3. Customizing Install Prompts

To customize the install prompt, follow these steps:

1. Listen for the beforeinstallprompt event.
2. Prevent the default prompt from showing automatically.
3. Store the event for later use.
4. Trigger the prompt at an appropriate time.

3.1 Code Example

window.addEventListener('beforeinstallprompt', (e) => {
    // Prevent the default install prompt
    e.preventDefault();
    // Store the event for later use
    let deferredPrompt = e;

    // Show the custom install button
    const installButton = document.getElementById('installBtn');
    installButton.style.display = 'block';

    installButton.addEventListener('click', () => {
        // Show the install prompt
        deferredPrompt.prompt();
        // Wait for the user to respond to the prompt
        deferredPrompt.userChoice.then((choiceResult) => {
            if (choiceResult.outcome === 'accepted') {
                console.log('User accepted the install prompt');
            } else {
                console.log('User dismissed the install prompt');
            }
        });
    });
});
            

4. Best Practices

• Design a user-friendly UI for the install prompt.
• Show the prompt at strategic times, like after a user has engaged with the app.
• Provide clear information about the benefits of installing the app.
• A/B test different placements and wording of the prompt.
