What are Progressive Web Apps and why they are important?

Progressive web apps are a relatively new, however popular concept in the Information Technology fraternity. So, while building for the web, considering PWA is a worthwhile decision.
In this article, we will understand the Progressive Web Apps (PWA) basics, PWA features, and importance.

What is a Progressive Web App?

A Progressive Web App abbreviated as PWA is a term used to underline a new software development methodology. PWAs utilize modern web capabilities on web pages to deliver a modern app-like experience. They typically progress from being regular web pages to impressive, top-level apps – ensuring enriched user experience.
Simply put, Progressive Web Apps combine the best of both worlds – websites and mobile apps!
You might ask, how does a progressive web app do it? How does it ensure that the web page you see on your preferred browser progresses to offer a mobile app like interface?
It happens with the following PWA specific features:

Security contexts (HTTPS):

Security is the foundation of Progressive web apps. Serving the web application over a secured network establishes the web application as a trusted site. It plays a vital role when users are to perform secure transactions.
To make service workers available, it’s the foremost step to load the PWA using https.
Service workers:
Progressive Web Apps deliver what users really want – speed, performance and ease of access. Service workers are responsible for achieving these characteristics for a PWA. A service worker is a script that runs in the background, separate from the web page. It controls how the browser handles its network requests and enables intelligent asset caching. Furthermore, it facilitates background content updating and offline functionality (after the first load, the previously visited websites/apps will run faster even on fluctuating network connection) among other efficiency contributors.

Manifest files:

These are generally a JSON file that contains the PWA name, its start URL, icons and other details required for delivering the distinct app-like experience on the web page. In simple terms, the manifest files control the appearance of the app and ensure that the PWA is discoverable.
