## FAQs

### Circular dependency ⚠️

<details>
  <summary>Click to expand</summary>

[A circular dependency](https://docs.nestjs.com/fundamentals/circular-dependency) might also be caused when using "barrel files"/index.ts files to group imports. Barrel files should be omitted when it comes to module/provider classes. For example, barrel files should not be used when importing files within the same directory as the barrel file, i.e. `cats/cats.controller` should not import `cats` to import the `cats/cats.service` file. For more details please also see [this github issue](https://github.com/nestjs/nest/issues/1181#issuecomment-430197191).
