const Tabs = ({ children }) => {
const [active, setActive] = useState(0);
return (
<TabsContext.Provider value={{ active, setActive }}>
{children}
</TabsContext.Provider>
);
};
Tabs.List = TabList;
Tabs.Panel = TabPanel;
function useDebounce<T>(value: T, delay = 500): T {
const [debouncedValue, setDebouncedValue] = useState(value);
useEffect(() => {
const timer = setTimeout(() => setDebouncedValue(value), delay);
return () => clearTimeout(timer);
}, [value, delay]);
return debouncedValue;
}
Use Server Components by default. Add 'use client' only when you need:
import Image from 'next/image';
// Above the fold - load immediately
<Image
src="/hero.jpg"
alt="Hero"
width={1200}
height={600}
priority
/>
// Responsive image with fill
<div className="relative aspect-video">
<Image
src="/product.jpg"
alt="Product"
fill
sizes="(max-width: 768px) 100vw, 50vw"
className="object-cover"
/>
</div>
<button>, <nav>, <main>)// Accessible button
<button
type="button"
aria-label="Close dialog"
onClick={onClose}
className="focus-visible:ring-2 focus-visible:ring-blue-500"
>
<XIcon aria-hidden="true" />
</button>
import { cn } from '@/lib/utils';
<button className={cn(
'px-4 py-2 rounded',
variant === 'primary' && 'bg-blue-500 text-white',
disabled && 'opacity-50 cursor-not-allowed'
)} />
// Props with children
interface CardProps {
className?: string;
children: React.ReactNode;
}
// Generic component
interface ListProps<T> {
items: T[];
renderItem: (item: T) => React.ReactNode;
}
function List<T>({ items, renderItem }: ListProps<T>) {
return <ul>{items.map(renderItem)}</ul>;
}
