Steps to Migrate a Website into Progressive Web App

Step 1- Load URL 

The first step involves cloning the GitHub repository using a command line:

$ git clone

With this, a Migrate to PWA directory will be created with full coding for every single step. You have to upload the work file for this particular codelab and then make the required changes.

After your code gets checked out, “Simple HTTP Server Application” will be used to serve the work file on port 8887. Once you are done with this, you can load the URL easily.

Step 2- Check the Website on Mobile

If you have plugged in your Android device with desktop, type the URL- chrome://inspect. You can access your website at http://localhost:8887/ on your Android phone.

Step 3- Addition of Modern Head Tags 

First, you have to make your website mobile-friendly and then you have to include Web App Manifest. The manifest will contain the meta-information of the website.

Add these lines if you don’t have any templating engine:


<meta name= “viewport” “content=width-width, user-scalable=no” />

<link rel=”manifest” href=”manifest.json” />



This element is useful in making the website responsive. Once you write this code, you will notice that your website adjusts with the device properly when it is reloaded.


Within the second line of the coding, you have provided reference to the file. This is useful for showing how your website will be added on the home screen. Once you are done with this, open the text editor. Now, you have to write JSON. Within the short_name section, you have to mention what will be displayed on the home screen.

Save down the file with manifest.json nomenclature. After this, reload the page on the Android device and choose “Add to Home Screen” from the top-right menu. This will help in showing the icon on the home screen.

Step 4- Adding of Service Worker

Service Workers contain a background script that a browser will run when the user is not using the page. This element is best for rendering quality offline support.

Build a Service Worker

Get this code copied in a new file and save as sw.js.

/ ** An empty service worker! */

self.addEventListener (‘fetch”, function(event) {

/ ** An empty fetch handler! */


Registration of Service Worker

The next thing is the registration of code within the website’s code. For this purpose, you have to open the site.js file and add this:

navigator.serviceWorker && navigator.serviceWorker.register(‘./sw.js’).then(function(registration) {  console.log(‘Excellent, registered with scope: ‘, registration.scope);});

Due to this, the code execution will be done for every single page loading.

Step 5- Make Your Website Work Offline

For this, you have to open sw.js script and get access to cached objects. After getting this, code updating has to be done to cache the website.

Check out whether it is working or not. You have to uninstall the existing app and load it using Chrome. After this, refresh the page and click on the “Add to Home Screen” button.

That’s it. You have successfully completed the migration process of the website to the progressive web app.
