SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

React 19 introduces Server Components, concurrent features, and a modern toolchain that can be hard to adopt. This skill provides a structured guide to help developers apply these patterns consistently across projects.

Core Features & Use Cases

  • Server Components: Build server-rendered components that reduce client bundle sizes and enable direct data access.
  • Hooks & Patterns: Effective use of useState, useEffect, useTransition, useOptimistic, and new APIs for scalable UI.
  • Server Functions & Actions: Implement server functions and client-server interactions with form actions and data fetching strategies.
  • Performance Best Practices: Guidance on memoization, code splitting, and streaming content for responsive apps.

Quick Start

Use this skill to scaffold a minimal React 19 client and server component example, including a server component rendering data and a client component with interactivity.

Frequently Asked Questions about react

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do React 19 server components reduce client bundle sizes?▼

React 19 server components reduce client bundle sizes by rendering on the server and enabling direct data access, sending only HTML and JavaScript for interactive client components to the browser.

What is the best way to use useTransition and useOptimistic hooks in React 19?▼

The best way to use useTransition and useOptimistic hooks is for scalable UI interactions, applying these new React 19 APIs to manage concurrent rendering and provide immediate feedback during data mutations.

How do I implement server functions and actions for client-server interactions?▼

You implement server functions and actions by handling client-server interactions through form actions and data fetching strategies, executing logic securely on the server and updating the UI without manual API wiring.

Can I use TypeScript with React 19 server components and server actions?▼

Yes, you can use TypeScript with React 19 server components and server actions. The skill enforces TypeScript usage to apply server component rules, server actions, and references with consistent type safety.

When do I need memoization and code splitting for React 19 performance tuning?▼

You need memoization and code splitting for React 19 performance tuning when optimizing component composition and streaming content across client and server boundaries to keep apps responsive.

What's the best way to scaffold a minimal React 19 server and client component app?▼

The best way to scaffold a minimal React 19 app is structuring a server component for direct data rendering alongside a client component for interactivity, establishing clear boundaries for server-driven rendering.
