Reader, Responsiveness, and PWA
Reader
Section titled “Reader”Leitura.jsx selects a capability by format. ReaderShell standardizes opening, error, retry, and closing states. The overlaid dock remains visible on desktop/mobile and contains navigation, page controls, and close.
PDF.js receives a Worker created by the Vite bundle, avoiding a .mjs MIME dependency. EPUB/MOBI are normalized into pages/content; comics request images on demand. Cleanup cancels tasks, destroys documents, clears canvases, and revokes Object URLs.
Touch, click, and keyboard are supported. The full page is fitted to the viewport; the page-turn animation was removed.
public/sw.js uses versioned caches. Navigation and catalog are network-first; covers/assets use stale-while-revalidate with limits. Book payloads are excluded from automatic caching. offlineLibrary.js downloads content only after explicit action and records metadata in IndexedDB.
The shell has a manifest, icon, and offline fallback. When policies change, increment CACHE_VERSION and run PWA/E2E tests.
AppErrorBoundary handles global failures. Queries show loading/error/retry; readers show a specific error instead of a blank screen; toasts communicate operations. Code cancels asynchronous work on unmount where applicable.
