- Node.js 18+ with bun, npm, or pnpm

## Installation

### Initial Setup

**For New Projects:**

```bash
# Create Next.js project (bun preferred)
bunx create-next-app@latest my-app
# or: npx create-next-app@latest my-app
# or: pnpm create next-app@latest my-app

cd my-app

# Select these options:
# - TypeScript: Yes
# - ESLint: Yes
# - Tailwind CSS: Yes
# - src/ directory: Optional
# - App Router: Yes (recommended)
# - Import alias: @/* (default)
```

**Initialize Aceternity UI via shadcn CLI:**

```bash
# Using bun (preferred)
bunx --bun shadcn@latest init

# Using npm
npx shadcn@latest init

# Using pnpm
pnpm dlx shadcn@latest init

# During setup:
# - Style: New York (recommended)
# - Color: Zinc (or your preference)
# - CSS variables: Yes (recommended)
```

**Configure Registry:**

After initialization, update `components.json` to add Aceternity registry:

```json
{
  "$schema": "https://ui.shadcn.com/schema.json",
  "style": "new-york",
  "rsc": true,
  "tsx": true,
  "tailwind": {
    "config": "tailwind.config.ts",
    "css": "app/globals.css",
    "baseColor": "zinc",
    "cssVariables": true
  },
  "aliases": {
    "components": "@/components",
    "utils": "@/lib/utils"
  },
  "registries": {
    "@aceternity": "https://ui.aceternity.com/registry/{name}.json"
  }
}
```

### Installing Components

**Using shadcn CLI 3.0+ (Namespaced Registry):**

```bash
# Install specific component
bunx shadcn@latest add @aceternity/background-beams
# or: npx shadcn@latest add @aceternity/background-beams
# or: pnpm dlx shadcn@latest add @aceternity/background-beams

# Component will be added to: components/ui/background-beams.tsx
```

**Manual Installation:**

If the registry method doesn't work, install manually:

1. Install required dependencies:
```bash
bun add motion clsx tailwind-merge
# or: npm install motion clsx tailwind-merge
```

2. Add utility function to `lib/utils.ts`:
```typescript
import { clsx, type ClassValue } from "clsx"
import { twMerge } from "tailwind-merge"

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

3. Copy component code from [ui.aceternity.com](https://ui.aceternity.com) to your project

## Secure Installation

This setup runs multiple remote code executions (`create-next-app`, `shadcn init`, `shadcn add`). Before installing, follow supply chain security best practices:

- **Block post-install scripts** — `npm config set ignore-scripts true` (or Bun: disabled by default)
- **Cooldown period** — Wait 7 days for new package versions to be vetted by the community
- **Audit before installing** — Run `socket package score npm <pkg>` or use `socket npm install <pkg>` to check packages

Load the `dependency-upgrade` skill for full security configuration including Socket CLI integration, cooldown setup, lockfile validation, and CI enforcement.
