Build-time image optimization plus auth-gated private content.
- <Image> (src/lib/components/Image.svelte): wraps @sveltejs/enhanced-img
for public images under src/lib/assets/images/ (AVIF/WebP, multiple
widths, lazy by default), plus a `private` mode for auth-gated images.
- Private images: scripts/build-private-images.ts encodes sources from
src/lib/assets/private-images/ into private-assets/ (outside the bundle)
and a manifest; served only via the auth-checked /private-images/
endpoint (X-Accel-Redirect in prod, disk read in dev).
- HikeImage gains a `src` prose mode: build-hikes encodes non-waypoint
images referenced in .svx and exposes them by filename (imagesByName);
a `private` attr routes them through the gated /hikes/<slug>/private/ path.
- <Private> (src/lib/components/Private.svelte): renders prose only to
logged-in viewers (cosmetic gating — text still ships in the bundle).
- deploy.sh rsyncs private-assets/; prod needs an nginx internal
/protected-images/ location.
Build pipeline (scripts/build-hikes.ts) parses per-hike GPX, encodes
images via sharp, reverse-geocodes the centroid against Swisstopo and
emits a typed manifest under src/lib/data/hikes.generated.ts (gitignored).
Track JSON + image binaries live outside /static; served in dev by a
small hike-images plugin in vite.config.ts, in prod by nginx (private/
images proxied through Node + X-Accel-Redirect for auth-gating).
/hikes overview: full-bleed Swisstopo hero map (HikesOverviewMap) sits
under the sticky nav, drawing one polyline per route coloured by SAC
tier (T1 yellow Wegweiser, T2/T3 white-red-white, T4-T6 white-blue-
white). Click navigates, hover thickens + tooltips. Layer toggle,
recenter, GPS controls mirror the detail map (minus images toggle).
Cards drop the trail SVG, gain a per-route icon + SAC marker
pictogram on the cover, altitude range, season label, and "Neu" badge
for recently-published hikes. Filter bar + totals strip recompute over
the currently-visible set.
/hikes/[slug]: hero map with elevation profile, photo strip with map
sync, scroll-position pin, GPX download, SAC marker stats + min/max
altitude + season.
Route-builder (/hikes/route-builder): client-side draft persisted to
localStorage, EXIF-driven image placement, snap-to-route via BRouter
(OSRM + linear fallback) and Swisstopo profile.json elevation
enrichment that handles degenerate same-coord segments via the height
endpoint.
Filter init switched from a script-time snapshot of data.hikes (which
sporadically returned a one-hike subset during dev hydration and
locked the page to that single hike) to a post-mount \$effect.
Content under src/content/hikes/ intentionally not included (WIP).
Lightning CSS was deduplicating manually written backdrop-filter +
-webkit-backdrop-filter to just the webkit version, breaking blur on
Firefox. Remove manual webkit prefixes and let Lightning CSS auto-prefix
via browser targets in vite.config.ts.
- Exclude barcode-detector from Vite optimizeDeps to prevent WASM mangling
- Self-host ZXing WASM via Vite ?url import with prepareZXingModule
- Use barcode-detector/ponyfill instead of deprecated /pure export
- Separate barcode-detector/zxing-wasm into own chunk
- Add CAMERA permission to Android manifest for Tauri app
- Move HTML stripping to server-side to remove cheerio from client bundle (247KB reduction)
- Add terser minification with console/debugger removal
- Enable manual code chunking for chart.js and auth libraries
- Convert TTF fonts to WOFF2 format (~900KB savings)
- Enable brotli/gzip precompression in adapter
- Update CSS to prefer WOFF2 with TTF fallback
