Local Dev Only Seems to Support Projects Created in \sfdx-source\main\default

[supert3d]

Summary

Local Dev only appears to support LWC components created in the OOTB directory \sfdx-source\main\default our project uses a custom directory \sfdx-source\[customNamespace]\[directories]

Steps To Reproduce:

• Run through all prerequisites here https://developer.salesforce.com/docs/platform/lwc/guide/get-started-test-components.html
• Execute sf lightning dev app in Terminal.

Expected Result

• Browser loads
• Able to live preview site

Actual Result

• Browser loads
• LWC changes made aren't reflected live.
• Errors with Error (1): Expected workspace to have one lwc folder

Additional Information

If I DEBUG=* sf lightning dev app I get additional debug and can see Skipping [redacted]\sfdx-source\main\default because it does not exist or is not a directory which is correct I don't have this directory; we're using a custom directory.

Then it errors with
Error (1): Expected workspace to have one lwc folder

@supert3d Thanks for filing the issue. Can you please attach the contents of sfdx-project.json to the issue description?

The reported issue appears to be similar to #185

@supert3d , From my understanding ( Just as someone who peeked at the source this afternoon ), you may have to have a path ending in "lwc" if you choose not to confine by the OOTB path determined. Check out this line of code when creating the LWC Server:

plugin-lightning-dev/src/lwc-dev-server/index.ts

Line 33 in b9ca5a2

const namespacePaths = (await Promise.all(packageDirs.map((dir) => glob(`${dir.fullPath}/**/lwc`)))).flat();

So your directory structure would have to look something like:

- myCustomPackage/
  - lwc/
    - myComponent/
      - myComponent.js
      - myComponent.html

Also worth noting that your sfdx-project.json would have to define your custom directory

{
  "packageDirectories": [
    {
      "path": "force-app",
      "default": true
    },
    {
      "path": "myCustomPackage",
      "default": false
    }
  ],
  "namespace": "",
  "sfdcLoginUrl": "https://login.salesforce.com",
  "sourceApiVersion": "57.0"
}
