What is PWA, or Progressive web app

Progressive web app (PWA) – is a web application, designed according to the “mobile first” principle, launched just like a regular website. Unlike the standard one, with the help of a Service Worker script, its content is automatically saved in the device, so the data can be retrieved later, even in offline mode.

The aim of this solution is, among other things, to fill the space between websites and mobile applications, betting on the use of modern technologies (offline operation, push notifications, welcome screens).

Additionally, PWA is committed to the highest quality web experience, regardless of the level of internet connection, and across all operating systems. A progressive application can be created with a trimmed budget, because it does not generate as high costs as creating a mobile one.  

Progressive web app solves a significant portion of companies’ problems, including slow-loading pages. Market giants (AliExpress, Alibaba, Tinder, Twitter) are already using PWA as part of their business model. By doing so, they are seeing increases in conversions across all browsers, increasing the number of page visits, and increasing the time spent on the site per session, confirming the potential of progressive applications.

Mobile apps written in this technology deliver a completely new quality of mobile experience, with significantly less effort. They allow you to fully exploit the potential of mobile devices by combining the advantages of both desktop and application. The technology is rapidly gaining popularity, especially considering the fact that the number of mobile device users is increasing.

PWA in comparison to standard solutions based on the “mobile first” model provide high user comfort, among other things because they do not need to be downloaded from the store, and there is no need for updating. They take up much less disk space, because they can be used from the browser level.

Fast loading, when first opened such a page should become  interactive in less than 10 seconds on a 3G connected device, and even faster on newer versions. These features improve new user acquisition – you can use them right away, without having to download or register.

Downsides of progressive apps include the fact that they have some limitations. Due to the fact that they are written in JavaScript, they are not as optimized and efficient as standard apps written in Kotlin or Swift. Additionally, since iOS 11.3, they can be run on Apple hardware, but compatibility with older devices is still lacking.
