⚠️ BETA SOFTWARE: This library is in active development and not yet recommended for production use. APIs may change without notice. Feel free to try it out and provide feedback!
Provides a way to styling components in React Native with better experience and composability. The key feature is the ability to create multi-variants styles with a type-safe definition inspired by Stitches and CVA (for React apps).
base
: The base styles for the element.variants
: The different visual styles for the element.compoundVariants
: Styles that apply when multiple other variant conditions are met.defaultVariants
: Set a variant by default when no variant is provided.
- Variants definition.
- Default variants.
- Support to define design tokens.
- Default design tokens.
To configure Jacaranda
, create a jacaranda.config.ts
file (.js
works too) to define your reusable design tokens and import the defineTokens
function.
// jacaranda.config.ts import { defineTokens } from 'jacaranda';
This function receives an object with the design tokens.
colors
: Define your colors design tokens.space
: Define your spacing.fonts
: Define your fonts.fontSize
: Define your font sizes.lineHeight
: Define your line heights.
And returns a sva
function that you can use to style your components.
// jacaranda.config.ts import { defineTokens } from 'jacaranda'; export const { sva, tokens } = defineTokens({ colors: { primary50: '#ecfeff', primary100: '#cffafe', primary200: '#a5f3fc', primary300: '#67e8f9', primary400: '#22d3ee', primary500: '#06b6d4', primary600: '#0e93d1', primary700: '#1570ad', secondary50: '#ecfdf5', secondary100: '#d9f9eb', secondary200: '#bbfde8', secondary300: '#86f9d9', secondary400: '#0d9488', secondary500: '#027a7b', secondary600: '#016464', secondary700: '#014747', }, fontSize: { xs: 4, sm: 8, md: 16, lg: 24, xl: 32, xxl: 40, }, });
After the tokens are defined, you can use the design tokens in your components. You'll be importing the sva
function from the jacaranda.config.ts
file.
// Button.tsx import { TouchableOpacity } from 'react-native'; import { type VariantProps } from 'jacaranda'; import { sva } from './jacaranda.config'; type ButtonProps = VariantProps<typeof buttonStyles> & { children?: React.ReactNode; }; export const Button = (props: ButtonProps) => { return ( <TouchableOpacity style={buttonStyles(props)}> <Text>Click me</Text> </TouchableOpacity> ); }; const buttonStyles = sva({ base: { borderRadius: 8, }, variants: { intent: { primary: { backgroundColor: '$colors.primary50', }, secondary: { backgroundColor: '$colors.secondary50', }, }, size: { sm: { paddingHorizontal: 8, paddingVertical: 6 }, md: { paddingHorizontal: 12, paddingVertical: 8 }, lg: { paddingHorizontal: 16, paddingVertical: 10 }, }, }, defaultVariants: { intent: 'primary', size: 'md', }, });
You can use the VariantProps
type to extract the variants from a component.
import { type VariantProps } from 'jacaranda'; type ButtonProps = VariantProps<typeof buttonStyles>;
