Composing Components
Whilst cva doesn't yet offer a built-in method for composing components, it does offer the tools to extend components on your own terms…
For example; two cva components, concatenated together with cx:
// components/card.ts
import type { VariantProps } from "class-variance-authority";
import { cva, cx } from "class-variance-authority";
/**
* Box
*/
export type BoxProps = VariantProps<typeof box>;
export const box = cva(["box", "box-border"], {
variants: {
margin: { 0: "m-0", 2: "m-2", 4: "m-4", 8: "m-8" },
padding: { 0: "p-0", 2: "p-2", 4: "p-4", 8: "p-8" },
},
defaultVariants: {
margin: 0,
padding: 0,
},
});
/**
* Card
*/
type CardBaseProps = VariantProps<typeof cardBase>;
const cardBase = cva(["card", "border-solid", "border-slate-300", "rounded"], {
variants: {
shadow: {
md: "drop-shadow-md",
lg: "drop-shadow-lg",
xl: "drop-shadow-xl",
},
},
});
export interface CardProps extends BoxProps, CardBaseProps {}
export const card = ({ margin, padding, shadow }: CardProps = {}) =>
cx(box({ margin, padding }), cardBase({ shadow }));
