Complete Guide to Turn Website into Progressive Web App
                     
Steps to Turn a 
Website into PWA
Step 1: Build a Basic Web 
Page
Create a simple webpage using HTML, CSS, and 
JavaScript. This serves as the foundation of your PWA. 
Ensuring a basic functional site is crucial as it will be 
progressively enhanced with PWA features, providing 
the necessary groundwork for further development.
Step 2: View the Website on Your 
Mobile
Access the website on a mobile device to check its 
responsiveness and performance. This step is 
important to ensure the site adapts well to different 
screen sizes and functions correctly on mobile, 
providing a baseline for enhancements. 
Enter chrome://inspect into your URL bar if you have 
an Android device connected in to your desktop 
computer.
Step 3: Add Modern Head 
Include vieTwapogrst and manifest tags in the website’s HTML 
head section. The viewport tag ensures mobile 
responsiveness, while the manifest file provides 
metadata for the web app. These tags are essential for 
creating a mobile-friendly and app-like user experience.




Step 4: Create a 
Manifest File
Develop a manifest file in JSON format that includes 
app metadata like name, icons, and start URL.  
This file allows users to add your site to their home 
screen, making it behave more like a native app, thus 
enhancing user engagement and accessibility.
Step 5: Add a Service 
ImplemeWnt oar skeervrice worker script to handle caching 
and background tasks. Service workers are vital for 
enabling offline functionality and improving load times, 
as they cache resources and manage network 
requests efficiently.
/** An empty service worker! */
self.addEventListener (‘fetch’, function(event)
{
/** An empty fetch handler! */
});
And that’s it.
Step 6: Make the Website Work 
Offline
Open the `sw.js` script and obtain the cache object. 
Update the code to cache the entire website. Check 
functionality by removing the current app, opening it 
in Chrome, and selecting “Add to Home Screen.” 
Ensure the service worker reloads and caches changes 
by adding a component with its version, so the 
installation process repeats whenever updates occur.
Step 7: 
Testing
Thoroughly test the PWA using tools like Chrome 
DevTools and Lighthouse to check performance, offline 
functionality, and responsiveness.
Testing is crucial to identify and fix issues, ensuring a 
reliable, high-quality user experience across various 
devices and scenarios.
