Progressive Web App
A website enhanced with service worker caching and an installable manifest, so it opens instantly, survives weak connections, and can sit on a home screen like an app.
Analogy Mental model
Putting a shortcut on someone's home screen instead of asking them to download a hundred megabytes from a store to get the same content.
In practice What you actually do
Worth the effort for high-frequency retail, news, and utility sites. Provide a manifest and register a service worker for caching, but preserve a distinct, crawlable URL for every article and product rather than collapsing the site into a single address.
Where people get burned Pitfalls
A single-page implementation with everything behind one URL is invisible as a set of pages. Each item needs its own address and server-rendered content for search to treat it as a destination.
