Use shadcn/ui or shadcn-vue or shadcn-svelte with UnoCSS

1. Based on fisand/unocss-preset-shadcn
2. Theme can be easily customized

Starter

You can easily start a new project without manually setting up the project.

• shadcn-vue-unocss-starter
• shadcn-svelte-unocss-starter

Usage

Follow the official guide to set up shadcn/ui, shadcn-vue, or shadcn-svelte. Replace the step to set up Tailwind CSS with UnoCSS.

Then install unocss-preset-shadcn and unocss-preset-animations, and update your unocss.config.ts:

ni -D unocss-preset-animations unocss-preset-shadcn

// unocss.config.ts
import { defineConfig, presetUno } from "unocss";
import presetAnimations from "unocss-preset-animations";
import { presetShadcn } from "unocss-preset-shadcn";

export default defineConfig({
  presets: [
    presetUno(),
    presetAnimations(),
    presetShadcn({
      color: "red",
    }),
  ],
  // By default, `.ts` and `.js` files are NOT extracted.
  // If you want to extract them, use the following configuration.
  // It's necessary to add the following configuration if you use shadcn-vue or shadcn-svelte.
  content: {
    pipeline: {
      include: [
        // the default
        /\.(vue|svelte|[jt]sx|mdx?|astro|elm|php|phtml|html)($|\?)/,
        // include js/ts files
        "src/**/*.{js,ts}",
      ],
    },
  },
});

[!IMPORTANT] Do not run npx shadcn-ui@latest init or npx shadcn-vue@latest init or npx shadcn-svelte@latest init to initialize your project.

1. ni lucide-react class-variance-authority clsx tailwind-merge
   • ni lucide-vue-next radix-vue class-variance-authority clsx tailwind-merge for shadcn-vue.
   • ni lucide-svelte tailwind-variants clsx tailwind-merge for shadcn-svelte.
2. copy utils.ts into your project at src/lib
3. create components.json in your project root and modify as needed
4. npx shadcn-ui@latest add button
   • npx shadcn-vue@latest add button for shadcn-vue.
   • npx shadcn-svelte@latest add button for shadcn-svelte.

[!WARNING] If you encounter problems adjusting animation property, this may be because tailwind-animate has duplicate rules about animation and transition. You can refer to Migration Guide from Animations Preset for UnoCSS to solve this problem.

Code to copy

import { clsx } from "clsx";
import { twMerge } from "tailwind-merge";

import type { ClassValue } from "clsx";

export function cn(...inputs: ClassValue[]) {
  return twMerge(clsx(inputs));
}

Dynamic Theme

Preview the demo.

If you want to use a dynamic theme, you can pass an array of theme objects to presetShadcn:

import { defineConfig, presetUno, UserConfig } from "unocss";
import presetAnimations from "unocss-preset-animations";
import { builtinColors, presetShadcn } from "unocss-preset-shadcn";

export default defineConfig({
  presets: [
    presetUno(),
    presetAnimations(),
    presetShadcn(builtinColors.map((c) => ({ color: c }))),
  ],
});

Add a theme sync script to your index.html. To dynamically change the theme, you can create a theme switch component.
