Transitional apps samples elements from both traditional and modern architecture. The term is borrowed from interior design’s framing of “transitional design.” Transitional apps are, like multi-page apps, server-side rendered for fast initial loads, resilient since they work without JS by default, and provide a consistent experience with accessibility features built in. But like a single-page application, they also have a single codebase, fast navigation, persistent elements, and client-side state management.
