*** DONE in template range over enabled providers to create buttons for each
*** DONE make dialog show on click of some element

** TODO i guess i would also like to send htmx event for reloading the page
** DONE i guess i would also like to send htmx event for reloading the page
on successful auth?
now, why would logout work, and login not work?
eh, let's go back on body doing the hx-get on event?
maybe this is because of open dialog
*** wait, maybe then returning from other auth middlewares will work
no.
for some reason
#+begin_src go
e.HttpContext.Response().Header().Add("HX-Trigger", "auth-change-event")
#+end_src
this header when returned with response to request triggered by js, doesn't result in event being triggered,
ok, i guess
*** so yeah, uglier that i wanted
wanted to have hx-get="/" hx-trigger="auth-change-event"
and send these events from all auth middleware methods
https://htmx.org/docs/#response-headers
but on auth success, even though header is present in the response, no event is triggered
( checked with event listener in console )
so, yup. coupling between js code of oauth, middlewares and body tag. this seems like too much.
but it somewhat works
** TODO add one more page that checks auth
and let's use existing middleware from framework documentation
** TODO add tailwind styling
** TODO package static into single binary
** TODO write nix build
