How to convert "Splash Screen" into a "Captive Portal"?

1

Is it possible?
I wonder if “splash screen” https://tiddlywiki.com/#Creating%20a%20splash%20screen
could be used to control TW entrance.

The idea would be to "interrupt’ loading with a QRCode scanning sequence ( like https://scanapp.org/ ). Checking scanned code through a remote API call whose true/false response decide to continue loading TW.

Do you have any advice or known experiments about it?

One thing I know is the splash screen is removed once the the wiki is fully loaded due to a CSS. It should possibly be best left as a transient splash screen and find another way to achive what you want.

Remember a link to a wiki can include the tiddlername to load, a permalink, even a set of tiddlers and the default tiddlers also chooses what to display on start.

Perhaps you could have a tiddler that loads on startup by what ever method you wish, but one that includes styles, or a class named in the class field, that modify the wikis overall appearance until it is closed.

  • This would include “display: none;” on various elements on the current tiddler and other elements on the page.
  • Some of our CSS experts could possibly do this with their eyes closed :nerd_face:

Another method is to use start-up actions to trigger a modal or window that takes over the whole screen.
