The requirement to be a PWA

For PWAs it must have some technical features such as HTTPS (secure contexts), Service Workers, and a Manifest file. Let us discuss all of them

HTTPS-Hypertext Transfer Protocol Secure

Your web app must be served over a secure network that follows the certain minimum standards of authentication are to be met. The primary goal of this is to prevent the MITM attackers from powerful API which further compromises an attack of the victim. Being a secure site is a best practice and makes your application a trusted one for many private uses such as secure transactions, etc. Most of the PWAs features such as geolocation and service workers are made been available only it is loaded using HTTPS.

Service Workers

It is a script that allows the control and intercepting of how a web browser handles its asset caching and network requests. It essentially acts as proxy servers between a web browser and a web application. It also provides the access to background Sync API and push notification. With the use of the service workers the developer can create web pages and other offline experiences in a faster way.

Manifest file

The JavaScript Object Notation (JSON) file makes your app discoverable and controls how it must appear to the user. It is responsible for the start ULR, icon, and name of the app, and all of the other necessary details for transforming the web into an app-like format.
