A Progressive Web Application, or PWA, is a type of web app that feels more like a traditional mobile or desktop app. One of its main characteristics is that it works directly through a web browser, so users do not always need to download it from an app store. PWAs are also designed to be responsive, which means they adjust well to different screen sizes, such as phones, tablets, and computers. They are usually fast, easy to access, and can often be added to the home screen like a regular app.
Another important characteristic of a PWA is that it can work even with a weak internet connection, and sometimes even offline, by using stored data. PWAs can also send push notifications, load quickly, and update automatically when new content is available. They are built to be reliable, secure, and user-friendly, giving people a smooth experience similar to using a native app while still being available through the web.
