The Technologies behind PWA

The PWA proposal is to make websites feature the features of native apps, such as offline operation, auto update, and push notifications, without the need for the user to download all application data.

Speaking in a more technical way, the PWA methodology is an enhancement of Web technologies. It can also be seen as a combination or hybrid evolution between websites and mobile applications. It is a new innovation for an e-commerce business. Hire PWA MPS Company to get this innovation for your e-commerce business as well.

There are a number of Web technologies behind every PWA methodology, they are:

  • Service worker
  • Cache API
  • Push notifications
  • Web app manifest

Even if you are not a developer, being aware of what these technologies are and knowing how they work within PWA is very important to be able to understand the potential that it presents. Below I will explain to you, in a summarized way, how each one behaves and what it influences in this methodology.

1. Service worker

The Service worker is a system that intercepts the requests of the application and saves the results on the client side. This allows extremely fast data consumption speed and allows the application to work offline. It acts as a kind of cache, as we already know.

2. Cache API

Cache API is a way to store the requests made locally so that when requested again, they work more efficiently. This concept consists of saving a copy of a request or a specific route in order to use it again so that it can be consumed one more time without the need to make a new request.

3. Push notifications

This is likely to be the tool we are most familiar with since it is used by all Apps to alert us about updates, news, signs of non-use, and other information.

Push notifications are used to notify users of certain services about various features. They are common in Mobile Apps, and mostly they tell you something new. An example of this technology is WhatsApp messages that are notified on your mobile phone or when someone enjoys your photo on Instagram.

4. Web App Manifest

In accordance with Google’s Web Fundamentals, Web App Manifest is a document that aims to standardize Web applications, which allows the user to add a website icon on their home screen without having to download an application.
