SSR vs PWA for SEO-critical offline applications

Integration Mode Trade-offs

When architecting a Quasar application that requires both high search-engine visibility and offline capabilities, the choice between Server-Side Rendering (SSR) and Progressive Web App (PWA) modes presents a conflict in build configuration. SSR improves the time-to-first-paint and SEO by rendering pages on the server, while PWA mode leverages service workers for caching and offline access.

Because these modes are configured as distinct framework extras in quasar.conf.js, selecting one often prioritizes a specific user experience at the expense of the other. In a test environment lacking production credentials, verifying the interaction between server-side hydration and service worker caching becomes a primary architectural concern.

Which mode is more sustainable for an application that must maintain SEO rankings while providing offline functionality? What are the implications of prioritizing PWA caching over SSR rendering for initial page loads?
