Progressive Web Apps (PWAs) are web apps that are progressively enhanced. The progressive enhancements include app-like features, such as installation, offline support, and push notifications. You may also package your PWA for app stores. Possible app stores include the Microsoft Store, Google Play, Mac App Store, and more. The Microsoft Store is the commercial app store built into Windows 10.

The following guide gives you an overview of PWA basics by creating a simple web app and extending it as a PWA. The finished project works across modern browsers.
Tip
You may use PWABuilder to create a new PWA, enhance your existing PWA, or package your PWA for app stores.
Prerequisites
- Use Visual Studio Code to edit your PWA source code.
- Use Node.js as your local web server.
Create a basic web app
To create an empty web app, follow the steps in Node Express App Generator, and name your app MySamplePwa
.
In the prompt, run the following commands.
The commands create an empty web app and install any dependencies.
You now have a simple, functional web app. To start your web app, run the following command.
Now browse to http://localhost:3000
to view your new web app.
Get started building a PWA
Now that you have a simple web app, extend it as a PWA by adding the three requirements for PWAs: HTTPS, a Web App Manifest, and a Service Worker.
Step 1 - Use HTTPS
Key parts of the PWA platform, such as Service Workers, require the use of HTTPS. When your PWA goes live, you must publish it to an HTTPS URL.
For debugging purposes, Microsoft Edge also permits http://localhost
to use the PWA APIs.
Publish your web app as a live site, but ensure your server is configured for HTTPS. For example, you may create an Azure free account. Host your site on the Microsoft Azure App Service and it is served over HTTPS by default.
The following guide, use http://localhost
to build your PWA.
Step 2 - Create a Web App Manifest
A Web App Manifest is a JSON file containing metadata about your app, such as name, description, icons, and more.
To add an app manifest to the web app:
In Visual Studio Code, choose File > Open Folder and choose the
MySamplePwa
directory you created earlier.Select
Ctrl
+N
to create a new file, and paste in the following code snippet.Save the file as
/MySamplePwa/public/manifest.json
.Add a 512x512 app icon image named
icon512.png
to/MySamplePwa/public/images
. You may use the sample image for testing purposes.In Visual Studio Code, open
/public/index.html
, and add the following code snippet inside the<head>
tag.
Step 3 - Add a Service Worker
Service workers are the key technology behind PWAs, enabling scenarios like offline support, advanced caching, and running background tasks previously limited to native apps.
Service workers are background tasks that intercept network requests from your web app. Service workers attempt to complete tasks, even when your PWA is not running. Tasks include the following actions.
- Serving requested resources from a cache
- Sending push notifications
- Running background fetch tasks
- Badging icons
- and more
Service workers are defined in a special JavaScript file. For more information, navigate to Using Service Workers and Service Worker API.
To build a service worker in your project, use the Cache-first network service worker recipe from PWA Builder.
Navigate to pwabuilder.com/serviceworker, select the Cache-first network service worker, and select the Download button. The downloaded file contains the following files:
pwabuilder-sw-register.js
pwabuilder-sw.js
Copy the downloaded files to the
public
folder in your web app project.In Visual Studio Code, open
/public/index.html
and add the following code snippet inside the<head>
tag.
Your web app now has a service worker that uses the cache-first strategy. You new service worker fetches resources from the cache first, and from the network only as needed. Cached resources include images, JavaScript, CSS, and HTML.
Use the following steps to confirm that your service worker runs. Download microsoft office publisher for mac.
Navigate to your web app using
http://localhost:3000
. If your web app is not available, run the following command.In Microsoft Edge, select
F12
to open the Microsoft Edge DevTools. Select Application, then Service Workers to view the service workers. If the service worker is not displayed, refresh the page.View the service worker cache by expanding Cache Storage and select pwabuilder-precache. All of the resources cached by the service worker should be displayed. The resources cached by the service worker include the app icon, app manifest, CSS, and JavaScript files.
Try your PWA as an offline app. In Microsoft Edge DevTools (
F12
), choose Network then change the Online status to Offline.Refresh your app and it should display the offline mechanism for serving the resources of your app from the cache.
Add push notifications to your PWA
You may create PWAs that support push notifications by completing the following tasks.
- Subscribe to a messaging service using the Push API
- Display a toast message when a message is received from the service using the Notifications API
Just like with Service Workers, the push notification APIs are standards-based APIs. The push notification APIs work across browsers, so your code should work everywhere that PWAs are supported. For more information about delivering push messages to different browsers on your server, navigate to Web-Push.
The following steps have been adapted from the Push Rich Demo in Service Worker Cookbook provided by Mozilla, which has a number of other useful Web Push and service worker recipes.
Step 1 - Generate VAPID keys
Push notifications require VAPID (Voluntary Application Server Identification) keys in order to send push messages to the PWA client. There are several VAPID key generators available online (for example, vapidkeys.com). After generation, you should get a JSON object containing a public and private key. Save the keys for later steps in the following tutorial. For information about VAPID and WebPush, navigate to Sending VAPID identified WebPush Notifications using the Mozilla Push Service.
Step 2 - Subscribe to push notifications
Service workers handle push events and toast notification interactions in your PWA. To subscribe the PWA to server push notifications, ensure the following conditions are met.
- Your PWA is installed, active, and registered
- Your code to complete the subscription task is on the main UI thread of the PWA
- You have network connectivity
Before a new push subscription is created, Microsoft Edge verifies if the user granted the PWA permission to receive notifications. If not, the user is prompted by the browser for permission. If the permission is denied, the request to registration.pushManager.subscribe
throws a DOMException
, which must be handled. For more on permission management, navigate to Push Notifications in Microsoft Edge.
Chrome Web App Store
In your pwabuilder-sw-register.js
file, append the following code snippet.
For more information, navigate to PushManager and Web-Push.
Step 3 - Listen for push notifications
After a subscription is created in your PWA, add handlers to the service worker to respond to push events. Push event are sent from the server to display toast notifications. Toast notifications display data for a received message. To complete the following tasks, you must add a click
handler.
- Dismiss the toast notification
- Open, focus, or open and focus any open windows
- Open and focus a new window to display a PWA client page
In your pwabuilder-sw.js
file, add the following handlers.
Step 4 - Try it out
To test push notifications for your PWA, complete the following steps.
Navigate to your PWA at
http://localhost:3000
. When your service worker activates and attempts to subscribe your PWA to push notifications, Microsoft Edge prompts you to allow your PWA to show notifications. Select Allow.Simulate a server-side push notification. With your PWA opened at
http://localhost:3000
in your browser, selectF12
to open the DevTools. Choose Application > Service Worker > Push to send a test push notification to your PWA.A push notification should display near the taskbar.
If you do not select (or activate) a toast notification, the system automatically dismisses it after several seconds and queues it in your Windows Action Center.
Next steps
The following steps include additional tasks to help you understand building real-world PWAs.
- Manage and store push subscriptions
- Encrypt payload data
- Responsive design
- Deep-linking
- Implement validation and testing practices such as Webhint
