What is the progressive web app

The Progressive Web App, also known as PWA, lets you customize the site without having to design an app for Android or ios. If you visit some sites like the mobile version of Twitter with Google Chrome browser at https://mobile.twitter.com it will show you a request to add the site to your homepage after logging in. Now whenever you need to visit Twitter, simply click on the icon on your phone just like a separate app added to the homepage and log in to Twitter via the browser. These types of programs are called web applications or PWA.

In this article, we are going to introduce the web application (PWA) and get to know its features and structures. Then consider how to use it and see how well it can be used.

What is a web application or PWA? How to use them?

As we mentioned, the Progressive Web App is a web application that displays a website in the form of an app on smartphones. The technology, introduced by Google in 2015, has attracted a lot of attention because of the relative ease of development and instant user experience for users. Progressive software is attempting to introduce native software with the exception that it will display a website in a browser.

When you use these types of applications you will be redirected to the site you are browsing through. As a result, you do not need to occupy the memory space of your phone and RAM to install the app. It’s easy to do, and you can access your favorite content in a very compact version. When you visit any site that supports this feature, you are asked if you want to add the site to your homepage. Which is added to the phone if you like the site icon just like other apps?

You have a shortcut that does not need to keep the site addresses and you can easily surf the sites you have a lot to deal with.

What are the features of web apps?

Because this type of application is available on Android and ios phones, and besides, we have screens of different sizes, the following features must be taken into account when designing these types of applications.

• Searchability: Since progressive web applications are a website, they are searchable through search engines. This is a significant advantage over native apps.
• Progressive: A progressive web app as it is called should have a good interaction with a variety of browsers and operating systems. Regardless of the browser and device type, it can be used by all users and will not have design problems in different display sizes.
• User Engagement: Mobile application users are more likely to re-use a website than they are to re-visit a website. Progressive web apps have made up for this by using features like server-side notifications (Push Notification).
• Ability to install on any type of phone, tablet or desktop: Web applications nowadays are open to all operating systems. When you log in to sites like Instagram, Twitter, and so on, depending on the operating system and browser you are logged in, a request will be added to your homepage. So every web app should be compatible with all operating systems and browsers.
• Subscription: Progressive apps must have a unique URL for each part of their app. That is, when you access one of the text or product pages from the web application when using the share button, you must be able to use them correctly. It also works in some cases so that you can share content through the web app while subscribing through other apps.
• App Appearance: A progressive app is similar to the native app, uses a similar interface and has no differentiation than regular apps. Another characteristic is its responsiveness. These apps don’t matter what platform they run on; screen, laptop, smartphone, or tablet; the point is that the progressive software should be compatible with all platforms of whatever image size and elements across Visible to standard size.
• Secure: One of the requirements for using this type of application is implementation on the SSL platform and availability through the secure HTTPS protocol. Therefore the data transmitted between users is highly secure.
• Support for system access and versatility: On the web, you are just like a version of the app, except you have a shortcut to the site you are looking for. So you need to have access to phone files and so on to use all the same software features.
• Updates and Updates: Since these types of programs affect the site and may require different sections to be added and updated, they must be kept up-to-date with the features required.
• Offline usage: Some of these web applications work even if they have a weak internet connection or even offline. If you’re careful, both Facebook and Twitter have a lite version that is less than 1 MB in size, though not as a web app but built on the same structure that can be used in the slowest internet connection.

Below is an example of a PWA requesting to add a site to the first page when logging into a site that supports the web app.
