What is a Progressive Web Application?
A progressive web application (PWA) is a type of web app that combines the best features of both websites and native apps. They're built using web technologies like HTML, CSS, and JavaScript, but offer a user experience similar to a traditional app.
Key features of a Progressive Web Application:
Installability: PWAs can be added to the user's device home screen, similar to a native app, providing a more familiar and convenient experience.
Offline functionality: WAs can work offline or with limited internet connectivity, thanks to service workers that cache essential content and resources
Push notifications: PWAs can send real-time notifications to users, even when the app isn't open, enhancing engagement and keeping users informed.
Full-screen mode: PWAs can be launched in full-screen mode, providing a more immersive and distraction-free experience.
Platform independence: PWAs are built using web technologies (HTML, CSS, JavaScript), making them compatible with various devices and operating systems, including smartphones, tablets, and desktops.
Faster load times: PWAs often load faster than traditional web pages, thanks to caching and optimized performance.
Enhanced user experience: PWAs can offer a more app-like experience with features like app-style navigation, offline capabilities, and push notifications.
Reduced development costs: PWAs can be built and maintained using a single codebase, reducing development and maintenance efforts.
