Building a Flexible Share System in React with the Web Share API

Tired of bloated websites weighed down by multiple third-party sharing scripts? The Web Share API offers a streamlined, performant alternative, leveraging your device's native sharing capabilities. This tutorial demonstrates building a modern, React-based sharing system.

Project Setup

Start by creating a new React project using Vite and TypeScript:

<code class="language-bash">npm create vite@latest my-share-app -- --template react-ts
cd my-share-app</code>

Install dependencies:

<code class="language-bash">npm install sonner</code>

For styling (optional, but recommended):

<code class="language-bash">npm install -D tailwindcss@3 postcss autoprefixer
npx tailwindcss init -p</code>

Add the sonner toast provider to your main App component:

<code class="language-typescript">// src/App.tsx
import { Toaster } from 'sonner';

function App() {
  return (
    <>
      <Toaster position="bottom-right" />
      {/* Your app content */}
    </>
  );
}</code>

Understanding the Web Share API

The Web Share API offers a platform-native sharing experience, integrating seamlessly with your device's built-in sharing mechanisms. This provides a consistent user experience across mobile and desktop.

Creating the Share Hook

Let's create a custom hook (src/hooks/useShare.ts) to manage sharing logic:

<code class="language-typescript">import { toast } from "sonner";

const useShare = () => {
  const copy = async (text: string) => {
    try {
      await navigator.clipboard.writeText(text);
      toast.success(`Copied ${text} to clipboard!`);
    } catch (error) {
      console.error("Clipboard copy error:", error);
      toast.error("Clipboard copy failed.");
    }
  };

  const share = async (url: string, title: string, description: string) => {
    if (navigator.share) {
      try {
        await navigator.share({ title, text: description, url });
        console.log("Share successful!");
      } catch (error) {
        console.error("Sharing error:", error);
        toast.error("Sharing failed.");
        copy(url); // Fallback to copy
      }
    } else {
      console.error("Web Share API not supported.");
      toast.error("Web Share API not supported. Copying URL instead.");
      copy(url); // Fallback to copy
    }
  };

  return { copy, share };
};

export default useShare;</code>

Implementation Breakdown

useShare provides:

1. copy: A clipboard fallback using the Clipboard API.
2. share: Prioritizes the Web Share API, falling back to copy if unavailable or unsuccessful.

This approach ensures a robust sharing experience across various browsers and devices.

Using the Hook in Components

Here's a ShareButton component (src/components/ShareButton.tsx):

<code class="language-typescript">// src/components/ShareButton.tsx
import { FC } from 'react';
import useShare from '../hooks/useShare';

interface ShareButtonProps {
  url: string;
  title: string;
  description: string;
}

const ShareButton: FC<ShareButtonProps> = ({ url, title, description }) => {
  const { share } = useShare();

  const handleShare = () => {
    share(url, title, description);
  };

  return (
    <button onClick={handleShare}>Share</button>
  );
};

export default ShareButton;</code>

And its usage in App.tsx:

<code class="language-typescript">// src/App.tsx
import ShareButton from './components/ShareButton';

function App() {
  return (
    <div className="p-4">
      <h1>My Awesome Content</h1>
      <ShareButton 
        url={window.location.href} 
        title="Check out this content!" 
        description="Interesting article about the Web Share API..." 
      />
    </div>
  );
}</code>

Browser Support and Considerations

The Web Share API enjoys broad support on modern mobile and desktop browsers. Remember:

• Secure context (HTTPS) is required.
• User interaction (e.g., button click) is necessary.
• Not all data types are universally supported.

Best Practices

• Always include fallbacks.
• Handle errors gracefully. Inform users of success or failure.
• Keep it simple. A clear, concise button is sufficient.
• Thoroughly test across devices.

Conclusion

The Web Share API offers a superior alternative to traditional sharing methods. By combining it with React and thoughtful error handling, you can create a seamless, native sharing experience for your users. Give it a try in your next project!
