This package is enable you to create files for layered architecture like usecase, query, repository and so on when developing Angular application.
Files made by this package have same construction as service which is made by ng generate service, so they are injectable by any components or classes.
This package is made with Schmatics.

if you use yarn

yarn add @angular-devkit/schematics-cli -D
yarn add ng-layer-generator -D

if you use npm

npm i @angular-devkit/schematics-cli -g
npm i ng-layer-generator --save-dev -g

yarn ng-lg

or

ng-lg

then start interpreter

Please enter a name: sample
Please enter a type name(ex: repository, usecase, query and so on): usecase
Please enter a path name(where to generate file): usecases
Please enter a project name(which project to generate file): (not necessary)

then, /src/app/usecases/sample.usecase.spec.ts and /src/app/usecases/sample.usecase.ts are created.

file's contents are as follows.

// /src/app/usecases/sample.usecase.ts
import { Injectable } from '@angular/core';

@Injectable({
  providedIn: 'root',
})
export class SampleUsecase {
  constructor() {}
}

// /src/app/usecases/sample.usecase.spec.ts
import { TestBed } from '@angular/core/testing';

import { SampleUsecase } from './sample.usecase';

describe('SampleUsecase', () => {
  beforeEach(() => TestBed.configureTestingModule({}));

  it('should be created', () => {
    const type: SampleUsecase = TestBed.get(SampleUsecase);
    expect(type).toBeTruthy();
  });
});
