Doesn't work with scripts included from html

[edemaine]

Chrome gives the error: Failed to load module script: Expected a JavaScript module script but the server responded with a MIME type of "text/coffeescript". Strict MIME type checking is enforced for module scripts per HTML spec.

I believe the filename needs to be mapped to .js (or maybe .jsx depending on whether there is JSX? maybe not)... Here is another plugin which does so.

The issue here might actually be that the file is included from an .html file, via <script src="filename.coffee">, not that I was running in dev mode. This plugin does some special handling of HTML to make that work without adding ?transform.

I have the same problem in Development Mode, Firefox gives the error:
Loading module from “http://localhost:5173/main.coffee” was blocked because of a disallowed MIME type (“text/coffeescript”).

The problem no longer persists when built for production.

Thanks for the report and apologies for not replying earlier.

I'm not entirely sure where to start debugging this… Is it a matter of files not being transpiled on time, or is it due to transpiled files not being placed in the correct path?

I looked at the rollup docs and perhaps this plugin may need to grab onto one of the build hooks in order to force a render at a specific time, but I'm not sure if that's the proper way to look at this problem.

I'm a bit tied up with work at the moment, but I'll see if I can take a closer look at this soon,

I suppose that references to vitejs/vite#9963

upd:
and this one vitejs/vite#3828

FWIW, this newer plugin (which uses "unplugin" to work for Vite and lots of other build systems) works much better in this respect (for Civet). Perhaps it could inspire a CoffeeScript plugin? In particular I think the idea is to do transpilation in the load phase. (But see the (short) code for details.)
