Architectural Scenarios

Target Seniority Level

Staff UI Architect

Network Strategy: Cursor-based pagination (limit=20, cursor=timestamp_id) with 2-page speculative prefetch.

Functional & Non-Functional Requirements

Functional

Smooth infinite scrolling in both directions with anchor preservation.
Dynamic height estimation and resize observer measurements.
Lazy media decoding (images/videos only decoded when within viewport buffer).
Optimistic interactions (instant like, bookmark, and comments).

Non-Functional

Fixed DOM node count (max 30-50 nodes rendered regardless of scroll depth).
Zero Cumulative Layout Shift (CLS) when off-screen items resize.
60fps scroll performance on throttled mobile devices (INP < 100ms).
Clean memory reclamation on item unmount.

State Architecture Split

Server:Paginated cursor cache (TanStack Query / SWR) keyed by [feed, cursor].

Client:Scroll index offset, dynamic item height measurement map (Map<id, number>).

Ephemeral:Active scroll velocity, touching pointers, gesture deceleration.

Performance & Hardware Acceleration

DOM node recycling with absolute top-offset transforms.

ResizeObserver batching to measure dynamic content without layout thrashing.

IntersectionObserver viewport buffer (500px overscan) for zero blank frames.
