Progressive web app (PWA) is a term used to denote web applications that use latest web technologies.

Progressive web apps, also known as Installable Web Apps or Hybrid Web Apps, are regular web pages or websites, but can appear to the user like traditional applications or native mobile applications.

More clearly, a progressive web app (PWA) is a web application that can be installed on your computer. PWAs are websites that use recent web standards to allow for installation on user’s computer, and deliver an app-like experience to those users.

It works offline when you don’t have an internet connection, leveraging data cached during your last interactions with the app.

In 2015, designer Frances Berriman and Google Chrome engineer Alex Russell coined the term “Progressive Web Apps” to describe apps taking advantage of new features supported by modern browsers, including service workers and web app manifests, that let users upgrade web apps to progressive web applications in their native operating system (OS).

Why it is important to build your web app into PWA?

The answer is very simple, when you built you web app into PWA, your application will load much faster and it will give users a better experience.

And having a cache-first service worker strategy will allow your application to work offline, weaken one of the biggest issues with web apps.

Adding PWA support is important so people with slow connections and affordable smart phones can use your web application more easily.

PWAs are useful for apps like Twitter and news sites because they have a lot of text that you’ll read, but not necessarily interact with. Having it as a PWA allows you to open the app, loads its data, then read it contents later when you’re offline.

PWAs are the way of future, and the now. Most browsers support it, with notably absent support in safari. But in future, they also need to accept it.
