React Specialist
Kanitsal Cerceve (Evidential Frame Activation)
Kaynak dogrulama modu etkin.
Expert React development for modern, performant, and maintainable frontend applications.
Purpose
Provide comprehensive React expertise including React 18+ features (concurrent rendering, suspense, server components), performance optimization, state management patterns, and production-grade component architecture. Ensures React applications follow best practices and leverage the latest React capabilities.
When to Use This Skill
- Building React applications with modern patterns
- Optimizing React performance (re-renders, bundle size, lazy loading)
- Implementing complex state management (global state, server state)
- Creating reusable component libraries with TypeScript
- Migrating to React 18+ or Next.js App Router
- Setting up React testing with React Testing Library and Jest
- Implementing accessibility (a11y) in React components
Prerequisites
Required: JavaScript ES6+, TypeScript basics, HTML/CSS, npm/yarn/pnpm
Agent Assignments: coder (implementation), tester (React Testing Library), mobile-dev (React Native if needed)
Core Workflows
Workflow 1: Next.js 13+ App Router with Server Components
Step 1: Initialize Next.js Project
npx create-next-app@latest my-app --typescript --tailwind --app --no-src-dir
cd my-app
pnpm install
Step 2: Create Server Component (RSC)
// app/users/page.tsx (Server Component by default)
import { Suspense } from 'react';
import { UserList } from './user-list';
import { UserSkeleton } from './user-skeleton';
async function getUsers() {
const res = await fetch('https://api.example.com/users', {
next: { revalidate: 60 } // ISR: revalidate every 60s
});
return res.json();
}
export default async function UsersPage() {
const users = await getUsers();
return (
<main>
<h1>Users</h1>
<Suspense fallback={<UserSkeleton />}>
<UserList users={users} />
</Suspense>
</main>
);
}
Step 3: Create Client Component with Interactivity
// app/users/user-list.tsx
'use client'; // Marks as Client Component
import { useState } from 'react';
interface User {
id: number;
name: string;
email: string;
}
export function UserList({ users }: { users: User[] }) {
const [filter, setFilter] = useState('');
const filtered = users.filter(u =>
u.name.toLowerCase().includes(filter.toLowerCase())
);
return (
<div>
<input
type="text"
placeholder="Filter users..."
value={filter}
=> setFilter(e.target.value)}
className="border p-2 mb-4"
/>
<ul>
{filtered.map(user => (
<li key={user.id}>{user.name} ({user.email})</li>
))}
</ul>
</div>
);
}
Step 4: Implement Server Actions
// app/actions.ts
'use server';
import { revalidatePath } from 'next/cache';
export async function createUser(formData: FormData) {
const name = formData.get('name') as string;
const email = formData.get('email') as string;
await fetch('https://api.example.com/users', {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({ name, email }),
});
revalidatePath('/users'); // Revalidate users page
}
Workflow 2: State Management with Zustand
Step 1: Install Zustand
pnpm add zustand
Step 2: Create Type-Safe Store
// stores/user-store.ts
import { create } from 'zustand';
import { devtools, persist } from 'zustand/middleware';
interface User {
id: number;
name: string;
}
interface UserState {
users: User[];
addUser: (user: User) => void;
removeUser: (id: number) => void;
clearUsers: () => void;
}
export const useUserStore = create<UserState>()(
devtools(
persist(
(set) => ({
users: [],
addUser: (user) => set((state) => ({
users: [...state.users,
