I would like to add version for my modules, but i don't know how can I do this. I tried to create a common module.ts but the same name of services killed each us. I tried different module.ts for the versions, it was better but the services with same names didn't work.

This is my last structure:
test-module

• 1.0
  • controllers
    - test.controller.ts
  • services
    - test.service.ts
  • test.module.ts
• 1.1
  • controllers
    - test.controller.ts
  • services
    - test.service.ts
  • test.module.ts

This is my test service(s):

import * as _ from 'lodash';
import { Injectable } from '@nestjs/common';

@Injectable()
export class TestService {
  public test() {
    return '1.0'; // and 1.1 in 1.1 directory
  }
}

This is my module.ts:

import { Module, Logger } from '@nestjs/common';

import { TestModule as DorotTwo } from 'test-module/1.1/test.module';
import { TestModule as DorotOne } from 'test-module/1.0/test.module'

@Module({
  controllers: [ProtobufController],
  providers: [],

  imports: [
    DorotTwo,
    DorotOne,
  ],
})
export class ProjectModule {
  constructor() {
    Logger.log('App initialized');
  }
}

This is a simple test Controller. A tried import TestService from 1.0 or 1.1 but the test function's response is always 1.0.

@Controller()
export class ProtobufController {
  constructor(private readonly testService: TestService) {
    console.log(this.testService.test()); // Always 1.0
  }
.....

If I import the 1.0 and 1.1 services, the TestService in DorotOne overwrite the DorotTwo's Test
service. Is exists an example where I can read how can I create this versioned module?
