PWA
The individual pages and views within a PWA (Progressive Web App) must be linkable via URLs, and each of these must be unique in order to make them easily shareable on social media.
Check that individual pages and views can be opened and visited in new browser windows; moreover, in the case of a single-page app, make it so that the app's state from a given URL can be reconstructed by the client-side router.
