Sharp 0.35.1 moved FormatEnum to a namespace export and removed "avif"
from FormatEnum (now a separate literal in toFormat). BullMQ 5.78.1
bundles ioredis 5.10.1 while we have 5.11.1, causing structural type
mismatch. Also fixes new Biome 1.9 lint rules.
getSnapshot() was calling JSON.parse() on every invocation, returning
a new array reference each time. useSyncExternalStore uses Object.is
comparison, so it saw a "new" value on every render and triggered
an infinite update loop. Fix by caching the parsed result and only
re-parsing when the raw localStorage value changes.
Handle MFA challenge in login flow (TOTP code input after password
verification, recovery code hint, back navigation). Add admin security
settings section with session idle timeout, max sessions per user,
MFA policy selector, SSO enforcement toggle with break-glass username,
and password policy controls. Propagate new i18n keys to all 21 locales.

When AUTH_ENABLED=false, the anonymous user was assigned the "user" role
which lacks settings:write permission, making all settings saves return
403. Since no admin exists when auth is disabled, settings were
permanently read-only. Promote the anonymous user to "admin" so the
single user has full control of the instance.
Also adds DEFAULT_TOOL_VIEW env var (sidebar|fullscreen) following the
existing DEFAULT_THEME pattern, seeded via ensureDefaultSettings() on
first boot.
Closes#135
- Fix dispatcher pipe deadlock: drain stdout pipe in a background thread
to prevent blocking when ONNX runtime output exceeds 64KB pipe buffer
- Add 5-minute SSE stall timeout so the UI shows an error instead of
hanging forever when async AI processing stalls
- Guard CPU colorization: skip for images >2MP on CPU and when DDColor
model is not installed, with clear user-facing messages
- Add AVIF decode fallback via ImageMagick for bitstream variants that
Sharp's bundled libheif cannot decode (affects all tools)
The vectorize tool had a custom processing flow that bypassed the
standard useToolProcessor hook -- no progress indication, no server-side
batch, and the Download All ZIP relied on a client-side sequential loop.
Backend: extract core logic into vectorizeBuffer(), register via
registerToolProcessFn() so the /batch endpoint works with p-queue
concurrency and SSE progress events.
Frontend: replace custom fetch loop with useToolProcessor hook and
ProgressCard, giving upload progress, per-file batch status, and
automatic Download All ZIP via the existing tool-page infrastructure.
Also set image/svg+xml MIME type on SVG blobs during batch ZIP
extraction to ensure reliable rendering in <img> tags across browsers.
The X-File-Results header contained raw JSON with non-ASCII characters
from filenames (Chinese, Japanese, etc.), violating RFC 7230. Node.js
threw ERR_INVALID_CHAR on writeHead(). Fixed by wrapping the JSON in
encodeURIComponent() on the backend and decodeURIComponent() on the
frontend, ensuring only ASCII goes into the header while preserving
the original filenames after decoding.

The install prompt and error messages were showing the underlying AI
bundle name (e.g. "Background Removal") instead of the actual tool name
(e.g. "Passport Photo"). Now the UI shows the correct tool name and
description while still installing the correct bundle behind the scenes.
Closes#130
1. Export dialog (Ctrl+Shift+S): replaced react-hotkeys-hook handler with
a capture-phase keydown listener on window so the browser's native
"Save Page As" dialog is intercepted before it can fire.
2. Text tool: created useTextTool hook that spawns an inline textarea
overlay on canvas click, commits the text as a Konva Text object on
blur/Enter, and wired it into the useActiveToolHandlers dispatcher.
3. Undo (Ctrl+Z): removed the 500ms debounce from zundo's handleSet.
The debounce caused a race where calling undo before the timer fired
would discard the future-states stack, making undo appear to do
nothing. The equality function (keyed on _historyVersion) already
prevents intermediate states from being recorded, so the debounce
was redundant.
Implement Agent 7 features for the image editor:
- History panel with undo/redo list, action icons, and state jumping
- 51+ keyboard shortcuts via react-hotkeys-hook (tools, modifiers, clipboard)
- Export dialog with PNG/JPEG/WebP format, quality, resize, clipboard copy
- Navigator minimap with viewport rectangle, drag-to-pan, zoom slider
- Autosave/recovery system with localStorage and recovery banner
- Project save/load (.snapotter JSON format)
- Unsaved changes warning via beforeunload
- Paste from system clipboard support
Convert all 9 AI tool routes (colorize, restore-photo, remove-background,
enhance-faces, blur-faces, red-eye-removal, erase-object, noise-removal,
upscale) to async 202 processing so none are vulnerable to proxy
connection timeouts.
Also fixes:
- Replace basename() with sanitizeFilename() in all AI tool routes
(prevents double-extension attacks and adds length truncation)
- Add UUID format validation for clientJobId field
- Fix missing filename sanitization in noise-removal (was using raw
user-supplied filename with zero sanitization)
- Remove em dash from error message in use-tool-processor
The upscale route held the HTTP connection open for the full duration of
Python sidecar processing (30-300s). Behind proxies with connection
timeouts (Cloudflare Tunnel: 100s), this caused HTTP 524 errors.
The route now returns 202 Accepted immediately after upload validation
and processes in the background. The result (downloadUrl, sizes, etc.)
is delivered via the existing SSE progress channel. The frontend detects
the 202 and waits for the SSE completion event instead of reading the
XHR response body. A reconnect-safe completion store ensures results
survive brief SSE disconnects.
Closes#106
- Add Cloudflare Pages deployment for landing page (snapotter.com) and
docs (docs.snapotter.com)
- Create deploy-landing.yml and update deploy-docs.yml workflows
- Update CI to ignore apps/landing/** paths
- Fix logo transparency (remove white background) across all apps
- Recreate social-preview.png with SnapOtter branding
- Update all docs URLs from GitHub Pages to docs.snapotter.com
- Update VitePress config: light theme default, fix llms.txt paths
- Add .vitepress/cache/ and .env.* to gitignore
When auth was disabled, the backend middleware attached the first admin
user from the database to every request, and the frontend granted all 12
permissions. This gave every unauthenticated visitor full admin access
to user management, settings, teams, branding, and feature installation.
Now both layers use role "user" with user-level permissions so tools,
files, and pipelines still work without login while admin-only routes
correctly return 403.
Closes#72
Guard startPolling in handleOnline to only fire when transitioning from
offline state. Previously, a spurious browser online event while already
connected would start a polling interval that never gets cleared.
