Progressive Web Applications

Progressive web applications are those apps which take advantage of modern browser features to make it easy to be added on homescreens, behaving just like the native applications. These applications are the same as normal websites in that they are made of CSS, HTML and JavaScript. They also live in the browser. They are:
i) Reliable: This is because they load instantly even when there is network uncertainty.
ii) Fast: They respond quickly to user interactions with very smooth animations, even without users scrolling much.
iii) They are quite engaging: They feel like a natural app on your device, giving you an engaging user experience.
About Progressive

What makes them different from the normal websites?

1. They are very safe
Most of these apps work with technologies that deal with sensitive data that requires to be handled with lots of caution. This makes them very safe. For this reason, progressive web applications have to be served through an HTTPS connection. Users who do not have access to a server with a SSL certificate and want to run their projects in a secure environment can only do this through GitHub pages or a similar service. This is because any GitHub repository can be hosted directly over https and both GitHub pages and GitHub are free for public repository. This safety helps a lot in ensuring that there is no snooping and that the content has not been interfered with.

2. They are connectivity independent
Key Feature of PWA
This is very important as it ensures that the app is able to work even when there is no network connection. There are those that have been cached differently and this means that their UI is available offline, though their dynamic content will still need access to the server. There are those others that are cached entirely and this means that all their source code and resources will be saved locally so that the app can work offline and online at the same time. This is possible because these apps have been enhanced with service workers for them to work better even on low-quality networks.

3. They are progressive
This means that progressive web applications use web technologies that are supported widely and those that work very well on multiple web browsers. This is not something that is easy to achieve in the world of web development, though there is a lot that can done to ensure that developers are covering a larger user base. This helps a lot in order to ensure that a lot more people are able to use the app, since different people use different browsers and platforms to access the web. These types of apps are built with enhancement as their core principle to be useful to every user, regardless of their browser choice.

4. They are installable

Any website by default can be saved manually on the home screen for instance through use of the Add to Home Screen button though it can be hard for some apps.
