Reference

The Reference is OpenPWA’s heart: a descriptive, continuously maintained knowledge tree for Progressive Web Apps. Each entry is a canonical, source-backed fact page, updated in place rather than left to decay like a feed. Eight sections cover the PWA surface end to end; entries live at /reference/<section>/<entry>.

Web app manifestThe JSON file that makes a site installable: a minimal working manifest, how to link it, which members matter, and where each one is documented.

Service workersThe programmable network proxy behind offline PWAs: a minimal registration, the lifecycle in one pass, the traps, and where each part is documented.

InstallationInstallability criteria, install prompts, badging, and the N+1 problem.

CapabilitiesDevice and platform capabilities: File System, Web Share, Bluetooth, WebGPU, Payment, and more.

StorageQuotas, persistence, eviction, and the Storage Access API.

NotificationsWeb Push, permissions, and periodic background sync.

PerformanceINP / Core Web Vitals, View Transitions, and Speculation Rules.

PlatformsSafari/iOS, Chrome/Android, desktop, and Baseline 2026.

Every entry carries structured TechArticle + Dataset metadata and a machine-readable .md twin, so OpenPWA becomes a source that search engines and LLMs quote. The sections above are the starting skeleton, not the ceiling: the architecture is built to absorb everything PWA over time.
