[dev] display source mapped line numbers

[mroderick]

I think stale bot might have been a bit too keen to close this issue. I would still very much like to have source maps for my worker scripts

[mroderick]

This would be a very welcome feature 💯

Not using sourcemaps makes working with workers harder than it has to be.

In wrangler dev we should make webpack always generate a sourcemap, serve it with a new local HTTP server and inject a sourceMappingURL in the worker that points locally.

When the worker runtime will load the worker it will send that source map URL to the devtools that it can download from the user endpoint.

@xtuc would we need cloudflared for that to expose the local source map to the public internet?

This would make it also easier to debug exceptions thrown from minified workers 👍🏻

Miniflare seems to have source maps https://miniflare.dev/source-maps.html. And it's now a part of cloudflare.

would love for source maps to be kept when cloudflare minifies the js

Transferred from Wrangler 1 repo to track supporting source-maps for Workers.
