Installation

Spark UI components are designed for React projects using Tailwind CSS v4 and TypeScript. Follow the steps below to get set up.

Prerequisites

Make sure your project has the following:

• React 19 or later
• Tailwind CSS v4
• TypeScript

Spark UI relies on the shared shadcn utilities (components.json, the cn() helper at @/lib/utils, and semantic design tokens). If you don't have shadcn set up yet, initialize it first:

npx shadcn@latest init

Most components also use a few shared utilities, installed automatically with each component or up front:

npm install framer-motion lucide-react clsx tailwind-merge

Add components

Option 1: Direct URL (recommended)

Pass the component's registry URL straight to the shadcn CLI — no configuration needed. For example, to add Shimmer Text:

Each component's docs page shows its exact install command.

Option 2: Registry namespace

Add the Spark UI registry to your components.json once:

{
  "registries": {
    "@spark-ui": "https://spark-ui-olive.vercel.app/r/{name}.json"
  }
}

Then install components by name:

npx shadcn@latest add @spark-ui/shimmer-text

Manual installation

If you prefer to install manually, copy the component source from its docs page (or from registry/spark-ui/ on GitHub) into your components directory, then install the dependencies that component's registry item declares — for example:

npm install framer-motion

The full dependency list for every component is in the registry index.

Project structure

After adding components, your project will look something like this:

components/
├── shimmer-text.tsx
├── tactile-highlight.tsx
└── ...
lib/
└── utils.ts
app/
└── api/spotify/metadata/route.ts   ← installed by spotify-card only

Components land in your configured components directory (see the aliases in your components.json). A few multi-file items install extra files — spotify-card adds its API route, which requires the Next.js App Router.

Usage

Import components from your local path — never from the registry:

import { ShimmerText } from "@/components/shimmer-text";

export function Announcement() {
  return <ShimmerText>Something special is coming.</ShimmerText>;
}

See individual component pages for detailed usage and examples.
