shadcn/ui Components

Understanding shadcn/ui components helps you use UI libraries confidently. Here you will learn the core ideas behind shadcn/ui components, see working examples, and pick up best practices used on real teams.

shadcn/ui Components Overview

shadcn/ui Components lets you work with UI libraries in a way that stays clear, repeatable, and easy to scale. Instead of ad-hoc steps, you follow a pattern that other developers recognise immediately.

The key is to keep shadcn/ui components focused and predictable. Start from the minimal example here, then add only the complexity your situation actually needs.

// shadcn/ui copies components into your project so you own the code
import { Button } from '@/components/ui/button';

export function Example() {
  return <Button variant="default">Save</Button>;
}

shadcn/ui is not a dependency: you generate the component source into your own codebase.
