What are Progressive Web Apps?
Simply defined, Progressive Web Apps are like lightweight websites that behave like an app by combining the best features of native environments with web technologies. Progressive Web Apps development comprises of the following three elements:
Website: Progressive web apps are written in HTML, CSS, and JavaScript, but mainly use JavaScript for interactivity. This means they don’t require a development environment and are supported by all current browsers.
Web manifest: Progressive web apps have a JSON file containing details like the name, the icon, description and access-related info. This JSON file takes care of communicating with the mobile device or the browser that what they have is not a regular website but a progressive web app.
Service worker: This is essentially a JavaScript that runs in the background independent of the progressive web app and forms the technical foundation for functionalities like push notifications, rich offline experiences, background syncs etc.
