Progressive web apps
Progressive web apps is a term used to describe the modern state of web app development. This involves taking standard websites/apps that enjoy all the best parts of the Web — such as discoverability via search engines, being linkable via URLs, and working across multiple form factors — and supercharging them with modern APIs (such as Service Workers and Push) and features that confer other benefits more commonly attributed to native apps.
These features include being installable, working offline, and being easy to sync with and re-engage the user from the server.
