Features Overview

Catalyst is built around a small set of framework capabilities that work together: SSR, route-aware data loading, a shared web and mobile application model, and production-oriented configuration.

Server-Side Rendering​

  • SSR is enabled by default for every route.
  • Improves first load performance and crawlability.
  • Supports data hydration for smooth client navigation.

Universal App Delivery​

  • Build web, iOS, and Android apps from one React codebase.
  • Keep shared business logic while allowing platform-specific UI when needed.
  • Use one project for browser and native app delivery with consistent cache behavior across platforms.

Routing And Layouts​

  • Route configuration with nested layouts.
  • Predictable SSR + client navigation behavior.
  • Clean separation of page and shell concerns.

Data Fetching Model​

  • serverFetcher for SSR data.
  • clientFetcher for post-hydration transitions and refresh.
  • Route-level data access hooks.

Native Device APIs​

  • Camera, files, storage, haptics, notifications, and device info.
  • Unified usage model through hooks.
  • Platform-aware behavior across Web, iOS, and Android.

Performance And Reliability​

  • Cache bundled static assets in universal apps, such as JS, CSS, images, and other files matched by cachePattern, to improve startup and repeat-load speed.
  • Reuse fetched route data on the client through the serverFetcher and clientFetcher flow so navigation stays fast after hydration.
  • Store app-level data in device storage when needed for persistence, offline resilience, and faster resume behavior.

Build And Deployment Readiness​

  • Optimized production bundles.
  • Catalyst app deployment and universal app deployment paths.
  • Android build optimization support.
