How can I add a custom built-in entity to a JHipster blueprint without using JDL?

[sacaaa]

I'm creating a custom JHipster blueprint, and I want to include a custom built-in entity (for example, UserSettings) that should be generated automatically during the app generation process — similar to how JHipster includes the User or Authority entities by default.

The key point is that I don't want to define this entity using JDL. Instead, I want to programmatically inject it into the generation process as part of the blueprint logic, so the user doesn't need to explicitly create or import it.

I'm looking for a proper way to:

• Inject and generate a custom built-in entity (e.g., UserSettings) as part of a blueprint, without JDL.
• Ensure it's treated like a real .jhipster entity with all code generated (backend + frontend).

The easiest way is to create a real entity in .jhipster folder:

  get [BaseApplicationGenerator.CONFIGURING]() {
    return this.asConfiguringTaskGroup({
      createCustomEntity() {
        const entityName = `CustomEntity`;
        const entityStorage = this.createStorage(`.jhipster/${entityName}.json`);
        entityStorage.set({
          name: entityName,
          fields: [],
          relationships: [],
        });
        this.jhipsterConfig.entities = [...this.jhipsterConfig.entities, entityName];
      },
    });
  }
