vite auto-refresh

[manzt]

Normally vite handles a request for index.html, but vite-plugin-virtual-html-template intercepts requests for .html and doesn't allow vite to inject a runtime client to handle auto-refreshing.

This PR adds a minimal plugin to inject the /@vite/client code during dev and force and auto-refresh. It's not perfect, but it's better than the existing solution.

Thanks for the PR! I wonder, does Vite not like the template approach? Maybe we should restructure the examples to have better support by Vite? Right now it feels like we replaced a stable working dev setup with a fast but brittle solution. Don't get me wrong, I like the speediness of Vite but with Webpack everything just worked without any special setups.

Unfortunately, I don't have much experience with Vite but I'll poke around a little tonight.

Yeah this is the primary "issue". Vite out of the box assumes 1:1 mapping of files on disk to your app entry points. Plugins can help with some of this, but plugin ecosystem is young.

I thought about this as well, but the issue is that we really do want a template of some type for the examples. Making vite (without any plugins) work nicely would entail creating separate x.html.

Have a look at my latest changes and let me know what you think. I don't mind reverting if that is your preference!

Hmm really odd error in the CI. I tried to track I down earlier to no avail..
