Async Boundary Optimization (React 18)

Summary

Optimize async boundaries to balance responsiveness, streaming, and error containment.

Key Capabilities

• Place Suspense boundaries to minimize waterfalling.
• Use error boundaries for targeted recovery.
• Coordinate async boundaries with data prefetching.

PhD-Level Challenges

• Compute boundary placement as an optimization problem.
• Formalize error containment guarantees across boundaries.
• Evaluate boundary placement under changing network profiles.

Acceptance Criteria

• Provide boundary placement analysis with metrics.
• Demonstrate reduced waterfalling in data loading.
• Document error containment behavior.
