alt Hacker NewsYeah, I know, but since by default the front-end islands are server-rendered with no hydration the lines are blurred between what you would use an .astro component for, and just using for example react.
Personally I only ever use .astro components if I'm 100% sure I will never need any client side interactivity, otherwise it's just easier to ignore them.
I mean, you have to have an .astro file if you want your route to be picked up, and then import and use React components in that file. IIRC, you cannot just directly use React.
