Progressive Web Apps (PWAs) combine the capabilities of a native app and the reach of a web application. Today, we will introduce PWAs and build a basic, offline web application.

Progressive Web Apps (PWAs) could be the next big thing for modern mobile app development. This powerful tool combines the capabilities of a native app and the reach of a web application. They use modern APIs to deliver reliability and installability, while reaching anyone, anywhere, on any device with a single codebase. PWAs are on the rise for web development, and companies large and small are taking advantage of this powerful technology. Today, I want to introduce you to PWAs and get you started with a basic application.

We will go over:

• What is a PWA?
• Fundamentals of PWAs
• Create a PWA from scratch
• What to learn next

What is a PWA?

Progressive Web Apps (PWAs) are web applications that use modern technologies to provide a user experience that closely mimics a native app. PWAs have become very popular in recent years as they do not only improve performance and user experience but are also accessible when a user is offline.

The primary goal of a PWA is to provide the same experience as a native app using a majority of the features available to mobile app developers. PWAs combine the best of mobile and web apps into one technology. You can essentially build a website using front-end web technologies, but it acts, feels, and behaves like a mobile app.

This modern solution to app development makes it easy for mobile app developers to get their products to market without going through the slow validation progress of Apple or Play stores. Once a PWA is deployed, it is immediately available to users. This also means that users don’t have to manually update apps to get the latest person: it is automatically deployed.

The development costs for PWAs are notably cheaper than native apps, as it eradicates the need for both an iOS and Android team. This valuable modern solution to app development leverages a larger web ecosystem for maintaining apps compares to native apps. Progressive Web Apps clearly have a lot of benefits. Let’s take a look at some of their characteristics.

• Progressive: A PWA must work on every device and enhance progressively, meaning that the features available to a user’s device or browser are accounted for.
• Discoverable: A progressive web app is essentially a website, so it must be discoverable on search engines.
• Offline capabilities: A PWA should work when the user is offline. It should also work in areas of poor or low connectivity.
• App-like:. PWAs should behave and look like a native app.
• Linkable: PWAs are essentially websites, so they should use the URI to indicate the application’s state so that the app can retain its state.
