tailwindcss-shadcn-ui

A plugin/preset for Tailwind CSS v3.2+ that provides base utilities for shadcn ui.

Installation

This plugin requires tailwindcss and tailwindcss-animate

npm

npm install tailwindcss-shadcn-ui --save-dev

yarn

yarn install -D tailwindcss-shadcn-ui

pnpm

pnpm add -D tailwindcss-shadcn-ui

Configuration

Recommend

Add the shadcn preset to your tailwind config file unsing the preset creator function.

With this approach we can get a full configured preset including tailwindcss-animate plugin and dark mode set to class. Shoutout to @simonswiss. He metioned the preset way in his video.

// tailwind.config.ts
import { type Config } from "tailwindcss";
import { createPreset } from "tailwindcss-shadcn-ui";

export default {
    presets: [createPreset()],
    // ...
} satisfies Config;

Alternative

With this approach we can not preconfigure the plugins to include the tailwindcss-animate plugin. So you have to include it yourself.

// tailwind.config.ts
import { type Config } from "tailwindcss";
import tailwindAnimate from "tailwindcss-animate";
import tailwindShadcnUi from "tailwindcss-shadcn-ui";

export default {
    darkMode: ["class"],
    // ...
    plugins: [
        // ...
        tailwindShadcnUi,
        tailwindAnimate,
    ],
} satisfies Config;

Theme presets

// tailwind.config.ts
import { createPreset } from "tailwindcss-shadcn-ui";
import { DEFAULT } from "tailwindcss-shadcn-ui/themes";

export default {
    presets: [createPreset({ theme: DEFAULT })],
    // ..
};

// tailwind.config.ts
import tailwindShadcnUi from "tailwindcss-shadcn-ui";
import { DEFAULT } from "tailwindcss-shadcn-ui/themes";

export default {
    // ...
    plugins: [
        // ...
        tailwindShadcnUi({
            theme: DEFAULT,
        }),
    ],
};

Available presets

| Preset | Files | | ------- | -------------------------------------------- | | DEFAULT | themes/default.ts |

Define your own theme

// tailwind.config.ts

import { createPreset, defineTheme } from "tailwindcss-shadcn-ui";
import { DEFAULT } from "tailwindcss-shadcn-ui/themes";

export default {
    presets: [
        createPreset({
            theme: defineTheme({
                base: {
                    radius: "2rem", // string|number(pixels),
                    fontFamily: "Inter", // string|string[]
                },
                light: {
                    background: "0 0% 0%", // `${number} ${number}% ${number}%`
                    foreground: [0, 0, 0], // [hue: number, saturation: number, lightness: number]
                    //...
                },
                dark: {
                    background: "#000000", // `#${string}`
                    // ...
                },
            }),
        }),
    ],
    // ..
};

export default {
    // ...
    plugins: [
        // ...
        tailwindShadcnUi({
            theme: defineTheme({
                // ..
            }),
        }),
    ],
};
