# dripsy-variants

**Variant utility for Dripsy** – A lightweight helper to build style variants and compound variants using `sx` props.

> Inspired by Tailwind Variants and styled-system patterns.

## ✨ Features

- ✅ Define `base` styles
- ✅ Support for multiple `variants`
- ✅ Support for `compoundVariants`
- ✅ `defaultVariants` handling
- ✅ Type-safe with full TypeScript support

## 📦 Installation

```bash
npm install dripsy-variants
# or
yarn add dripsy-variants
```

> Make sure you also have `dripsy` installed.

## 🚀 Usage

```typescript
import { createDripsyVariant } from "dripsy-variants";

const getButtonStyles = createDripsyVariant({
  base: {
    flexDirection: "row",
    alignItems: "center",
    gap: 10,
  },

    variant: {
      primary: { backgroundColor: "#0F0F0F" },
      secondary: { backgroundColor: "#E8E8E8" },
      link: { backgroundColor: "transparent" },
    },
    size: {
      md: { py: "$1_5", px: "$2", borderRadius: 16 },
      sm: { py: "$1", px: "$2", borderRadius: 12 },
    },

export const Button = ({

    >
      {({ pressed }) => {

        const colorToken = textStyles.color as keyof typeof theme.colors;

        const renderedIcon = enhanceIconElement(icon, {
          color: resolvedColor,

        return (

            <Text sx={textStyles}>{title}</Text>
            <View sx={{ width: 20 }}>{icon && renderedIcon}</View>

## 🧠 API Reference

### `createDripsyVariant(config)`

#### `config.base?: SxProp`

Base styles applied to all variants.

#### `config.variants?: Record<string, Record<string, SxProp>>`

Object containing named variants (like `variant`, `size`, etc.).

#### `config.defaultVariants?: { [K in keyof Variants]?: keyof Variants[K] }`

Default values used when no variant prop is passed.

#### `config.compoundVariants?: CompoundVariant[]`

List of compound variant conditions to apply extra styles based on a combination of variant values.

Each `CompoundVariant` is:

{
sx: SxProp;
[key: string]: string[]; // matches variant keys and values
}
