Security
- Fix path traversal in GET /api/archives/:name/files. Express decodes route
params after segment matching, so `..%2f..%2fetc` escaped ARCHIVES_DIR and
returned a recursive listing of arbitrary directories.
- Add CSP and baseline security headers; disable x-powered-by.
- Stop baking GEMINI_API_KEY into the client bundle (the SDK was unused).
- Run the container as `node` instead of root.
Performance
- Add a directory-mtime-keyed archive index, warmed in the background and
persisted. Listing 110k files went from ~52s to ~0.1s; the largest archive
(24k files) serves in ~0.3s. Per-file stat over CIFS costs ~1.4ms and does
not parallelise, so it is now done once rather than per request.
- Build media URLs from the File directly instead of
`new Blob([await file.arrayBuffer()])`, which read every media file fully
into memory (a 20GB archive tried to become 20GB of resident blobs).
- Track and revoke object URLs; previously none were ever revoked.
- Give `requestThumbnail` a stable identity so a completed thumbnail stops
re-running the effect in every mounted thumbnail.
- Namespace IndexedDB keys so listing archives no longer deserializes every
cached thumbnail blob, and thumbnails no longer collide across archives.
- Serve real file sizes: RemoteArchiveFile was constructed with size 0, which
silently disabled high-res thumbnailing for every server archive.
Correctness
- Local archives cached media as blob: URLs, which die with the document, so
a cached local archive restored as an archive of broken images. Media now
carries a stable path and is rehydrated from a persisted directory handle
(File System Access API), falling back to re-prompting for the folder.
- Fix permalinks: the URL-writing effect erased ?a= on mount before the
archive list arrived to consume it, so deep links never resolved.
- Make cache invalidation detect nested changes via a directory signature.
- Add an error boundary and tolerate unparseable dates, which previously
threw a RangeError and blanked the app.
- Default video to muted so autoplay is not blocked by Safari/Firefox.
Features
- Fold sidecar directories into their base profile: `<user> - reels`,
`story - <user>` and `story highlights - <user> - <title>` now appear as
reels, the story ring and Instagram-style highlight circles rather than as
separate archives.
Housekeeping
- Add @types/react; React was previously type-checked against its JavaScript
source, so `npm run lint` gave almost no type safety on components.
- Vendor fonts and PWA icons locally; the app made third-party CDN requests
despite advertising offline support and local-only processing.
- Drop unused better-sqlite3 (a native module that broke `npm install`).
- Add vitest with 36 tests over the filename and directory-naming rules.

Key changes:
- Enabled full metadata caching for local folder archives, allowing them to load instantly from IndexedDB without re-uploading.
- Implemented oldest-image fallback for profiles missing an explicit profile picture.
- Restored folder-name-to-username detection for local archive uploads.
- Optimized scan indexing to track all image files for fallback use.
Key changes:
- Corrected logic in PostThumbnail to prevent blur effects on images smaller than 1MiB.
- Restored the white glass aesthetic to the scanning dashboard with improved contrast and transparency.
- Optimized scanning background transitions to ensure a smooth, flicker-free crossfade.
Key changes:
- Added Web Worker for background image thumbnailing with a 1MiB threshold to optimize CPU/memory usage.
- Implemented a serial task queue for memory-safe high-res image processing, preventing OOM crashes.
- Added inter-post preloading in the modal for seamless 'Previous/Next' navigation.
- Refined scanning UI with double-buffering and a dark background to completely eliminate white flashes.
- Renamed project to 'instaarchive-viewer' in package.json.
- Fixed 'Open image in new tab' by denylisting /archives and /api in PWA config.
Summary of changes:
- Extracted archive scanning logic into a modular 'useArchiveScanner' hook for better maintainability and performance.
- Refined PostModal carousel with intelligent media preloading and smoother, jitter-free transitions.
- Optimized image rendering with 'decoding=async' and removed 'black flashes' between slide changes.
- Updated PWA configuration to 'autoUpdate' with hourly periodic checks for fresh content.
- Fixed several bugs including stories sorting, permalink parameter cleanup, and profile metadata cache restoration.
- Comprehensive updates to documentation (README.md and GEMINI.md) reflecting the new architecture.
