jsaddle-warp - Always render jsaddle page regardless of url (for client side routing) about jsaddle

[ryantrinkle]

It does replace with the dynamically generated one. It's careful to make sure the switchover is instantaneous, but it does not make any attempt to reuse existing elements. What we've done in the past is disable all input elements on the page using runInputDisabledT when drawing the page statically, so that the user can't start entering information until the JS loads.

It would be great if we could take over the DOM instead, but it would take some work to get there.

Hm, apparently I didn't commit that experiment to our project, but I can recreate it when I get to my own notebook where stuff is properly set up.

1. Basically i created an app along the lines of main = run 8081 $ mainWidget $ el "input" blank
2. compile it with ghcjs
3. in the resulting, generated html add an <input> with an initial value / content
4. run the app
5. the initial value should be gone / overwritten by the starting app

What I wanted to test was, that if the app is send with statically pre-generated html, people start typing in the input-field (or textarea) and then the javascript finishes bootin and kicks in, that whatever people wrote isn't lost. Thus I wanted to check, whether the renderer merges changes over existing DOM or just replaces it with the dynamically generated one.

It was just a quick experiment though (I edited the generated html!) and I just might not have stumbled across a way to get this inflation to work properly.

Though this is actually I different issue. Should I repost it as such? (propbably rather to reflex-frp/reflex-dom though, as -- i guess -- it's not directly a thing that jsaddle needs to / should resolve)

e.g. if the SPA uses "/", "/new", "/post/<postId>" it would be nice to reload the page on any of these and continue debugging.
(our current work-around is to use fragment-identifiers; however, should reflex-dom implement static-prerendering javascript-less navigation becomes a possibility and fragment-identifiers are rather suboptial for that)

@m0ru Agreed!

Also, you might be pleasantly surprised to learn that reflex-dom has supported static rendering for quite some time.

[pheara]

ah, yes, i forgot ^^"
afair we tried it while setting up the project but ran into problems when inflating it on the client (using the static rendering as pre-render to speed up page-loading)

[ryantrinkle]

@m0ru Ah, interesting. I'd love to know what you ran into - maybe it's stuff we can fix!
