alexei.dolgolyov 2be608ba95 feat(cache): thumbhash-validated asset cache + settings UX overhaul
Cache engine:
- TelegramFileCache: configurable max_entries (LRU cap applies in both TTL
  and thumbhash modes), ttl_seconds<=0 disables TTL, stats() method.
- Dispatcher builds an asset.id -> thumbhash resolver from event.added_assets
  (Immich populates thumbhash in extra) and passes it to TelegramClient, so
  asset-cache entries invalidate on visual change rather than age.
- Watcher wires app settings into cache init: URL cache = TTL + LRU cap,
  asset cache = thumbhash + LRU cap. Adds soft-reset (in-memory only) used
  when cache params change.

Settings:
- New key telegram_asset_cache_max_entries (default 5000).
- telegram_cache_ttl_hours default bumped 48 -> 720 (30d); now URL-only.
- PUT /settings resets in-memory caches when cache keys change (files kept).
- New endpoints: GET/POST /settings/telegram-cache/stats and /clear.

Settings page:
- Cache stats card (count + size + oldest/newest per bucket) with a hint
  explaining that the size is cumulative uploaded-to-Telegram bytes.
- Clear-cache button behind a confirm modal.
- New TimezoneSelector + LocaleSelector components replace raw inputs.
- max-entries input, TTL range updated (0..8760, 0 = disabled).

Mobile nav:
- "More" panel now mirrors the full sidebar tree (groups + subnodes) so
  every destination is reachable on mobile; previously flat hand-picked list.
- Nav height uses env(safe-area-inset-bottom); panel bottom + z-index fixed
  so content can't visually overlay the bottom bar.

A11y / DOM warnings:
- Password-change form has a hidden username field for password-manager
  association; autocomplete hints on all three password inputs.
- Telegram webhook secret wrapped in a no-op form + autocomplete=off.

Bug fix:
- update_settings used any(await ... for ...) which raised TypeError at
  runtime (async generator not an iterator); replaced with explicit loop.

Notify Bridge

A generic bridge between service providers and notification targets.

Notify Bridge monitors services (like Immich photo servers) for changes and dispatches notifications to configurable targets (Telegram, webhooks) using customizable templates.

Architecture

  • Service Providers — Connectors to external services (Immich, more coming)
  • Trackers — Monitor specific collections within a provider for changes
  • Tracking Configs — Define what events to watch for and scheduling rules
  • Notification Targets — Where to send notifications (Telegram chats, webhook URLs)
  • Template Configs — Jinja2 templates that format notifications per provider type

Project Structure

packages/
  core/       — Shared library: providers, models, notifications, templates
  server/     — FastAPI REST server with SQLite database
frontend/     — SvelteKit dashboard (Svelte 5, Tailwind CSS v4)

Quick Docker Deploy

docker run -d \
  --name notify-bridge \
  --restart unless-stopped \
  -p 8420:8420 \
  -v notify-bridge-data:/data \
  -e NOTIFY_BRIDGE_SECRET_KEY=$(openssl rand -hex 32) \
  git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge:latest

Then open http://localhost:8420 in your browser.

Environment Variables

Variable Required Default Description
NOTIFY_BRIDGE_SECRET_KEY Yes Secret key for JWT tokens (min 32 chars)
NOTIFY_BRIDGE_PORT No 8420 Server listen port
NOTIFY_BRIDGE_CORS_ALLOWED_ORIGINS No * Comma-separated allowed CORS origins
NOTIFY_BRIDGE_DEBUG No false Enable debug logging

Docker Compose

services:
  notify-bridge:
    image: git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge:latest
    container_name: notify-bridge
    restart: unless-stopped
    ports:
      - "8420:8420"
