Progressive Web Apps(PWA) Development For Beginners

Progressive Web Apps(PWA) Development For Beginners, Create and publish Progressive Web Apps from scratch.

PWAs are web apps developed using a number of specific technologies and standard patterns to allow them to take advantage of both web and native app features. For example, web apps are more discoverable than native apps; it’s a lot easier and faster to visit a website than to install an application, and you can also share web apps by sending a link.

On the other hand, native apps are better integrated with the operating system and therefore offer a more seamless experience for the users. You can install a native app so that it works offline, and users love tapping their icons to easily access their favorite apps, rather than navigating to it using a browser.

PWAs give us the ability to create web apps that can enjoy these same advantages.

It’s not a brand new concept—such ideas have been revisited many times on the web platform with various approaches in the past. Progressive Enhancement and responsive design already allow us to build mobile-friendly websites.

PWAs, however, provide all this and more without losing any of the existing features that make the web great.

What makes an app a PWA?

There are some key principles a web app should try to observe to be identified as a PWA. It should be:

• Discoverable, so the contents can be found through search engines.
• Installable, so it can be available on the device’s home screen or app launcher.
• Linkable, so you can share it by sending a URL.
• Network independent, so it works offline or with a poor network connection.
• Progressively enhanced, so it’s still usable on a basic level on older browsers, but fully functional on the latest ones.
• Re-engageable, so it’s able to send notifications whenever there’s new content available.
• Responsively designed, so it’s usable on any device with a screen and a browser—mobile phones, tablets, laptops, TVs, refrigerators, etc.
• Secure, so the connections between the user, the app, and your server are secured against any third parties trying to get access to sensitive data.
