Creating a custom install button for a Progressive Web App (PWA) involves capturing the `beforeinstallprompt` event and using it to trigger the installation process when the user clicks the button. Here's a step-by-step guide :
First, create a button or any other clickable element in your HTML that the user can interact with to install the app.
<button id="installApp">Install</button>The `beforeinstallprompt` event is fired when the app meets the criteria for installation. You can capture this event and prevent it from showing the default install prompt.
// javascript
let deferredPrompt;
window.addEventListener('beforeinstallprompt', (e) => {
e.preventDefault();
deferredPrompt = e;
});When the user clicks the install button, call the `prompt()` method on the `beforeinstallprompt` event
// javascript
const installApp = document.getElementById('installApp');
installApp.addEventListener('click', async () => {
if (deferredPrompt !== null) {
deferredPrompt.prompt();
const { outcome } = await deferredPrompt.userChoice;
if (outcome === 'accepted') {
deferredPrompt = null;
}
}
});Please note that the installation of a PWA is browser-dependent, so you cannot install it directly without a browser prompt. The user must confirm the installation. This is designed to prevent web pages from repeatedly prompting the user to install the web app.
