What exactly is a PWA?

A Progressive Web App is a web app that uses modern web capabilities to deliver an app-like experience to users.

Why is it the alternative to mobile?

Safety for front-end, which is crucial for every business, especially if you have seasonal traffic peaks
Super fast front-end wherein a customer has a feeling of immediate interaction, similar to well-built mobile applications
Off-line readiness where the on-line store can be browsed by customers with weak or even lack of a network connection
Mobile-first experience with no reloads of pages and animations
Cheaper than native apps – they can be used by every possible smartphone user in the world.

The company concluded that the decoupling of these individual services is best served by a multipage app.
As a user browses around the PWA, different routes are loaded. analyzed the critical routes that users care about most, created a webpack plugin to collect the dependencies of these critical routes, and then precached these routes when they install a service worker on the user’s client browser.
