What is a Progressive Web App?
A Progressive Web App (PWA) is a web application that leverages modern web capabilities and delivers an app-like experience to users. No, they are not the same as traditional web apps. The main motive for building PWAs isis to be fast, reliable, and engaging, even in poor network conditions.
The best thing about PWA is that they can work offline, send push notifications, and also users can add them to the home screen of mobile devices. These all features provides users with native app experience without having to download it from an app store.
Progressive Web Apps combine the best of both worlds; it provides the accessibility of the web and the user experience of native apps.
In one-line, progressive web apps are websites that behave like apps and offers smooth performance and functionality. Below are some of its features for which Progressive web apps are currently become the favorite of start-ups and developers.

How Do PWAs Work?
Now that we know the features of the PWA apps, let’s move on to the working process. At the core of PWAs utilizes several key technologies that provide unique features:
- Service Workers: These are the scripts responsible to handle caching, offline functionality, and background data synchronization. Browsers runs service worker script in the background, separate from the web page. Service workers intercept network requests and allowing Progressive Web Apps to work offline by serving cached content when user is using the application in offline mode.
- App Shell: The app shell is a minimal HTML, CSS, and JavaScript structure that loads quickly and provides the basic framework for the user interface. Once the minimal structure is loaded, the content will be dynamically fetched and creates a smooth user experience.
- Manifest File: Manifest files are basically a JSON file that are responsible to provide metadata about the PWA, including, the app name, icons, theme colors, and how the app should behave when launched. The manifest file allows the app to be installed on the user’s device and appears as a full-screen app without browser elements.
These are the three basic structure that progressive web apps utilizes to work smoothly and provides users with enhanced native like application feels. Now, let’s dive into the core technologies that the PWAs utilize.

Why Should You Use PWAs?
There are several compelling reasons why businesses and developers should consider adopting PWAs:

- Offline Access: Progressive web apps can work offline and in the areas with low network. These apps use service worker and use cache memory to fast load the application and also users can interact with previously viewed content even without an internet connection.

This eliminates the need to go through lengthy app store approval processes.
- Cost-Effective Development: Developing a PWA is more cost-effective than creating separate native apps for different platforms (e.g., iOS and Android). Progressive Web Apps are cross-platform, meaning they can run on any device with a modern browser. This saves development time and reduces maintenance costs.
