SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

React 19 patterns with React Compiler aims to reduce the need for manual memoization by delegating optimization to the compiler, enabling more predictable renders and simpler component code.

Core Features & Use Cases

  • No Manual Memoization: rely on React Compiler optimizations rather than useMemo/useCallback.
  • Imports & Component Boundaries: promote named imports and clear server/client boundaries.
  • Server Components First: default server components with client components only when interactive features are required.
  • use client guidance: identify when to enable client behavior for state, effects, or event handling.
  • use() Hook & server actions: support promise handling and server interactions in UI code.
  • ref as Prop approach: treat ref as a normal prop in line with the pattern.
  • Keywords emphasize patterns like server components, compiler optimization, and modern hooks.

Quick Start

Create a React 19 component that uses a server-first pattern and a minimal client component for interactivity.

FAQPage Schema
How does the React Compiler eliminate manual memoization in React 19?

The React Compiler automatically optimizes component performance by handling memoization internally, allowing you to remove manual useMemo and useCallback hooks for more predictable renders and simpler component code.

How do I set up server components with selective client components in React 19?

Set up React 19 server components by default and use the 'use client' directive only when interactive features are required for state, effects, or event handling, enforcing clear server/client boundaries.

When do I need the use client directive for React 19 components?

You need the 'use client' directive to enable client behavior for components requiring state management, effects, or event handling, keeping the rest of your UI as server components.

Can I use the use() hook for promise handling in React 19 server actions?

Yes, the use() hook supports promise handling and server interactions within UI code, streamlining how React 19 components manage asynchronous server actions and data fetching.

Do I still need useCallback if I am using the React Compiler?

No, you do not need useCallback or useMemo when using the React Compiler, as it handles optimization automatically to ensure predictable renders without manual memoization functions.
