How to score 100 on a Angular Progressive Web App Audit
summary
Claims a path to 100% on a Progressive Web App audit by using Angular tooling and concrete steps: scaffold with the CLI, run ng add @angular/pwa to generate a service worker and manifest, add icons and meta tags, and define asset and data groups with explicit caching strategies (installMode prefetch, networkFirst vs performance) for APIs. Baseline Angular apps score ~30% on Lighthouse; the demo app is hosted on HTTPS (Firebase) and the audit shows the checklist items becoming compliant.
