#6fce33Double-click to submit form pattern with Stimulus (revisited)Some months ago, I wrote about something I built, a component to submit forms with a double-click, where the user has to confirm the action, potentially avoiding miss-clicks and doing something irreve#3adf1e"Double-click to submit" pattern with StimulusWhile tinkering around with a home lab and CasaOS, I encountered this pattern where certain actions require a "double click", like this: I wanted to see how hard it was to copy this with Stimulus, an#a12281Traefik with Kamal: Tips and TricksIt took me some time to finally figure out Traefik and some more time to put two and two together, so I'd like to share some things I learned on how to get it to work smoothly with Kamal.
