New find: Progressive Web Apps Training, from Google.
“A PWA is not an API or a technology, but it is a web development approach that uses a combination of tools and technologies already available to create targeted, ideal user experiences. [This course] shows how to use service workers, APIs, and an application shell architecture for meaningful offline experiences, fast first load, and easy user reengagement upon repeat visits.”
Two things PWAs can do that a normal web app can’t:
- Send push alerts/notifications.
- Be used offline, and update any changes you made when you are back online.
