Engineering Patterns

Selective Hydration

Leveraging Intersection Observer to defer React hydration, reducing Main Thread blockage for a faster TBT.

Streaming Suspense

Utilizing server-side streaming to progressively deliver HTML units, providing immediate visual feedback via Skeletons.

Feature-First Logic

Domain-driven design folder structure ensuring scalability and strict separation between UI and business services.
