In the modern era, almost all the peoples were connected to the web. We’re not even ready to imagine a world without mobile or internet.

Having all this on the mind, Progressive Web Apps are introduced. The biggest motive of this app is to retain the user even from the very first visit to the website. Mostly, we can achieve it by cached data. Like how it has been achieved with the mobile apps.
Before exploring all, Let’s focus what Progressive Web App is,

While we are surfing the web, We do come across loads of irrelevant information’s.
Even sometimes internet will feed us with excess content when we need a drop of precise information.
So don’t get confused, or don’t be over stuffed with irrelevant information.

To get start with PWA, technically it’s should meet below four requirements,


  • A site must be visited twice with a 5-minute interval
  • A website should have valid HTTPS connection.
  • Must have Valid JSON Manifest

Once those four requirements satisfied, You can get ready to customize the functionalities to implement full offline browsing.
