Installation

or

Usage

k object

The k object is a key part of Kuma UI's API. It provides pre-styled HTML elements that you can use as components in your application. These elements can be styled using utility props for inline styling. The utility props are type-safe and make it easy to write responsive styles.

import { k } from "@kuma-ui/core";

function App() {
  return (
    <k.div p={[4, 8]} m="2px" _hover={{ flexDir: "row" }}>
      hello world
    </k.div>
  );
}

css function

The css function is another way to style your components. It takes an object of styles and returns a string of hashed classNames that you can apply to your component using the className prop.

import { css } from "@kuma-ui/core";

const styles = css({ color: 'red', fontSize: '24px' });

function App() {
  return <div className={styles}>Hello, world!</div>;
}

Setup

Next.js

yarn add @kuma-ui/next-plugin

Pages Directory Version

next.config.js

const { withKumaUI } = require("@kuma-ui/next-plugin");

/** @type {import('next').NextConfig} */
const nextConfig = {
  reactStrictMode: true,
};

module.exports = withKumaUI(nextConfig);

App Router Version (Experimental)

next.config.js

const { withKumaUI } = require("@kuma-ui/next-plugin");

/** @type {import('next').NextConfig} */
const nextConfig = {
  reactStrictMode: true,
  experimental: {
    appDir: true
  }
};

module.exports = withKumaUI(nextConfig);

Please note that as of now, App Router is an experimental feature. A .kuma directory will be produced in the process, which should be added to your .gitignore file. If you delete the .kuma directory, make sure to also clear the .next cache.

Vite

yarn add @kuma-ui/vite

vite.config.ts

import { defineConfig } from "vite";
import react from "@vitejs/plugin-react";
import KumaUI from "@kuma-ui/vite";

// https://vitejs.dev/config/
export default defineConfig({
  plugins: [
    react({
      jsxRuntime: "classic",
    }),
    KumaUI(),
  ],
});

Responsive Design

Kuma UI supports responsive design. Use arrays to specify different styles for different viewport widths. For example, <k.div fontSize={[16, 24]} /> changes the font size from 16px to 24px based on the window size.

Define the breakpoints in your config file:

import kumaUI from "@kuma-ui/vite";

kumaUI({
  breakpoints: { sm: "400px", md: "700px" },
});
