Have your back end represent a given resource as microformatted-semantic markup, send it gzipped over the wire, and you've got the data exchange you need, even if your mobile app isn't already dressed-up webview.

Are you still referring to dedicated API routes, or are you talking about annotating your UI to the point where it can serve as the API as well? I remember the latter being the vision behind things like RDFa, but those approaches never took off, for a variety of reasons.

At that point you might as well serve XML and use an XSLT transform (+ CSS) to render the view on the client (yes, this is still possible without JavaScript).

When you request a page, it is render on the server and all of the HTML is returned over HTTP as usual. After the client has received the HTML updates, live updates can go over a websocket. For instance you start typing in a searc…

> You just do LiveView instead of a regular controller. No duplication. Yes but this is only in the happy case when the client is fully enhanced no? What happens if you hook up a phx click event to increment a like counter. After the page is loaded, if you click the + to increment it while having JavaScript disabled it's not going to do anything right? But with Hotwire Turbo, if you have a degraded client with no JS,…

Yes, the `phx-click` doesn't automatically get translated to a link or form submission. You can still design the page to work without javascript. For instance by having a "+" button be a normal form or link and then have phx-click intercept it when javascript is enabled. This can be done with one LiveView module without having to also have a separate regular controller.

One way to do it would be to in the `mount` function handle normal non-javascript params being sent and a `handle_event` function handle `phx-click`.

I don't know if there is already a way to have `phx-click` with fallback to HTTP in a less "manual" way. It should be possible to make.

Spoiler, it's just Ajax but it pushes the data through your templates before sending it to the client. We were doing this literally over a decade ago in the early days of XHR.

Isn't the point that it's a framework to accomplish this, rather than "look what we can do!"?
