Nested Module Resolution?

I’m trying to figure out how to get nested module resolution working with this project.

What I mean is modifying the structure to a more real-world example with multiple nested modules, in a domain driven architecture where all our exports are in a domain and referenced by e.g. import { sleep } from '@quramy/x-core/messages/core'

Structure:

- x-cli
-- src
--- main.ts
- x-core
-- src
--- messages
---- core
----- sleep
------ sleep.ts
------ sleep-and-snore.ts
------ index.ts
----- wake
------ wake.ts
------ wake-and-eat.ts
------ index.ts (exports wake and wake-and-eat)

I have modified /tsconfig.json: and then updated main.ts:

{
  "extends": "./tsconfig.base.json",
  "compilerOptions": {
    "baseUrl": "./packages",
    "paths": {
      "@quramy/x-core/messages/*": ["./x-core/src/messages/*"],
      "@quramy/*": ["./*/src"]
    }
  }
}
// main.ts (this works fine in the IDE, just doesn't build...)
import { sleep, sleepAndSnore } from '@quramy/x-core/messages/core'

export function cli() {
  sleep();
  sleepAndSnore()
  return Promise.resolve(true);
}
cli()

yarn prepare then gives me this error: src/main.ts(1,38): error TS2307: Cannot find module ‘@quramy/x-core/messages/core’.

If I add the paths/baseUrl to the tsconfig.build.json, it will build, but it doesn’t run because it can’t find the module.

I also get the "source files not under the same rootDir message if I have that compilerOption set under this case: TS6059: File '/home/bthompson/source/lerna-yarn-workspaces-example/packages/x-core/src/messages/core/index.ts' is not under 'rootDir' '/home/bthompson/source/lerna-yarn-workspaces-example/packages/x-cli/src'. 'rootDir' is expected to contain all source files.

Any help would be greatly appreciated!

If I add the paths/baseUrl to the tsconfig.build.json, it will build, but it doesn’t run because it can’t find the module.

I solved this by using module-alias package.

import { addAlias } from 'module-alias';
import { join } from 'path';

if (process.env.NODE_ENV === 'development') {
  addAlias('@scope/common',  join(__dirname, '../../common/build'));
}
