@tw-classed/react

tw-classed

A Stitches & Styled-Components inspired library to create reusable Tailwind based components, fully typed with polymorphic as prop, media queries and interaction support.

See the documentation for more information.

Installation

npm i @tw-classed/react

Usage

// With `tw-classed`
import { classed } from "@tw-classed/react";
const Button = classed("button", "bg-blue-500 text-white p-4 rounded-md");

// Without `tw-classed`
import { forwardRef } from "react";
type ButtonProps = React.ButtonHTMLAttributes<HTMLButtonElement>;

const Button = forwardRef<HTMLButtonElement, ButtonProps>(
  ({ className, children, ...props }, ref) => (
    <button
      className="bg-blue-500 text-white p-4 rounded-md"
      ref={ref}
      {...props}
    >
      {children}
    </button>
  )
);

Multiple argument support

// Grid.tsx
import { classed } from "@tw-classed/react";

const Grid = classed(
  "div",
  "grid-cols-1 gap-4",
  "md:grid-cols-2",
  "lg:grid-cols-3",
  "xl:grid-cols-4"
);

export default Grid;

Using Variants

Insert an object as an argument to classed to define variants and defaultVariants for the component. Later use the key i.e color prop to set the variant.

// Button.tsx
import { classed } from "@tw-classed/react";

const Button = classed("button", "p-4 rounded-md", {
  variants: {
    color: {
      blue: "bg-blue-500 text-white",
      primary: "bg-indigo-500 text-white",
    },
  },
  defaultVariants: {
    color: "blue",
  },
});

const MyApp = () => {
  return (
    <>
      <Button color="primary">Im the primary color</Button>
      <Button color="blue">Im the blue color</Button>
      <Button>Im the default color (blue)</Button>
    </>
  );
};

Using the as prop

This allows for TypeScript intellisense to infer props based on the as prop.

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

const Button = classed("button", "bg-blue-500 text-white p-4 rounded-md");

const MyApp = () => {
  return (
    <Button as="a" href="https://example.com" target="_blank">
      click me
    </Button>
  );
};
