Imports of apps are forbidden (nx-enforce-module-boundaries)

Expected Behavior

I am importing a class from a Common workspace (library) and I should not have any linting errors.

Current Behavior

I am importing a class from a Common workspace (library), and the linting is throwing an imports of apps are forbidden (nx-enforce-module-boundaries).

Steps to Reproduce

I have a a Common workspace described as follows in angular.json:

    "feature-api-common": {
      "root": "libs/feature/api/common",
      "sourceRoot": "libs/feature/api/common/src",
      "projectType": "library",
      "schematics": {},
      "architect": {
        "lint": {
          "builder": "@angular-devkit/build-angular:tslint",
          "options": {
            "tsConfig": ["libs/feature/api/common/tsconfig.lib.json", "libs/feature/api/common/tsconfig.spec.json"],
            "exclude": ["**/node_modules/**", "!libs/feature/api/common/**"]
          }
        },
        "test": {
          "builder": "@nrwl/jest:jest",
          "options": {
            "jestConfig": "libs/feature/api/common/jest.config.js",
            "tsConfig": "libs/feature/api/common/tsconfig.spec.json",
            "passWithNoTests": true
          }
        }
      }
    }

with the following tags from nx.json:

    "feature-api-common": {
      "tags": ["shared"]
    }

This workspace doesn’t have a Nest module. I have a base entity with some date types, that I want to import. The entity is exported in an index.ts file, and then the path is as such in tsconfig.json:

"@team-management/api/common": ["libs/feature/api/common/src/index.ts"]

I have a different workspace, with a Nest module. In this module, I have an entity that I want to inherit from the common dated entity, as such:

import { DatedEntity } from '@team-management/api/common';
import { Column, Entity } from 'typeorm';

@Entity('exercise')
export class ExerciseEntity extends DatedEntity {
   ...
}

but it throws the imports of apps are forbidden (nx-enforce-module-boundaries) error.

This exercise workspace is described in the angular.json:

    "feature-api-exercises": {
      "root": "libs/feature/api/exercises",
      "sourceRoot": "libs/feature/api/exercises/src",
      "projectType": "library",
      "schematics": {},
      "architect": {
        "lint": {
          "builder": "@angular-devkit/build-angular:tslint",
          "options": {
            "tsConfig": [
              "libs/feature/api/exercises/tsconfig.lib.json",
              "libs/feature/api/exercises/tsconfig.spec.json"
            ],
            "exclude": ["**/node_modules/**", "!libs/feature/api/exercises/**"]
          }
        },
        "test": {
          "builder": "@nrwl/jest:jest",
          "options": {
            "jestConfig": "libs/feature/api/exercises/jest.config.js",
            "tsConfig": "libs/feature/api/exercises/tsconfig.spec.json",
            "passWithNoTests": true
          }
        }
      }
    }

with the following tags in nx.json:

    "feature-api-exercises": {
      "tags": ["feature:api", "backend"]
    }

and these are my rules for nx-enforce-module-boundaries in tslint.json:

    "nx-enforce-module-boundaries": [
      true,
      {
        "enforceBuildableLibDependency": true,
        "allow": [],
        "depConstraints": [
          {
            "sourceTag": "app",
            "onlyDependOnLibsWithTags": ["shared", "feature:shared"]
          },
          {
            "sourceTag": "shared",
            "onlyDependOnLibsWithTags": ["shared"]
          },
          {
            "sourceTag": "feature:lazy",
            "onlyDependOnLibsWithTags": ["shared", "feature:shared", "feature:api"]
          },
          {
            "sourceTag": "feature:api",
            "onlyDependOnLibsWithTags": ["feature:api", "shared"]
          },
          {
            "sourceTag": "feature:shared",
            "onlyDependOnLibsWithTags": ["shared", "feature:api"]
          }
        ]
      }
    ]

As a comment, I can import this entity without linting error in a workspace with the tag app.

Am I doing something wrong, like adding tags where I shouldn’t, or the Common workspace without a module shouldn’t be declared in angluar.json? Could it be a version error?

AFAIK, @team-management/api/common is an invalid package name. You can only have @<scope>/<name> and not any nesting like @<scope>/api/common/legacy/core/state.

It seems because I have an application named api it was causing some kind of conflict or misdirection. Changing the tsconfig.json path from:

"@team-management/api/common": ["libs/feature/api/common/src/index.ts"]

to

"@team-management-api/common": ["libs/feature/api/common/src/index.ts"]

solved it.

Thanks for the guidance.
