React Best Practices for 2025

As React continues to evolve, it's important to stay up-to-date with the latest best practices. Here's what you need to know for 2025.

1. Use React Server Components

Server Components are now a stable feature and should be your default choice for new applications:

// app/page.tsx
export default async function Page() {
  const data = await fetchData(); // This runs on the server
  return <div>{data.map(item => <Card key={item.id} {...item} />)}</div>;
}

2. Embrace the Use Hook Pattern

Hooks have evolved, and custom hooks are more powerful than ever:

function useUser(id: string) {
  const [user, setUser] = useState(null);
  
  useEffect(() => {
    fetchUser(id).then(setUser);
  }, [id]);
  
  return user;
}

3. Performance Optimization

Always consider performance implications:

const MemoizedComponent = memo(({ data }) => {
  return <div>{data.map(item => <Item key={item.id} {...item} />)}</div>;
});
