# 3. Button variants

이 문서는 다양한 버튼 스타일 및 변형을 쉽게 구현하기 위한 방법을 안내하는 가이드입니다.

***

### Button UI

Button은 variant가 많고, Tailwind CSS는 nested selector를 지양합니다.\
그러므로 React 컴포넌트로 구현하는 방식을 권장합니다.

### 설치

다음 패키지 3가지를 추가합니다. 가이드 2-3을 참조하여 `src/lib/utils.ts`를 설정하세요.

{% code title="설치 (pnpm)" %}

```bash
pnpm add tailwind-merge clsx class-variance-authority
```

{% endcode %}

### Button library 예시

아래는 예시로 구현한 Button 컴포넌트와 사용 예시입니다.

src/components/ui/button.tsx

{% code title="src/components/ui/button.tsx" %}

```typescript
import { VariantProps, cva } from 'class-variance-authority';
import { ComponentProps } from 'react';
import { cn } from '@/lib/utils';

const buttonVariants = cva(
  'inline-flex items-center justify-center rounded-md text-sm font-medium transition-colors focus:outline-none focus:ring-2 focus:ring-slate-400 focus:ring-offset-2 disabled:opacity-50 disabled:pointer-events-none data-[state=open]:bg-slate-100',
  {
    variants: {
      bgcolor: {
        default: 'bg-slate-900 text-slate-50 hover:bg-slate-700',
        pink: 'bg-pink-900 text-pink-50 hover:bg-pink-500',
      },
      outline: {
        default: 'border border-transparent',
        black: 'border-4 border-black',
      },
      size: {
        default: 'h-10 py-2 px-4 text-sm',
        sm: 'h-9 px-2 rounded-md text-xs',
        lg: 'h-11 px-8 rounded-md text-base',
      },
    },
    defaultVariants: {
      bgcolor: 'default',
      outline: 'default',
      size: 'default',
    },
  }
);

interface ButtonProps extends ComponentProps<'button'>, VariantProps<typeof buttonVariants> {}

const Button = ({ className, bgcolor, outline, size, ...props }: ButtonProps) => {
  return (
    <button
      className={cn(
        buttonVariants({
          bgcolor,
          outline,
          size,
          className,
        })
      )}
      {...props}
    />
  );
};

export default Button;
```

{% endcode %}

Component에서 Button 사용 예시 (page.tsx)

{% code title="사용 예시 — page.tsx" %}

```tsx
import Button from '@/components/ui/button';

const ButtonPage = () => {
  return (
    <>
      <Button>My Button 1</Button>
      <Button bgcolor="pink">My Button 2</Button>
      <Button bgcolor="pink" outline="black"> My Button 3 </Button>
      <Button bgcolor="pink" outline="black" size="lg"> My Button 4 </Button>
    </>
  );
};

export default ButtonPage;
```

{% endcode %}

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://tech.x2bee.com/dev-guide/pjt-prepare/publish-your-docs/store-front-framewok-next.js/03./3.-button-variants.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
