Cold-start bundle was a single 1.88 MB / 577 KB-gzipped chunk that
parsed every page in the app before first paint, including pages a
typical session never opens.
Two-part fix:
1. Lazy-load 10 rarely-visited pages via React.lazy() — each becomes
its own chunk that only downloads when the route is hit:
Settings, Statistics, Help, WhatsNew, DeviceSync, OfflineLibrary,
LabelAlbums, AdvancedSearch, FolderBrowser, InternetRadio.
Whole <Routes> tree is wrapped in <Suspense fallback={null}> — no
visible loading state, the browser cache hits on subsequent visits.
2. Vite manualChunks splits dependencies that change rarely from app
code: react/react-dom/react-router, the @tauri-apps/* family, and
i18next. Tauri auto-updater pulls smaller deltas when only app
code changed (vendor chunks stay byte-identical and cached).
Build output:
Before: 1.88 MB / 577 KB gz monolithic
After cold start: ~450 KB gz (index 370 + react 54 + tauri 6 + i18n 20)
= 22% smaller initial download
Plus 11 lazy chunks. Notably WhatsNew's bundled CHANGELOG (215 KB /
76 KB gz) is now off the cold-start path entirely.
