25 — scope expanded after user direction (v2)
- **No token needed.** Dropped HTTP-replay as primary. Strategy: **in-process**
`AssetsService.getAsset(id, { transformationParams: <full preset object>, acceptFormat: 'avif'|'webp' })`.
No HTTP → no token, no proxy, no rate limiter. (HTTP-replay kept as documented fallback.)
- **Bundle extension**: api `hook` + api `endpoint` + app `module`.
- **Presets: all, dynamically** — system `SYSTEM_ASSET_ALLOW_LIST` (6) + `directus_settings.storage_asset_presets`,
controller order `[...SYSTEM, ...custom]`, first-match-wins; new presets picked up per run.
- **Admin module**: progress bar, disk usage (`list`+`stat`), config form, diagnostics panel.
- **Config**: maintenance window + concurrency (throttle knob; in-process bypasses HTTP rate limiter),
persisted in JSON.
- Confirmed `acceptFormat:'avif'` in a direct call equals browser `Accept: image/avif`.
## 2026-10-25 — diagnostics + safety + autonomy (v3)
- **Diagnostics / manual generation** (F06): `POST /generate` (one file, dry-run supported),
`GET /resolve-plan` (resolved transforms + predicted filename, no write), `GET /ops` (ring buffer).
- **Safe testing** (F02): staging compose stack + deploy/rollback scripts; fail-open, `enabled` default false.
- **Autonomous remote feedback**: staging-only, least privilege (scoped token, no prod Docker socket,
restricted SSH, private network, human-only prod promotion).
## 2026-10-25 — implementation + local verification (autonomous session)
Built the full extension locally and smoke-tested against an **isolated** Directus 11.17.4 stack
(`dev/compose.dev.yml`, port 8057, own pg + volumes). No contact with the prod instance.
### Implemented
- `src/lib/`: settings (env + JSON), state (`state.jsonl`, run state, lock, cancel flag),
presets (pinned system copy + custom merge, controller parity), warmer (in-process `getAsset` with
`acceptFormat` variants, concurrency, per-task error isolation, stream release), window, storage
(dynamic `getStorage` + local-FS fallback), diagnostics (resolve-plan prediction + ops ring buffer),
backfill (paginated, resumable, window-aware, idempotent).
- `src/endpoint/index.ts`: `/status`, `/config` (GET/PUT), `/presets`, `/run`, `/run/cancel`,
`/disk-usage`, `/generate`, `/resolve-plan`, `/ops`; admin-only guard.
- `src/hook/index.ts`: `files.upload` → fire-and-forget warm.
- `src/module/`: admin module (progress bar, disk usage, config form, diagnostics panel, ops table).
- `dev/`: compose stack, `sync-extension.sh`, seed images.
### Bugs found & fixed during smoke test
1. **Directus coerces env values** (`"true"` → boolean `true`, `"1"` → number). My string-only parsers
threw `e.toLowerCase is not a function`, which silently broke the upload hook. Fixed `settings.ts`
to accept `unknown` and stringify. Regression test added.
2. **State dir EACCES.** `/directus/extensions/.image-previews` (named volume on a non-existent path)
is root-owned; the API runs as `node`. This broke config writes and the backfill lock. Fixed: default
state dir is now `<STORAGE_LOCAL_ROOT>/.image-previews` (i.e. `/directus/uploads/.image-previews`),
which is writable; `IMAGE_PREVIEWS_STATE_DIR` still overrides.
3. **Bind-mount reload gotcha.** `rm -rf` of the bind-mounted extension dir breaks the Docker mount
(Directus removes the extension and never re-adds it). `sync-extension.sh` now updates in place;
restart the dev container after a sync.
### Verified evidence (local stack)
- `npm run typecheck` → 0 errors. `npm test` → **32/32 pass**. `npm run build` → `dist/app.js` + `dist/api.js`.
- Directus logs: `Loaded extensions: directus-extension-generate-image-previews` (no errors).
- `/status` → `{enabled:true, inWindow:true, locked:false}`; `/presets` → 6 system presets.
- Upload a JPEG → hook warmed **12 files** (6 presets × avif/webp) in `/directus/uploads`.
- **HASH-MATCH GATE PASSED:** after deleting the cached files, a real
`GET /assets/<id>?key=system-medium-cover` with `Accept: image/avif` produced exactly
`<id>__f15aa4b815722867859d2a3fa46ab50834dfc8dc.avif` — byte-identical to `resolve-plan`'s prediction.
- `/generate` dry-run reports `exists:true/false` correctly; `/ops` shows per-task timing.
- Backfill: `total=36` (3 images × 6 presets × 2 formats), `generated=36`, state `state.jsonl` = 36 lines.
Second run: `generated=0, hits=36`, state unchanged, file count unchanged → **idempotent/resumable**.
- Window gating: `/run` outside `03:00–05:00` → `409 outside-window` with `nextWindow`.
- `/disk-usage` → `157633 bytes / 36 files (source: storage)`.
- Cold vs warm (`system-medium-cover`): 114 ms → 16–30 ms. (`system-large-cover`): 304 ms → 36 ms.
### Decisions recorded
- System presets: version-pinned copy in `src/lib/system-presets.ts` (verbatim from `api/src/constants.ts`
v11.17.4). No `@directus/api` import needed for presets.
- Storage/disk usage: `@directus/api/storage/index` loaded via dynamic import (hidden from the bundler),
with a local-FS fallback; shares the host `getStorage()` singleton.
- New-preset trigger: **manual** via `POST /run` (idempotent) + the module's Run button; no
`settings.update` auto-trigger (avoids heavy background runs on unrelated settings changes).
- Scheduling: external cron → `POST /image-previews/run` (default).
- State/config dir: `<STORAGE_LOCAL_ROOT>/.image-previews` (writable), override with `IMAGE_PREVIEWS_STATE_DIR`.
### Additional verification (same session)
- `GET /extensions` → bundle registered with entries `module`, `hook`, `endpoint`, all enabled.
- Inert test: with `enabled:false`, uploading an image produced **zero** new preview files (25 → 25).
- Added `dev/compose.staging.yml`, `dev/deploy-staging.sh`, `dev/rollback-staging.sh` (templates;
NOT executed against any remote host).
- Added `storage.test.ts`; total tests now **34/34**.
- Restarted the dev stack after the final build; `/status`, `/disk-usage`, and bundle entries all good.
### Still open
- Admin module UI not yet verified in a real browser (bundle + entries registered; rendering/polling untested).
- Cancel + concurrent-run 409 not exercised end-to-end (unit-tested only; local runs finish too fast).
- Staging deploy not executed (scripts/templates provided); prod rollout not done.
- F01/F02/F07/F10 remain `passes:false` (F01 publish step, F02 staging run, F07 browser, F10 rollout).
## 2026-10-25 — feedback round (UI, defaults, custom formats, docs)
- **Defaults changed**: `enabled` now `true`; maintenance window defaults to `01:00–04:00`.
- **Custom fixed-format presets verified**: `custom-png` (format `png`) generated `.png` and
`resolve-plan` predicted the exact filename (`exists:true`). `custom-auto` generated avif+webp.
An unsupported preset (`format: bmp`) failed with Directus's clear error
("Expected one of: heic, heif, avif, jpeg, … received bmp") and is surfaced in Recent operations / `/ops`.
- **Effective format fix**: ops/presets now report the preset's real output format (`png`) instead of
`null`; backfill resume keys use the effective format (fixed a re-warm mismatch).
- **Progress accounting fix**: already-cached tasks now count toward `done`/`hits`. Runs report
`128/128` (120 hits + 8 expected failures) instead of `8/128`. After removing the unsupported preset:
`120/120 hits, 0 failed, 0 generated`.
- **Storage reporting**: `/disk-usage` + panel now split **previews** vs **originals** vs **total**
(raw + human): e.g. previews 774.7 KB / 115 files, originals 24.9 MB / 9 files, total 25.6 MB / 124.
- **Human-readable fields** added to `/status` (ISO + human dates, `etaHuman`, `rateHuman`),
`/disk-usage` (`bytesHuman`), `/ops` (`tsHuman`, `msHuman`), `/generate` (`msHuman`).
- **Admin module rewritten with Directus UI kit** (`v-button`, `v-input`, `v-checkbox`, `v-select`,
`v-notice`, `v-progress-linear`), field explanations, preset table with effective formats + shadow
warnings, storage table, error column in Recent operations, and a full collapsible **API reference**.
- **Run now** now ignores the maintenance window; **Cancel** only renders while a run is active.
- **Dimension vs file size clarified** in README/goal/AGENTS: the 6000 limit is a pixel-dimension guard in
Directus, not a file-size limit; the extension imposes none.
- Tests: **40/40** pass; typecheck clean; build OK.
### Still open
- Admin module UI not yet verified in a real browser (bundle + entries registered; rendering/polling untested).
- Cancel + concurrent-run 409 not exercised end-to-end.
- Staging deploy not executed (scripts/templates provided); prod rollout not done.
- F01/F02/F07/F10 remain `passes:false`.

Tested against Directus **11.17.4** (self-hosted, PM2 cluster, local disk storage). The manifest targets

silently killed the upload hook.
- **Docker bind mounts**: never `rm -rf` the bind-mounted extension directory — it breaks the mount and
Directus removes the extension without re-adding it. Sync contents in place; restart the dev container.
- The dev stack (`dev/compose.dev.yml`) is the only place to test; never load this into prod while
iterating (prod has `EXTENSIONS_AUTO_RELOAD=true`).
## Server facts (land-nest)
- Directus image `directus/directus:11.17.4`; `PUBLIC_URL=https://data.landshaft.life`;
`PM2_INSTANCES=8`; `STORAGE_LOCAL_ROOT=./uploads`; logs at `~/apps/directus/logs`.
- `ASSETS_TRANSFORM_MAX_CONCURRENT=45` per worker → over it errors; catch per file/preset.
- `ASSETS_TRANSFORM_IMAGE_MAX_DIMENSION` default 6000 is a **pixel dimension** guard, not a file-size
limit. The extension imposes no limit; raise the Directus env var to process larger images.
- Local storage writes are **non-atomic** — warm only after an upload is committed.
- `RATE_LIMITER_*` applies to HTTP only → irrelevant to in-process generation (this is why the admin
knob is *concurrency*, not a rate limit).
- Observed bottleneck (2026-10-23 log triage): `storage:local:responseTime 1206ms`,
`pg:responseTime` 150–738ms; **no** 503s, **no** sharp errors. Pre-generation removes the
cold-transform cost; uploads-volume I/O latency is a separate ops concern.
## Safety (do not crash prod)
- Every entrypoint body is wrapped so thrown errors are logged and swallowed — never propagate into
Directus core. ALL behaviour is gated by `enabled` (default **false**): a loaded-but-disabled bundle
does nothing.
- Test only on the **staging** stack (`dev/compose.dev.yml`), never the prod instance.
- Rollout = backup previous `dist/` → deploy → healthcheck → enable; rollback = restore `dist/` + disable.
- Automation (autonomous loops) gets **staging only**: a scoped token limited to `/image-previews/*`
(+ `directus_files` metadata read), never a prod admin token; never the prod Docker socket; restricted
non-sudo SSH or opencode-on-host. Promotion to prod is a human action.
- **Dimension vs file size**: `ASSETS_TRANSFORM_IMAGE_MAX_DIMENSION` (default 6000) is a **pixel
dimension** guard in Directus, not a file-size limit. The extension imposes no limit; raise the
Directus env var to process larger images.
- **Unsupported preset formats** (e.g. `bmp`) fail at generation; surface the error in `/ops` and the
module's Recent operations.
- The dev stack (`dev/compose.dev.yml`) is the only place to test; never load this into a production
instance while iterating (production may have `EXTENSIONS_AUTO_RELOAD=true`).
## Conventions
- Build via `@directus/extensions-sdk` (`npm run build` / `dev` / `link`); bundle emits `dist/app.js` + `dist/api.js`.
- Deploy with `npm run publish` (scp `dist` + `package.json` to land-nest extensions dir).
- Deploy by copying `dist/` + `package.json` into the Directus extensions dir (see README); a staging
helper lives in `dev/deploy-staging.sh`.
- Tests: `node:test` via `tsx` (`npm test`). Typecheck: `npm run typecheck`.
- Do not add comments unless asked. Follow the sibling extensions' style.
- Never commit without explicit request.

Target: self-hosted Directus **11.17.4** (PM2 cluster, local disk storage).
## Requirements
## Why this approach (read AGENTS.md too)
- Directus **11.x** (tested on **11.17.4**).
- Node 18+.
- A **non-sandboxed** local extension (it uses Directus's internal services at runtime — see
Compatibility).
- Local disk storage is supported out of the box; other storage drivers work for disk reporting through
the Directus storage manager.
## Why this approach
The cache file is `<filename_disk>__<object-hash(resolved transforms)>.<ext>`. The hash depends on the
RESOLVED transforms, and every `system-*` preset is `format:'auto'` — which resolves differently
server-side (jpg/png) than in a browser (avif). We therefore generate **in-process** with an explicit
`acceptFormat` (`avif` + `webp`), reproducing the browser's cache file byte-for-byte without any HTTP
request. Naive warming (or the popular community extension) silently misses.

## Install / build / publish
## Install
```bash
git clone https://code.at.locus.im/Rawman/directus-extension-generate-image-previews.git
cd directus-extension-generate-image-previews
npm install
npm run build
```
Copy the build into your Directus extensions directory:
```bash
cp -r dist package.json /path/to/directus/extensions/directus-extension-generate-image-previews/

Restart Directus (or let `EXTENSIONS_AUTO_RELOAD` pick it up). The **Image Previews** module appears in
the admin sidebar.

## Compatibility
Tested against Directus **11.17.4**. The extension reads Directus's own transform pipeline and storage
manager (`@directus/api/utils/transformations`, `@directus/api/storage/index`) via runtime imports; these
are **not a public API** and may change between Directus versions. Re-verify after a Directus upgrade,
especially the hash-match gate (`resolve-plan` vs a real browser asset request).
The extension is not sandboxed: Directus's sandbox forbids importing anything except `directus:api`, which
this extension needs for storage/transform access.

# Security
## Access model
- Every `/image-previews/*` endpoint requires an authenticated **Directus admin** (session or admin
token). Non-admin requests receive `403`.
- The admin module is only reachable from the Directus admin app.
- There is no separate token mechanism and no unauthenticated write path.
## Operational guidance
- Do not expose a production admin token to automation. For autonomous/remote workflows, use a staging
instance and least-privilege access.
- The extension generates transforms in-process; it does not accept image URLs or arbitrary file paths
from clients.
- Persisted state lives under `<STORAGE_LOCAL_ROOT>/.image-previews` and contains no secrets.
- Uploaded file contents are never logged; only file ids, preset keys, formats, timings, and error
messages.
## Reporting a vulnerability
Please report security issues privately to **rawman@locus.im** rather than opening a public issue.
