Sourcemap with cloudflare-workers project not working

[zbynekwinkler]

What version of Remix are you using?

1.18.0

Are all your remix dependencies & dev-dependencies using the same version?

• Yes

Steps to Reproduce

$ npx create-remix@latest
Need to install the following packages:
  create-remix@1.18.0
Ok to proceed? (y)
npm WARN deprecated @npmcli/move-file@1.1.2: This functionality has been moved to @npmcli/fs
? Where would you like to create your app? ./my-remix-app
? What type of app do you want to create? Just the basics
? Where do you want to deploy? Choose Remix App Server if you're unsure; it's easy to change deployment targets.
Cloudflare Workers
? TypeScript or JavaScript? TypeScript
? Do you want me to run `npm install`? Yes
...
$ cd my-remix-app/
$ npm run dev
Ctrl-C
$ npx source-map-explorer build/index.js
build/index.js
  Your source map refers to generated column 1 on line 3306, but the source only contains 0 column(s) on that line.
  Check that you are using the correct source map.

Expected Behavior

The sourcemap should match.

Actual Behavior

I get the same error with 0.17.0. When I open Javascript debug terminal in vscodium and run npm run dev from there, the debugger attaches. In the Debug diagnostics window I can list all known files but only system node files are there - not a single file from the project.

To fix this we probably want to:

• Remove the build script from the wrangler.toml file in the template (otherwise you're always running production code)
• Ship sourcemaps with Remix packages OR change the CF templates to not require bundling dependencies

Should be fixed by #7574
