# React Development > Optimized for React 19+, TypeScript 5.5+, React Testing Library 16+, and modern server-first app architectures. Expert guidance for building high-quality React applications with React 19+, modern hooks, TypeScript, and best practices following official React documentation at https://react.dev. - Leverage native parallel subagent dispatch and 200k+ context windows where available. ## Component Review Rubric Reference Apply the shared [Component Review Rubric](../frontend-design/SKILL.md#component-review-rubric) before approving React components, then run the React-specific checks below. ## Anti-Patterns - Fetching everything in client effects by default: Server-first data loading is usually simpler, faster, and easier to cache. - Adding memoization before profiling: Manual optimizations can create stale-prop bugs and hide simpler design fixes. - Skipping keyboard and accessible-name review: A component is not done if only pointer users can operate it reliably. ## Verification Protocol Before claiming "skill applied successfully": 1. Pass/fail: The React Development guidance is tied to a concrete route, component, screen, or design artifact. 2. Pass/fail: Component states cover loading, empty, error, success, and responsive breakpoints where applicable. 3. Pass/fail: Accessibility, visual hierarchy, and interaction behavior are reviewed against the shared component rubric. 4. Pressure-test scenario: Review the component on a narrow mobile viewpo
