What Is A Progressive Web Application?

A progressive web app (PWA) is the amalgamation of the technologies of web and mobile apps that act as a website but render you the feeling of running an application. The rapid advancement in browser technology, availability of push APIs, and cache have enabled web developers to install website applications on the home screen and provide regular notifications of the website’s latest updates in the offline mode.

But what is the need of putting your website-like application on the home screen of PCs or smartphones? The answer is clear as real, to exterminate the unwanted need of opening a browser or installing applications.

You don’t have to go through the dull process of visiting the play store, finding the application, installing the application, and then starting using it. From the website, you can install the PWA with a single click and you can use the app right away even in offline mode. Progressive web apps have push notifications, which gives them a better retention rate than their counterparts with no push notification option.

According to Statista, the total number of smartphone users worldwide is predicted to reach 3.8 billion in 2021. This is more than half of the world’s population!

How Progressive Web Apps Work?

PWAs, or Progressive Web Apps, are web applications designed to work like native apps on your device. They are built using web technologies like HTML, CSS, and JavaScript and can be accessed through a web browser.

When you visit a PWA for the first time, your browser will download the necessary files, such as the HTML, CSS, and JavaScript code, as well as any media assets like images and videos. This is known as caching. Once the initial download is complete, the PWA can be accessed offline, a significant advantage over traditional web apps.

One of the key features of PWAs is their ability to provide a native-app-like experience. This is achieved by using a service worker, which acts as a middleman between the PWA and the browser. The service worker runs in the background, intercepts network requests made by the PWA, and can respond with cached data if the network is unavailable.

Another essential feature of PWAs is their ability to be installed on your device’s home screen, just like a native app. This allows them to have an icon, launch screen, and other features similar to native apps. This is achieved through a web app manifest technology, which defines the PWA’s metadata, such as its name, icons, and start URL.

Overall, PWAs provide a fast, reliable, and engaging user experience and are becoming an increasingly popular way to build web applications that rival native apps in terms of functionality and performance.

To Develop a Progressive Web App (PWA), You Will Need to Use Html, Css, and JavaScript. Here Is Some Basic Syntax to Get You Started

1. HTML Syntax:

<!DOCTYPE html>
    <title>My PWA</title>
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <link rel="manifest" href="/manifest.json">
    <link rel="icon" type="image/png" href="/images/icons/icon-72x72.png">
    <h1>Hello, World!</h1>

2. CSS Syntax:

body {
font-family: sans-serif;
background-color: #f2f2f2;

h1 {
font-size: 2rem;
color: #333;

3. JavaScript Syntax:

// Register service worker
if ('serviceWorker' in navigator) {
.then(function() {
console.log('Service worker registered!');

// Install service worker
self.addEventListener('install', function(event) {
console.log('Service worker installed!');

// Fetch assets from cache
self.addEventListener('fetch', function(event) {
.then(function(response) {
return response || fetch(event.request);

These are just some basic syntax examples. You will need to learn more advanced concepts and techniques to develop a complete PWA, or you can Connect With Us to convert your app idea into reality

Key Characteristics Of Progressive Web Applications

There are numerous characteristics of progressive web apps, and we are going to state the top-notch ones here.

1. PWA Provides App-Like Experience

PWAs offer a full-screen experience and look like a native application. Moreover, progressive web apps have minimal page refreshes.

2. Linkable

One of the principal characteristics of the progressive web app is its linkability. Users can easily share or bookmark the app’s URL whenever they want, and the app can retain or reload its state at the same time.

3. Discoverable

A progressive web application is a website with an application-like experience in the original sense. Therefore, it should be easily discoverable on the search engine result page, and it is one of the biggest advantages of progressive web apps over native applications.

4. Responsiveness

A fully-fledged progressive web application must be able to fit all screens sizes and provide a great user experience.

5. Progressive

Hereby progressive we mean PWAs should be able to harness all attributes of the platform, must function on any device seamlessly, and augment progressively.

6. Easy to Install

You can effortlessly install progressive web apps on any device and make the content ready to read in no time.

7. Safe

A progressive web app should be hosted over HTTPS to prevent external threats hampering the website’s performance. The job of a progressive web application is to provide an alluring and intimate user experience.

Three App Pillars Of PWA

1. Web Is Capable

Today’s web is quite capable on its own. WebRTC, geolocation, and push notifications, for example, might be utilized to build hyper-local video chat software. You may install that software and virtualize the talks using WebGL and WebVR. Developers may now use WebAssembly to access other ecosystems, such as C, C++, and Rust, and bring decades of labor and capabilities to the web.

2. Reliable Progressive Web App

A reliable Progressive Web App feels speedy and dependable regardless of the network, and responsible applications must be accessible regardless of network connection. Users expect apps to run even if their network connection is weak or unpredictable or when they are not connected to the internet. Even if initiating a request to your server is onerous, customers want the most current material they have interacted with, such as media tracks, tickets, and itineraries, to be available and usable. When a request isn’t feasible, they like to be notified rather than failing or crashing silently.

3. Installed Progressive Web Apps

Progressive Web Apps that have been installed operate in their window rather than in a browser tab. When a Progressive Web App transitions from a tab to a standalone app window, it alters how users see and interact with it.

The Difference Between PWA & AMP

Though there are monumental differences between progressive web apps and accelerated mobile pages, the primary purpose of both technologies is to serve users’ content pieces in a faster, secure, and more engaging way. While progressive web apps harness browsers’ functionalities, AMP is a stripped-down web page version comprising HTML, CSS, and Javascript.

  • PWA is a website page that provides the app-like experience while AMP or accelerated mobile pages is the most basic version of a web page without code clutter.
  • PWA functions swiftly in comparison to AMP pages.
  • PWA harness the push notification attribute that augments users’ retention rate but AMP lacks this attribute.
  • PWA provides the entire information on a web page as the way it is. While AMP exterminates a lot of scripts from the web page to amplify the speed and conversion rate simultaneously.
  • Progressive web apps have the knack to access content even in the offline mode. But that’s not the case with AMP.
  • When compared to AMP, PWA consumes a very low network to open up. But AMP pages rank higher than normal webpages.
