⚙️ Setup & Integration Guide

How to install, import, and configure this animation in your project

💻

Option A: Install via CLI (Recommended)

You can install this component directly into your project via the TweenLabs CLI. It automatically creates the file and configures dependencies:

npx tweenlabs add 3d-carousel

Option B: Manual Installation

Follow these steps to integrate the component into your project manually:

1

Install Packages

First, install GSAP and its official React hook helper library (@gsap/react).

npm install gsap @gsap/react
2

Add Required CSS Styles

Copy the styles from the Required CSS tab above, or open the styles.css file that was automatically downloaded with your component. Paste these classes into your global stylesheet (e.g. src/app/globals.css or similar).

3

Create Component File

Create a new file in your React or Next.js project (e.g. src/components/Carousel3D.tsx) and paste the code from the Standalone React Component tab above. If no standalone tab is available, copy the full page file code and adjust the routing logic for your needs.

4

Import & Render

Import and render the component in your page or view layout:

App Page
import Carousel3D from "@/components/Carousel3D";

export default function Page() {
  return (
    <main className="min-h-screen p-8 bg-[#f5f5f5] flex items-center justify-center">
      <Carousel3D />
    </main>
  );
}
💡

Customization & Component Properties

🛠️ Customization & Component Properties (Props)

You can pass the following settings to configure the layout and animation details:

  • items (Array): An array of card specs containing category tags, image paths, descriptions, and color accents.
