A Progressive Web App (PWA) is basically a hybrid of a web page and a mobile application. PWAs run on top of a script called a service worker that allows them to run like a regular app without the burden of a ton of code to slow it down. Since they do not rely on as much underlying code, PWAs are much smaller than their native app counterparts. Downloads are incredibly fast. The app can be downloaded almost the very moment you hit the button, and unlike a website, it doesn’t matter how fast or slow the connection is, the app will load instantly, even allowing for offline use and submission of data. Once the network connection is re-established, the data will automatically be sent. You can also use the built-in features of your phone when using the app, such as Camera and Location Services.
PWAs make every step in development faster with simple drag-and-drop functionality but also have additional options for further development if desired, such as integration with other software programs like databases, as well as the ability to add design features by adding CSS. You can build and deploy an app in minutes. The app installs on your smartphone or tablet (iPhone or Android) and looks just like the rest of your apps.
You don’t have to go through the App Store or Google Play process, just share the App URL (for the Public to use or only for your staff to use). You don’t have to compile code, and updates are dynamic and can be completed with ease in real time.
Unlike most native apps, PWAs work across platforms (iOS, Android), so you only have to build an app once. That makes it significantly easier to keep track of as opposed to traditional development. You do not have to worry about the different bugs you would normally find in testing for the iOS and Android versions.
Examples of PWAs
- Trivago
- Uber
