How come my PWA isn't recognized and appearing for installation?

I have created a progressive web application (PWA) and have included the necessary manifest and service worker files. However, despite meeting all requirements, the PWA install prompt is not appearing on Chrome. The manifest.json file contains information such as the app's name, start URL, and icons, while the service worker handles offline caching and page preloading. Although the site functions correctly and serves cached pages, the install prompt is not displayed. Can you assist me in resolving this issue, please?

I'm sorry to hear that you are having trouble with the PWA install prompt not appearing on Chrome. There could be several reasons why this is happening. One reason could be that Chrome and Edge on iOS and iPadOS do not support PWA installation, so the beforeinstallprompt event can't fire. In this case, the only option is to open the PWA using Safari, where it is installable from the share, add to the home screen menu. Another reason could be that there is something wrong with your manifest file. You can check eligibility for PWA install prompt under the Applications tab in Chrome Dev Tools. If there is something wrong with your manifest file, it will show an error or warning. If neither of these reasons apply to you, then it could be a bug in Chrome. In some cases, although your app is a correct PWA, the install button does not show. As a workaround, you can restart Chrome by typing chrome://restart in the address bar. I hope this helps!

It is important to note that there are certain prerequisites that need to be met before the install prompt will be displayed on your Progressive Web App. First, the site must be served over HTTPS and must have a valid service worker installed. Second, the web app must be visited a few times before the install prompt will be displayed. If you have fulfilled all of these requirements and the install prompt is still not appearing, try the following steps: - Make sure that the start_url property in your manifest.json file is set correctly. The start_url should point to the URL of the page that you want users to see when they open your web app. - Ensure that your manifest.json file is linked correctly in your HTML file. You can do this by including the following code in the section of your HTML file:
<link rel="manifest" href="/path/to/manifest.json">
- Check that your service-worker.js file is registered correctly in your HTML file. You can do this by adding the following code to the bottom of your HTML file:
        if ('serviceWorker' in navigator) {
            window.addEventListener('load', function() {
                    .then(function() {
                        console.log('Service worker registered successfully');
                    .catch(function() {
                        console.log('Service worker registration failed');
These steps should help you troubleshoot any issues preventing the install prompt from being displayed on your PWA.
