importing files directly outside of the index

[rosskevin]

Hey, thanks for sharing this!

I'm transitioning some internal repos and having some problems with imports, namely

src/main.ts(3,17): error TS2307: Cannot find module '@quramy/x-core/foo'.

PR with changes/demo: https://github.com/Quramy/lerna-yarn-workspaces-example/pull/5/files

What am I missing here? It's got to be simple but I have yet to spot it.

Any thoughts?

Figured it out and pushed change to PR for anyone that finds this. To support this and the index use case, you need to manually list each package path in addition to the general wildcard:

{
  "extends": "./tsconfig.base.json",
  "compilerOptions": {
    "baseUrl": "./packages",
    "paths": {
      "@quramy/x-core/*": ["./x-core/src/*"],
      "@quramy/*": ["./*/src"]
    }
  }
}

Anyone knows how to link local dependencies in development?

when I execute node packages/x-cli/lib/main.js,

I got Error: Cannot find module '@quramy/x-core/foo/bar'
