sourcemap of import not served/deployed

[declann]

Hi,

Really liking playing around with Framework, congrats on an awesome release!

We might like sourcemaps to go out of fashion(?) but I generate ESM and keep a sourcemap.

I'm importing that ESM using a regular import:

import * as model from './cul/calcs_esm/cul_scope_0.js'

The file ends with //# sourceMappingURL=cul_scope_0.js.map: a reference to the sourcemap file, but because this file isn't deployed (to dist or to observablehq.cloud) or served (with npm run dev), then it isn't available to devtools - see error:

Should/can Framework detect and serve sourcemaps?

On Quarto I include sourcemap files as a resource and they gets served - this could be a workaround, but might need to be a more particular one given Frameworks directory structure (_file, _import etc.)

Thanks!

Declan

Yes we hope to add sourcemaps in the future (see e.g. #805).

Yes, I think it would be reasonable to check for //# sourceMappingURL=… and include the referenced file in dist on build.
