Step-by-Step: Embed Testimonials in React

Step 1: Create Your ProofWall Account

1. Sign up at ProofWall.
2. Create a project for your React application.
3. Collect or import your testimonials.

Step 2: Configure Your Widget

1. Go to your ProofWall dashboard.
2. Navigate to "Widgets" in your project.
3. Customize the appearance to match your app's design.
4. Copy the widget ID from the embed code.

Step 3: Integrate in React

Method 1: Using useEffect Hook

Create a reusable component for your testimonials:

// components/ProofWallWidget.jsx
import { useEffect, useRef } from 'react';

const ProofWallWidget = ({ widgetId }) => {
  const containerRef = useRef(null);

  useEffect(() => {
    // Create script element
    const script = document.createElement('script');
    script.src = `https://www.proofwall.com/api/widget/${widgetId}`;
    script.async = true;
    
    // Append to container
    if (containerRef.current) {
      containerRef.current.appendChild(script);
    }

    // Cleanup on unmount
    return () => {
      if (containerRef.current) {
        const existingScript = containerRef.current.querySelector('script');
        if (existingScript) {
          containerRef.current.removeChild(existingScript);
        }
      }
    };
  }, [widgetId]);

  return (
    <div ref={containerRef}>
      <div id="proofwall-widget"></div>
    </div>
  );
};

export default ProofWallWidget;

Usage:

import ProofWallWidget from './components/ProofWallWidget';

function TestimonialsPage() {
  return (
    <section className="testimonials-section">
      <h2>What Our Customers Say</h2>
      <ProofWallWidget widgetId="YOUR_WIDGET_ID" />
    </section>
  );
}

Method 2: Using Next.js Script Component

If you're using Next.js, you can use the built-in Script component:

// pages/index.js or app/page.js
import Script from 'next/script';

export default function Home() {
  return (
    <>
      <section className="testimonials">
        <h2>Customer Testimonials</h2>
        <div id="proofwall-widget"></div>
      </section>
      
      <Script 
        src="https://www.proofwall.com/api/widget/YOUR_WIDGET_ID"
        strategy="lazyOnload"
      />
    </>
  );
}

Method 3: Using dangerouslySetInnerHTML (Quick Setup)

For a quick integration without a separate component:

function Testimonials() {
  return (
    <div 
      dangerouslySetInnerHTML={{
        __html: `
          <script src="https://www.proofwall.com/api/widget/YOUR_WIDGET_ID"></script>
          <div id="proofwall-widget"></div>
        `
      }}
    />
  );
}

Step 4: Styling and Customization

ProofWall widgets are fully customizable. You can also add wrapper styles:

<div className="max-w-4xl mx-auto py-12">
  <ProofWallWidget widgetId="YOUR_WIDGET_ID" />
</div>

React Best Practices

• Lazy loading — Load the widget only when it's visible using Intersection Observer.
• Error boundaries — Wrap the widget in an error boundary for graceful failures.
• TypeScript support — Add proper types to the ProofWallWidget component props.
• SSR considerations — The widget loads client-side, so it works with SSR frameworks like Next.js.

TypeScript Version

// components/ProofWallWidget.tsx
import { useEffect, useRef } from 'react';

interface ProofWallWidgetProps {
  widgetId: string;
  className?: string;
}

const ProofWallWidget: React.FC<ProofWallWidgetProps> = ({ 
  widgetId, 
  className = '' 
}) => {
  const containerRef = useRef<HTMLDivElement>(null);

  useEffect(() => {
    const script = document.createElement('script');
    script.src = `https://www.proofwall.com/api/widget/${widgetId}`;
    script.async = true;
    
    containerRef.current?.appendChild(script);

    return () => {
      const existingScript = containerRef.current?.querySelector('script');
      if (existingScript) {
        containerRef.current?.removeChild(existingScript);
      }
    };
  }, [widgetId]);

  return (
    <div ref={containerRef} className={className}>
      <div id="proofwall-widget"></div>
    </div>
  );
};

export default ProofWallWidget;
