Progressive Web Apps (PWA) reap the benefits of new technologies to bring users the finest of mobile sites & native applications. They are reliable, fast, and engaging. They stem from a secure source and load regardless of the network state.

What is a Progressive Web App (PWA)?

Progressive Web App is not a new framework or technology. It’s a set of best practices to create a web application similar to a desktop or mobile application. The plan is to have such a uniform and seamless experience that the user cannot tell the difference between a Progressive Web App and a native mobile app. It offers user experience via progressive enhancement. It actually implies that a PWA will perform the same operations on a new iPhone 8 as on an older generation iPhone. Although certain features may not be present, the app will continue to work and perform as it should.



Why do we need PWAs?

Progressive web apps take advantages of latest web development frameworks and tools. There are multiple reasons why we need them today, but here are a few of the top facilities it provides:

Mobile User Experience :

PWAs feel and act like native applications. They sit in the home screen of a user, send push notifications like native applications, and have access to the functionalities of a device like native apps. The experience is streamlined and integrated.

Fast Features :

PWAs provide consistently fast experiences. Everything takes place really quickly from the time a user downloads an app to the time they begin interacting with it. Since you can cache the data, restarting the app is incredibly quick, even without hitting the network.

Engaging Audience :

Since we can send notifications to a customer, we can really fuel the engagement by keeping the user notified and engaged with the app.

Dependable Experience :

With the help of service staff, even when the network has failed, we can reliably paint an image on a user’s screen.

Create PWA with ReactJS :

Getting the app was just that easy! But it’s not even the best part. When you open this app, you’ll be able to browse the content even if you don’t have internet. You have access to the app offline! What you’ve encountered is a Progressive Web App (PWA). It allows you to install the application from the browser window itself, is accessible as a native app on your mobile, and works offline, just like a native app. Progressive web apps are a hybrid of regular web pages (or websites) and a mobile application.

How to Build a Progressive Web App Using React JS

We will explain here four minimum requirements for building progressive web apps using React JS:

Web App Manifest :

To make your application installable, you must include a manifest.json in the root directory of the application. You can think of it as a description of your request, similar to what you could submit to the App Store. It contains icons, a splash screen, a name and a description. We can write this manifest file ourselves or we can use tools to create one for us.

Register a Service Worker :

Service workers are event-driven employees who work in the background of an application and behave as a proxy between the network and the application. They are able to intercept background network requests and cache information for us. This can be used to store data for offline usage. They are a javascript script that listens to activities like fetch and installs and executes tasks.

Icons Items :

This is used when a user installs the PWA in their application drawer to provide an app icon. A jpeg image is just going to be fine. The manifest tool helps to generate icons for various formats, and are very helpful.

Served Over HTTPS :

In order to be a PWA, the React JS web application must be served over a secure network. Being a safe site is not only a best practice, but it also defines your web application as a trusted site for users showing trust and reliability and avoiding middle-man attacks. SSL provides an additional layer of security to the web, helping your consumers feel safe when using your site. HTTPS is crucial for using service workers with PWAs and enabling home screen installation. You can buy an SSL certificate from your domain registrar at a little cost and then configure it through your hosting service.

Analyze App’s Performance

Performance is PWAs’ heart and soul. Your app should be speedy on all network conditions for customers. Caching and offline functionality helps a lot, but your application should be fast at the end of the day, even if the user does not have the browser to help service worker technology. This is the definition of progressive enhancement–providing everyone with a positive experience, regardless of device modernity or network conditions.

Final Words :

More and more companies are now exploring the idea of using PWAs. Especially for start-ups and businesses that don’t already have a native app, this is the right time for you to explore PWAs and improve the way in which customers interact with your company online.  Feel free to contact us for more information.
