New Entity Creation for Backend Use only

[aldisa]

I would like to create a new Entity called: EntityA
which is located in a custom module which is called: MyModule.

All MyModule code is located inside:

<espo-root>/custom/Espo/Modules/MyModule

I have created the following files inside the Module folder specified above:

File: Resources/metadata/scopes/EntityA.json

{
  "entity": true,
  "layouts": false,
  "tab": false,
  "module": "MyModule"
}​ 

Does it need anything else specified in scopes?

File: Resources/metadata/entityDefs/EntityA.json

{
  "fields": {
    /** define all fields with types etc here **/
​  },
  "indexes": {
    /** define db indexes here **/
​  }
} 

Is anything else required here?
Does it need language definitions in Resources/i18n/<lang>/EntityA.json if no usage in Frontend (UI)?

Controllers/EntityA.php
Entities/EntityA.php
Repositories/EntityA.php

Is it required to define any of the following class definition files which solely extend from Core Classes, if the only usage will be CRUD operations through the EntityManager Class?

No need for:

• Controller
• Language
• Repository (not needed in 99% cases)
• metadata/clientDefs
