⚙️ 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 string-line
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/StringLine.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.
⚠️ ScrollTrigger Plugin Notice
This component uses scroll-triggered timing events. Make sure to register the plugin as shown inside the code:
GSAP Registration
import { ScrollTrigger } from "gsap/ScrollTrigger";
gsap.registerPlugin(useGSAP, ScrollTrigger);4
Import & Render
Import and render the component in your page or view layout:
App Page
import StringLine from "@/components/StringLine";
export default function Page() {
return (
<main className="min-h-screen p-8 bg-[#f5f5f5] flex items-center justify-center">
<StringLine />
</main>
);
}💡
Customization & Component Properties
🛠️ Customization & Component Properties (Props)
You can pass the following settings to configure the layout and animation details:
nodes(Array): Floating node coordinate keys.pathD(string): The raw SVG path geometry definition.
