Issues with yarn workspaces / monorepo

[apss-pohl]

Describe the bug

I am currently trying to implement an existing monorepo structure which makes use of yarn workspaces to your bundler because i think you really did an awsome job here! Big praise!

For testing purpose i created a reduced repository:
https://github.com/apss-pohl/nestjs-test/tree/feat/ev

There are some issues i am currently facing:

• i don't get any console or application logs
  -- e.g. https://github.com/apss-pohl/nestjs-test/blob/feat/ev/apps/main/src/main.ts#L47)
  -- other nestjs output

- the renderer cant be changed, i have to provide src/renderer
https://github.com/apss-pohl/nestjs-test/blob/feat/ev/apps/main/src/main.ts#L53

index.html file is not found in /src/renderer directory
dep-3b8eb186.js:12907
error during start dev server and electron app:
Error: build rollupOptions input field required for the electron vite renderer config

UPDATE/ RESOLVED: Overlooked the note here: https://electron-vite.org/guide/dev.html#customizing

• something is off with the bundling, the external packages cannot be found (biggest issue)

App threw an error during load
main.js:124
Error: Cannot find module '@nestjs/websockets/socket-module'

I played a lot with the externalization of those but i dont get it working (this did the trick in my current bundler):
https://github.com/apss-pohl/nestjs-test/blob/feat/ev/electron.vite.config.ts#L36
If i don't add those to the list of external i get following output:

"class-transformer/storage" is imported by "class-transformer/storage?commonjs-external", but could not be resolved – treating it as an external dependency.

Any advice highly appreciated

I also created a branch with nestjs but without the workspaces:
https://github.com/apss-pohl/nestjs-test/tree/feat/ev_plain
This is working as expected (First two point are the same)

Bad config https://github.com/apss-pohl/nestjs-test/blob/feat/ev/electron.vite.config.ts

Simple way:

export default defineConfig({
  main: {
    plugins: [externalizeDepsPlugin(), swcPlugin()],
    build: {
      rollupOptions: {
        input: {
          index: resolve(__dirname, 'apps/main/index.ts')
        }
      }
    }
  },
  preload: {
    plugins: [externalizeDepsPlugin()],
    build: {
      rollupOptions: {
        input: {
          index: resolve(__dirname, 'apps/preload/index.ts')
        }
      }
    }
  },
  renderer: {
    root: './apps/renderer'
    build: {
      rollupOptions: {
        input: {
          resolve(__dirname, 'apps/renderer/index.html')
        }
      }
    }
  }
}

Hello,
thank you for your reply. I changed the configuration following your recommendations: https://github.com/apss-pohl/nestjs-test/blob/feat/ev/electron.vite.config.ts
But it makes no difference (The issue mentioned with the renderer was already fixed).
I was also reading the dependencies section carefully again but i cant get it up and running. I picked '@nestjs/websockets/socket-module' as example because it is the first one breaking. I literaly treid every combination: Configured it as external dependecy within your plugin, excluded it, included it, configured it external within rollup section. And also as manual chunk:

I think the bundling gets confused with the workspaces. It does work with this very simple config and workspaces removed, no special dependency configuration needed at all (but has the same depedencies):

Yarn 3, add configuration in the .yarnrc as follows:

nodeLinker: "node-modules"

Yarn 3, add configuration in the .yarnrc as follows:

nodeLinker: "node-modules"

This is already the case: https://github.com/apss-pohl/nestjs-test/blob/feat/ev/.yarnrc.yml

I cant get past this. Is there any other idea what i can try?
