From f9b6720d15eb2ca6be2af0b945e8b5712df23672 Mon Sep 17 00:00:00 2001 From: Till JS Date: Fri, 10 Apr 2026 22:17:57 +0200 Subject: [PATCH] feat: E2E smoke test, lazy widget loading, typed module context MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Three medium-sized improvements: 1. E2E Smoke Test (e2e/smoke.spec.ts) Two Playwright tests that exercise the critical happy path: - "boot → dashboard → navigate → verify": opens /, /todo, /notes, /habits, /calc in sequence, verifies each renders content, checks for console errors. - "module routing: all core routes respond": iterates 11 core routes (/todo, /calendar, /contacts, /notes, /habits, /calc, /chat, /body, /dreams, /finance, /moodlit) and asserts no SvelteKit error page or crash. Runs in guest mode using the existing dismissWelcomeModal helper. 2. Lazy Widget Loading (WidgetContainer.svelte) Dashboard widgets are now lazy-mounted via IntersectionObserver. Offscreen widgets render a small pulse placeholder until they scroll into the viewport (with 200px rootMargin for pre-loading). Once visible, the widget stays mounted permanently. This defers liveQuery subscriptions for the ~13 dashboard widgets so only the ~3-4 above-the-fold widgets fire IndexedDB reads on initial mount — the rest activate as the user scrolls. 3. Typed Module Context (lib/data/module-context.ts) `createModuleContext(key)` returns a `{ provide, consume }` pair that wraps Svelte's setContext/getContext with compile-time type safety. Replaces the manual `getContext<{readonly value: T[]}>('key')` pattern that was duplicated across every layout/page boundary with a fragile inline type annotation. Example usage added for the body module (body/context.ts) — other modules can adopt incrementally. Turborepo type-check task was already in place (turbo.json + root package.json). No changes needed.
