### Create a derived Button component with icon and as prop support

Source: https://tw-classed.vercel.app/docs/derived-components

This example demonstrates creating a reusable `Button` component by wrapping a base `classed` button. It adds an optional `icon` prop and utilizes `deriveClassed` to correctly handle the `as` prop for rendering different HTML elements, ensuring refs are forwarded.

```typescript
import { classed, deriveClassed, ComponentProps } from"@tw-classed/react";

const ButtonBase = classed.button({
  base: "px-2 py-4 flex items-center gap-2",
  variants: {
    color: {
      blue: "bg-blue-500 text-white",
      red: "bg-red-500 text-white",
    },
  },
});

export type ButtonProps = ComponentProps<typeof ButtonBase> & {
  icon?: React.ReactNode; // Add an icon
};

export const Button = deriveClassed<typeof ButtonBase, ButtonProps>(
  ({ children, icon, ...rest }, ref) => {
    return (
      <ButtonBase {...rest} ref={ref}>
        {icon && <span>{icon}</span>}
        <span>{children}</span>
      </ButtonBase>
    );
  }
);

// Example Usage:
// import { CheckIcon, LinkIcon } from "example-icons";
// <Button color="blue">Click me</Button>
// <Button icon={<CheckIcon />}>Click me</Button>
// <Button as="a" href="/" icon={<LinkIcon />}>
//   Docs
// </Button>
```

--------------------------------

### React: Manual Strict Mode for Specific Variants

Source: https://tw-classed.vercel.app/docs/strict-components

Allows explicit designation of required variants. This example makes the 'loading' and 'size' variants mandatory for a Button component, while 'color' remains optional.

```javascript
import { makeStrict, classed } from"@tw-classed/react";

const Button = classed.button({
  base: "px-4 py-2 rounded-md",
  variants: {
    color: {
      primary: "bg-blue-500 text-white",
      secondary: "bg-gray-500 text-white",
    },
    size: {
      sm: "text-sm",
      lg: "text-lg",
    },
    loading: {
      true: "opacity-50 cursor-progress",
    },
  },
});

export default makeStrict(Button, "loading", "size");

// In your app:
// () => <Button />;
// // ❌ TypeError - "size" is required here
// // ❌ TypeError - "loading" is required here
```

--------------------------------

### React API: Data Attributes for Variants

const Button = classed("button", {
  variants: {
    color: {
      blue: "bg-blue-100",
      red: "bg-red-100",
    },
  },
  defaultVariants: {
    color: "red",
  },
  dataAttributes: ["color"],
});

<Button color="blue" />
// Rendered html will be
<button data-color="blue" />

<Button>
// Rendered html will be
<button data-color="red" /> // From default variants
```

const Button = classed.button("px-4 py-2", {
  variants: {
    color: {
      primary: "bg-blue-500 text-white",
      secondary: "bg-black text-white",
    },
  },
  defaultVariants: {
    color: "primary", // Default to primary
  },
});

);
```

--------------------------------

### TW CLASSED React Component Usage

Source: https://tw-classed.vercel.app/docs/faq

Illustrates how to use TW CLASSED within a React project. The `@tw-classed/react` package provides React components that integrate seamlessly with the library's features.

```JavaScript
import React from 'react';
import { classed } from "@tw-classed/react";

const StyledButton = classed('button', {
  variants: {
    intent: {
      primary: 'bg-blue-500 text-white hover:bg-blue-700',
      danger: 'bg-red-500 text-white hover:bg-red-700',
    },
    size: {
      medium: 'h-10 px-4',
      large: 'h-12 px-6',
    },
  },
  defaultVariants: {
    intent: 'primary',
    size: 'medium',
  },
});

function MyComponent() {

    <>
      <StyledButton intent="primary" size="large">Large Primary Button</StyledButton>
      <StyledButton intent="danger">Danger Button</StyledButton>
    </>
  );
}

export default MyComponent;
```

--------------------------------

### React: Automatic Strict Mode with Default Variants

Source: https://tw-classed.vercel.app/docs/strict-components

Enforces required variants based on defaultVariants. If a variant lacks a default, it becomes mandatory. This example shows a Button component where 'size' is required because it has no default, while 'color' is optional due to its default value.

```javascript
import { makeStrict, classed } from"@tw-classed/react";

const Button = classed.button({
  base: "px-4 py-2 rounded-md",
  variants: {
    color: {
      primary: "bg-blue-500 text-white",
      secondary: "bg-gray-500 text-white",
    },
    size: {
      sm: "text-sm",
      lg: "text-lg",
    },
  },
  defaultVariants: {
    color: "primary",
  },
});

export default makeStrict(Button);

// In your app:
// () => <Button />; // ❌ TypeError - size is required here
```

--------------------------------

### Configure Variants for Data Attribute Serialization

Source: https://tw-classed.vercel.app/docs/data-variants

This example demonstrates how to configure the `color` variant to be serialized as a data attribute. By adding `dataAttributes: ["color"]` to the variant configuration, the `color` prop will be rendered as a `data-color` attribute on the HTML element.

```javascript
const Button = classed.button("p-4 group", {
  variants: {
    color: {
      light: "bg-white text-slate-900",
      dark: "bg-slate-900 text-white",
    },
    dataAttributes: ["color"],
  },
});
```

--------------------------------

### Add Variants to Grid Component

Source: https://tw-classed.vercel.app/docs/guide/writing-clean-classed

```javascript
constGrid=classed.div(
"grid gap-4",// Mobile first
"md:grid-cols-2 md:gap-6",// Tablet
"lg:grid-cols-3 lg:gap-8",// Desktop
"xl:grid-cols-4",// Large desktop
  {
    variants: {
      columns: {
1:"!grid-cols-1",// Notice the cheeky ! to override the current grid-cols
2:"!grid-cols-2",
3:"!grid-cols-3",
4:"!grid-cols-4",
      },
    },
  }
);
() => (
  <Gridcolumns={2}>
    <div>1</div>
    <div>2</div>
  </Grid>
); // Regardless of screen size, this will always have 2 columns
```

import { getVariantConfig } from "@tw-classed/react";

const Button = classed("button", {
  variants: {
    color: {
      blue: "bg-blue-500",
    },
  },
});

const { variants } = getVariantConfig(Button);
console.log(variants.color.blue); // "bg-blue-500"
```

--------------------------------

### TypeScript: TW-Classed Variants and Prop Inference

  size?: 'small' | 'large';
}

const Button = classed<ButtonProps>('button', {
  variants: {
    color: {
      primary: 'bg-blue-500 text-white',
      secondary: 'bg-gray-200 text-gray-800',
    },
    size: {
      small: 'py-1 px-2',
      large: 'py-2 px-4',
    },
  },
  defaultVariants: {
    color: 'primary',
    size: 'small',
  },
});

// Usage with TypeScript:

```

--------------------------------

### Nested Components Reacting to Parent Variants via Data Attributes

Source: https://tw-classed.vercel.app/docs/data-variants

This example illustrates how nested components can react to parent component variants using data attributes. The `LoadingSpinner` component's styling is conditionally applied based on the parent `Button`'s `color` variant using `group-data-[color=dark]:text-white`.

```javascript
const Button = classed.button("p-4 group", {
  variants: {
    color: {
      light: "bg-white text-slate-900",
      dark: "bg-slate-900 text-white",
    },
    dataAttributes: ["color"],
  },
});

const LoadingSpinner = classed(
  FiSpinner,
  "animate-spin rounded-full h-8 w-8 text-slate-900",
  "group-data-[color=dark]:text-white" // Matches when button is dark variant
);

() => {

### Create Button with CSS Modules and tw-classed

Source: https://tw-classed.vercel.app/docs/guide/with-css-modules

Defines a Button component using tw-classed and SCSS Modules. It includes variants for color (primary, secondary, danger) and sets default variants. Assumes TypeScript knowledge.

```SCSS
// Button.module.scss
.button {
  display:flex;
  align-items:center;
  justify-content:center;
  padding:0.5rem 1rem;
  border-radius:0.25rem;
  border:1px solid transparent;
  font-size:1rem;
  font-weight:500;
  &.primary {
    background-color:#3182ce;
    color:#fff;
    border-color:#2b6cb0;
  }
  &.secondary {
    background-color:#cbd5e0;
    color:#2d3748;
    border-color:#a0aec0;
  }
  &.danger {
    background-color:#e53e3e;
    color:#fff;
    border-color:#c53030;
  }
}
```

```TypeScript
import classes from"./Button.module.scss";
import { classed } from"@tw-classed/react";

const Button = classed("button", classes.button, {
  variants: {
    color: {
      primary: classes.primary,
      secondary: classes.secondary,
      danger: classes.danger,
    },
  },
  defaultVariants: {
    color: "primary",
  },
});

export type ButtonProps = React.ComponentProps<typeof Button>;
```

```React
<Button color="primary">Primary</Button>
<Button color="secondary">Secondary</Button>
<Button color="danger">Danger</Button>
```

Demonstrates how to use the 'class' and 'className' props with a class producer function in the core library. This allows for dynamic class application.

```javascript
const button = classed("bg-blue-500");
// LitHTML
html`<button class=${button({ class: "text-white" })}>Click me</button>`;
```

--------------------------------

### Organize Button Classes with Multiple Arguments (React)

Source: https://tw-classed.vercel.app/docs/guide/writing-clean-classed

Illustrates a method for organizing class strings in `tw-classed` by using multiple arguments. This approach separates default styles, responsive adjustments, and interactive states (hover, focus) for better readability and maintainability.

```TypeScript
const CardButton = classed.a(
  "p-4 w-[200px] text-center text-white bg-blue-500 rounded-md", // Defaults
  "md:p-6 lg:p-8 md:w-[300px] lg:w-[400px]", // Media queries
  "hover:bg-blue-600 focus:bg-blue-700" // Hover & focus
);
```

--------------------------------

### Create Derived Components with DerivedComponentType

Source: https://tw-classed.vercel.app/docs/typescript

Illustrates how to create a derived component by extending a base classed component, overriding its type with `DerivedComponentType` for correct TypeScript `as` prop handling.

```TypeScript
import { DerivedComponentType } from"@tw-classed/react";
import { forwardRef } from"react";
import { classed } from"@tw-classed/react";
constBaseButton=classed("button","px-2 py-4", {
  variants: {
    color: {
      blue:"bg-blue-500",
      red:"bg-red-500",
    },
  },
});
typeBaseButtonProps=React.ComponentProps<typeof BaseButton> & {
  icon?:React.ReactNode; // Add an icon prop
};
constButton=forwardRef<HTMLButtonElement,BaseButtonProps>(
  ({ icon,...props }, ref) => {
return (
      <BaseButton {...props} ref={ref}>
        {icon && <spanclassName="mr-2">{icon}</span>}
        {props.children}
      </BaseButton>
    );
  }
) asDerivedComponentType<typeof BaseButton,BaseButtonProps>;
() => (
  <Buttoncolor="blue"as="a"href="/">
    Click me
  </Button>
);
```

--------------------------------

### Create Button Component with Variants and Compound Variants

Source: https://tw-classed.vercel.app/docs/changelog

Demonstrates how to create a reusable Button component using `classed.button`. It defines base styles, size and color variants, and a compound variant that applies a special class when specific size and color combinations are met. It also shows how to create a new component `GreenButton` that inherits from `Button` and sets a default variant.

```javascript
const Button = classed.button({
  base: "bg-blue-500 text-white",
  variants: {
    size: {
      sm: "px-2 py-1 text-sm",
      md: "px-4 py-2 text-base",
    },
    color: {
      red: "bg-red-500",
      green: "bg-green-500",
    },
  },
  compoundVariants: [
    {
      size: "sm",
      color: "green",
      class: "super-special-class-modifyer"
    },
  ],
});

const GreenButton = classed(Button, {
  defaultVariants: {
    color: "green", // This now triggers the compoundVariant
  },
});
```

--------------------------------

### Create Classed with Tailwind Merge (React)

Source: https://tw-classed.vercel.app/docs/guide/configuring-classed

Shows how to integrate 'classed' with the 'tailwind-merge' library to enable intelligent merging of Tailwind CSS classes. This is useful for managing class overrides, especially with variants.

```TypeScript
// classed.config.ts
import { twMerge } from"tailwind-merge";
import { createClassed } from"@tw-classed/react";
exportconst { classed } =createClassed({ merger: twMerge });
```

--------------------------------

### TypeScript Configuration Compatibility

Source: https://tw-classed.vercel.app/docs/changelog

Ensures compatibility with `exactOptionalPropertyTypes: true` in TypeScript configurations. This fix addresses potential type-checking issues for projects with strict TypeScript settings.

```typescript
// This change ensures that the library's types are compatible with
// TypeScript projects that have exactOptionalPropertyTypes enabled.
// No direct code snippet is shown as it's a type-level compatibility fix.
```

--------------------------------

### TypeScript Interoperability: Core and React

Source: https://tw-classed.vercel.app/docs/changelog

Shows how to achieve TypeScript interoperability between @tw-classed/core and @tw-classed/react. This enables using a framework-agnostic design system with React applications.

```typescript
// Design system
import { classed } from "@tw-classed/core";
export const button = classed({
  base: "bg-blue-500 text-white",
  variants: {
    size: {
      sm: "px-2 py-1 text-sm",
      md: "px-3 py-2 text-base",
      lg: "px-4 py-3 text-lg",
    },
  },
});
// React application
import { button } from "design-system";
import { classed } from "@tw-classed/react";
export const Button = classed.button(button); // Variants are automatically inferred
```

--------------------------------

### Utilize Proxy API for classed

Source: https://tw-classed.vercel.app/docs/changelog

Adds support for the Proxy API, allowing `classed.button(...args)` syntax. The existing `classed` API remains unchanged and utilizes the proxy internally. This enables more flexible component styling.

```JavaScript
import { classed } from "@tw-classed/core";

// Using the new Proxy API
const Button = classed.button('px-4 py-2 rounded', {
  variants: {
    color: {
      primary: 'bg-blue-500 text-white',
      secondary: 'bg-gray-200 text-black'
    }
  }
});

// Regular classed API usage remains the same
const Card = classed('div', {
  base: 'p-4 border rounded',
  variants: {
    shadow: {
      true: 'shadow-md'
    }
  }
});
```

--------------------------------

### Render Grid Component within Classed Function

Source: https://tw-classed.vercel.app/docs/guide/writing-clean-classed

Illustrates how to render a Grid component directly within a classed function definition. This approach allows the Grid component's classes and variants to be applied, and the component itself to be rendered, by placing it at the beginning of the classed function arguments.

```javascript
constCardGrid=classed(
  Grid,// Render the Grid component
"p-4 rounded-md",
  {
    variants: {
      color: {
        gray:"bg-gray-500",
        blue:"bg-blue-500",
        red:"bg-red-500",
      },
    },
  },
);
() => (
  <CardGridcolumns={2} color="red">
    <div>1</div>
    <div>2</div>
  </CardGrid>
);
```

--------------------------------

### createClassed API: Extending Functionality

Source: https://tw-classed.vercel.app/docs/changelog

Introduces the createClassed API, which allows extending the 'classed' function with additional capabilities. Currently, it supports the 'merger' prop.

```javascript
// Example usage of createClassed API would go here, but is not provided in the input.
```

--------------------------------

### Remap Button styles to an 'a' element with tw-classed

Source: https://tw-classed.vercel.app/docs/guide/with-css-modules

Shows how to create a new component (Link) that inherits the styles of the Button component but renders as an 'a' element using tw-classed. This promotes style reuse and flexibility.

```TypeScript
// Link.tsx
// ...
import { Button } from"./Button";

export const Link = classed("a", Button);
```

```React
<Link href="/home" color="primary">
  Primary
</Link>
```

--------------------------------

### Core: Support deriveClassed and makeStrict

Source: https://tw-classed.vercel.app/docs/changelog

Adds support for two new functionalities: `deriveClassed` and `makeStrict`. This update also includes internal core typing updates to ensure compatibility with these new features.

```javascript
// Adds support for `deriveClassed` & `makeStrict`.
// Updated core internal typing for compatibility.
```

--------------------------------

### Extend Progress Component with Variants

Source: https://tw-classed.vercel.app/docs/guide/using-radix-ui

Enhances the classed progress bar by adding variants for the indicator color, controlled by tw-classed.

```jsx
// Progress.jsx
// ...
constClassedIndicator=classed(
ProgressPrimitive.Indicator,
classes.indicator,
  {
    variants: {
      color: {
        blue:"!bg-blue-500",
        purple:"!bg-purple-500",
      },
    },
    defaultVariants: {
      color:"blue",
    },
  }
);
// exports
exportconstProgress= ({ value =0, color }) => (
  <ClassedRootvalue={value}>
    <ClassedIndicator
color={color}
style={{
        transform:`translateX(-${100- value})`,
      }}
    />
  </ClassedRoot>
);
```

--------------------------------

### Add Configurable Color Variants to CardGrid

Source: https://tw-classed.vercel.app/docs/guide/writing-clean-classed

Extends the CardGrid component to include configurable color variants. This allows developers to easily change the background color of the grid by passing a color prop, such as 'red', 'blue', or 'gray'.

```javascript
constCardGrid=classed.div(
"p-4 rounded-md",
  Grid,// Inherit the Grid's classes and variants
  {
    variants: {
      color: {
        gray:"bg-gray-500"
        blue: "bg-blue-500",
        red:"bg-red-500",
      },
    },
  }
);
() => (
  <CardGridcolumns={2} color="red">
    <div>1</div>
    <div>2</div>
  </CardGrid>
);
```

--------------------------------

### Rendered Button without Tailwind Merge (React)

Source: https://tw-classed.vercel.app/docs/guide/configuring-classed

Shows the potential HTML output for a 'Button' component without 'tailwind-merge', where class order might lead to unexpected style application or duplication.

```HTML
<button
class="bg-blue-500 text-white py-2 px-4 text-lg py-3 px-5 rounded-md"
></button>
```

--------------------------------

### Retrieve Variant Configuration from a Component

Source: https://tw-classed.vercel.app/docs/api

Illustrates how to use the `getVariantConfig` function to extract the variant configuration from a component previously created with `classed`. This allows programmatic access to variant definitions.

```javascript
const Button = classed("button", {
  variants: {
    color: {
      blue: "bg-blue-500",
    },
  },
});

const { variants } = getVariantConfig(Button);
variants.color.blue; // "bg-blue-500"
```

--------------------------------

### Experimental: Manually support 'as' prop with deriveClassed

Source: https://tw-classed.vercel.app/docs/derived-components

This snippet shows an experimental feature of `deriveClassed` that allows manual control over the `as` prop within the render function. It requires specifying the `as` prop type as a generic argument to `deriveClassed` for correct type inference.

```typescript
import { classed, deriveClassed, ComponentProps } from "@tw-classed/react";

// Assuming ButtonBase is defined as in the previous example
// const ButtonBase = classed.button({...});
// export type ButtonProps = ComponentProps<typeof ButtonBase> & { icon?: React.ReactNode };

export const Anchor = deriveClassed<typeof ButtonBase, ButtonProps, "a">(
  ({ children, icon, ...rest }, ref) => {
    return (
      <ButtonBase as="a" {...rest} ref={ref}>
        {icon && <span>{icon}</span>}
        <span>{children}</span>
      </ButtonBase>
    );
  }
);

// Usage:
// <Anchor href="/" icon={<LinkIcon />}>
//   Go to Home
// </Anchor>
```

--------------------------------

### Create Compound Variants

Source: https://tw-classed.vercel.app/docs/variants

Demonstrates how to define compound variants, which apply styles based on combinations of other variants. This is achieved using an array of variant conditions and associated class names.

```javascript
constButton=classed("button", {
  variants: {
    color: {
      primary:"text-white bg-blue-500",
      secondary:"text-white bg-gray-700",
    },
    size: {
      small:"py-2 px-4",
      medium:"py-3 px-6",
      large:"py-4 px-8",
    },
  },
  compoundVariants: [
    {
      size:"small",
      color:"primary",
      class:"rounded",// Classes when both size and color are small and primary will be applied
      className:"",// This is also supported if you prefer to use className
    },
  ],
});
() => (
  <Buttoncolor="primary"size="medium">
    Button
  </Button>
);
```

--------------------------------

### Support compoundVariants and base property

Source: https://tw-classed.vercel.app/docs/changelog

Enhances the configuration object with full support for `compoundVariants` and the `base` property. This allows for more complex styling rules and defining default styles.

```JavaScript
import { classed } from "@tw-classed/core";

const Alert = classed('div', {
  base: 'p-4 rounded',
  variants: {
    status: {
      info: 'bg-blue-100 text-blue-800',
      warning: 'bg-yellow-100 text-yellow-800'
    },
    variant: {
      solid: 'font-bold',
      outline: 'border-2'
    }
  },
  compoundVariants: [
    {
      status: 'info',
      variant: 'outline',
      class: 'border-blue-300'
    },
    {
      status: 'warning',
      variant: 'solid',
      class: 'bg-yellow-500 text-white'
    }
  ]
});
```

--------------------------------

### Create Classed with Custom Merger (React)

Source: https://tw-classed.vercel.app/docs/guide/configuring-classed

Demonstrates how to create a custom merger function for 'classed' that removes duplicate class names using a JavaScript Set. This configuration is applied via the `createClassed` method.

```TypeScript
// classed.config.ts
import { createClassed } from"@tw-classed/react";
// custom merger that removes duplicates using Set
const customMerger= (...classes:string[]) =>
Array.from(newSet(classes)).join(" ");
exportconst { classed } =createClassed({ merger: customMerger });
```

--------------------------------

### Remap Button element using 'as' prop with tw-classed

Source: https://tw-classed.vercel.app/docs/guide/with-css-modules

Illustrates using the 'as' prop with tw-classed to dynamically change the rendered element of a component (e.g., Button) to an 'a' tag while retaining its styles and props.

```React
import { Button } from"./Button";

() => (
  <Button as="a" href="/home" color="primary">
    Primary
  </Button>
);
```

--------------------------------

### Compose BaseButton with Variants and DefaultVariants

Source: https://tw-classed.vercel.app/docs/composing-components

Demonstrates composing a `BaseButton` component into a `CheckoutButton`. The `CheckoutButton` inherits all properties from `BaseButton` and adds its own styling, variants for size, and default variants for disabled state.

```javascript
import { classed } from"@tw-classed/react";
const BaseButton=classed("button");
const CheckoutButton=classed(
  BaseButton,
  "bg-blue-500 text-white font-bold py-2 px-4 rounded",
  {
    variants: {
      size: {
        sm:"text-sm",
        lg:"text-lg",
      },
    },
    defaultVariants: {
      disabled:"opacity-50 cursor-not-allowed",
    },
  }
);

() => (
  <>
    <BaseButton>Base Button</BaseButton>
    <CheckoutButtonsize="sm">Checkout Button</CheckoutButton>
  </>
);
```
