PostHTML and HMR

[alexanderbluhm]

I successfully set up a PostHTML compile for the index.html page using transformIndexHtml.
However, I want to use PostHTML in all .html files. I tried the transform plugin function but it only lists js files and not my html components.

In addition, I want to recompile the index.html file is one of my html components changed. Vite is recognizing a change of the component file but I don't know how to trigger the rebuild of the index file. The docs are very sparse here and don't have any examples.

So does someone has an idea how to use PostHTML in all .html files and rebuild the index file with HMR?
Thanks in advance! :)

I could solve the issue with the help of a nice Discord community member.
First, I've understand that transformIndexHtml is only index.html but it is in fact the file which is opened in the browser, so any html file.
So, PostHTML also works in other html files.
In addition, I could set up HMR by implementing a plugin with the handleHotUpdate function.
In this I checked the file type and used server.ws.send({ type: "full-reload" }); to reload the current html file.

Looking forward to the plugin!
