Progressive Web Apps (PWA) Architecture

 Progressive Web Apps (PWA) Architecture: Progressive web apps are web applications that use modern web technologies to provide a mobile app-like experience to users. PWAs can be installed on a user's device, work offline, and have push notification capabilities. The architecture of PWAs typically involves a client-side JavaScript framework, a server-side API, and a service worker that enables offline capabilities. Here is an example of a PWA using React:

javascript

// App.js

import React from 'react';

import logo from './logo.svg';

import './App.css';

function App() {

  return (

    <div className="App">

      <header className="App-header">

        <img src={logo} className="App-logo" alt="logo" />

        <p>

          Edit <code>src/App.js</code> and save to reload.

        </p>

        <a

          className="App-link"

          href="https://reactjs.org"

          target="_blank"

          rel="noopener noreferrer"

        >

          Learn React

        </a>

      </header>

    </div>

  );

}

export default App;

In this code, we create a simple React app that displays a logo and some text.
