Similar to the apple that fell on Newton’s head and changed the way we understood gravitational forces, progressive web apps are changing the way we understand applications by providing an app-like experience in the web form.

Progressive web apps are one of the technologies originally proposed by Google. The term progressive web app was first uttered by Frances Berriman and Alex Russell in 2015.

It was a way of describing applications that take advantage of new features supported by modern browsers, including service workers and web app manifests, and also lets users upgrade web apps to progressive web applications regardless of their native operating system.

PWAs are also described as user experiences that have the reach of the web and are characterized by the following by Google.

• Reliable — Load instantly and never show the downasaur (a.k.a the T-Rex), even in uncertain network conditions.
• Fast — Respond quickly to user interactions with silky smooth animations and no janky scrolling.
• Engaging — Feel like a natural app on the device, with an immersive user experience.
