# UI Package

This package provides components that make up the UI.

## Installation

First, move to the page you want to use.

```shell
cd pages/options
```

Add the following to the dependencies in `package.json`.

```json
{
  "dependencies": {
    "@extension/ui": "workspace:*"
  }
}
```

Then, run `pnpm install`.

```shell
pnpm install
```

Add the following to the `tailwind.config.ts` file.

```ts
import baseConfig from '@extension/tailwindcss-config';
import { withUI } from '@extension/ui';

export default withUI({
  ...baseConfig,
  content: ['./index.html', './src/**/*.{js,ts,jsx,tsx}'],
});
```

Add the following to the `index.tsx` file.

```tsx
import '@extension/ui/dist/global.css';
```

## Add Component

Add the following to the `lib/components/index.ts` file.

```tsx
export * from './Button';
```

Add the following to the `lib/components/Button.tsx` file.

```tsx
import { ComponentPropsWithoutRef } from 'react';
import { cn } from '../utils';

export type ButtonProps = {
  theme?: 'light' | 'dark';
} & ComponentPropsWithoutRef<'button'>;

export function Button({ theme, className, children, ...props }: ButtonProps) {
  return (
    <button
      className={cn(
        className,
        'mt-4 py-1 px-4 rounded shadow hover:scale-105',
        theme === 'light' ? 'bg-white text-black' : 'bg-black text-white',
      )}
      {...props}>
      {children}
    </button>
  );
}
```

## Usage

```tsx
import { Button } from '@extension/ui';

export default function ToggleButton() {
  const [theme, setTheme] = useState<'light' | 'dark'>('light');

  const toggle = () => {
    setTheme(theme === 'light' ? 'dark' : 'light');
  };

  return (
    <Button theme={theme} onClick={toggle}>
      Toggle
    </Button>
  );
}
```

## Modifying the tailwind config of the UI library

Modify the `tailwind.config.ts` file to make global style changes to the package.

## Modifying the css variable of the UI library

Modify the css variable in the `ui/lib/global.css` code to change the css variable of the package.

## Guide for Adding shadcn to the UI Package

You can refer to the this [manual guide](https://ui.shadcn.com/docs/installation/manual)

1. Create components.json in packages/ui

Create a file named `components.json` in the `packages/ui` directory with the following content:

```json
{
  "$schema": "https://ui.shadcn.com/schema.json",
  "style": "default",
  "rsc": false,
  "tsx": true,
  "tailwind": {
    "config": "tailwind.config.ts",
    "css": "lib/global.css",
    "baseColor": "neutral",
    "cssVariables": true,
    "prefix": ""
  },
  "aliases": {
    "components": "@/lib/components",
    "utils": "@/lib/utils",
    "ui": "@/lib/components/ui",
    "lib": "@/lib"
  }
}
```

2. Install dependencies

Run the following command from the root of your project:

```shell
pnpm add tailwindcss-animate class-variance-authority -F ui
```

3. Edit `withUI.ts` in `lib` folder

This configuration file is from the manual guide. You can refer to the manual guide to modify the configuration file. ([`Configure tailwind.config.js`](https://ui.shadcn.com/docs/installation/manual))

```ts
import deepmerge from 'deepmerge';
import type { Config } from 'tailwindcss/types/config';
import { fontFamily } from 'tailwindcss/defaultTheme';
import tailwindAnimate from 'tailwindcss-animate';

export function withUI(tailwindConfig: Config): Config {
  return deepmerge(
    shadcnConfig,
    deepmerge(tailwindConfig, {
      content: ['./node_modules/@extension/ui/lib/**/*.{tsx,ts,js,jsx}'],
    }),
  );
}

const shadcnConfig = {
  darkMode: ['class'],
  theme: {
    container: {
      center: true,
      padding: '2rem',
      screens: {
        '2xl': '1400px',
      },
    },
    extend: {
      colors: {
        border: 'hsl(var(--border))',
        input: 'hsl(var(--input))',
        ring: 'hsl(var(--ring))',
        background: 'hsl(var(--background))',
        foreground: 'hsl(var(--foreground))',
        primary: {
          DEFAULT: 'hsl(var(--primary))',
          foreground: 'hsl(var(--primary-foreground))',
        },
        secondary: {
          DEFAULT: 'hsl(var(--secondary))',
          foreground: 'hsl(var(--secondary-foreground))',
        },
        destructive: {
          DEFAULT: 'hsl(var(--destructive))',
          foreground: 'hsl(var(--destructive-foreground))',
        },
        muted: {
          DEFAULT: 'hsl(var(--muted))',
          foreground: 'hsl(var(--muted-foreground))',
        },
        accent: {
          DEFAULT: 'hsl(var(--accent))',
          foreground: 'hsl(var(--accent-foreground))',
        },
        popover: {
          DEFAULT: 'hsl(var(--popover))',
          foreground: 'hsl(var(--popover-foreground))',
        },
        card: {
          DEFAULT: 'hsl(var(--card))',
          foreground: 'hsl(var(--card-foreground))',
        },
      },
      borderRadius: {
        lg: `var(--radius)`,
        md: `calc(var(--radius) - 2px)`,
        sm: 'calc(var(--radius) - 4px)',
      },
      fontFamily: {
        sans: ['var(--font-sans)', ...fontFamily.sans],
      },
      keyframes: {
        'accordion-down': {
          from: { height: '0' },
          to: { height: 'var(--radix-accordion-content-height)' },
        },
        'accordion-up': {
          from: { height: 'var(--radix-accordion-content-height)' },
          to: { height: '0' },
        },
      },
      animation: {
        'accordion-down': 'accordion-down 0.2s ease-out',
        'accordion-up': 'accordion-up 0.2s ease-out',
      },
    },
  },
  plugins: [tailwindAnimate],
};
```

4. Edit `global.css` in `lib` folder

        --accent-foreground: 210 40% 98%;

        --popover: 224 71% 4%;
        --popover-foreground: 215 20.2% 65.1%;

        --border: 216 34% 17%;
        --input: 216 34% 17%;

        --card: 224 71% 4%;
        --card-foreground: 213 31% 91%;

        --radius: 0.5rem;
    }
}

@layer base {
    * {
        @apply border-border;
    }
    body {
        @apply bg-background text-foreground;
        font-feature-settings: "rlig" 1, "calt" 1;
    }
}
```

5. Add shadcn components

Finally, run this command from the root of your project to add the button component:

```shell
pnpm dlx shadcn@latest add button -c ./packages/ui
```

This will add the shadcn button component to your UI package.

Remember to adjust any paths or package names if your project structure differs from the assumed layout in this guide. 

6. Export components

Make the `index.ts` file in the `components/ui` directory export the button component:

```ts
export * from './button';
```

Edit the `index.ts` file in the `packages/ui` directory to export the shadcn ui component:

```ts
// export * from './lib/components'; // remove this line: duplicated button component
export * from './lib/components/ui';
```
