document.addEventListener('alpine:init', () => { Alpine.data('video', () => ({ 'show_video': false, ...

That way there's code highlighting and syntax checking for JS.

I definitely go this route for Alpine about half the time.

PyCharm doesn't seem to have one (I hope I'm wrong). That being said, it is possible to put the code into a proper <script> block. I personally only a trivial amount of code in html attributes such as checking a boolean value with `x-show`.
