Read-only properties

[frbuceta]

Is the property readOnly in loopback 4? I've been looking for a while but I have not found anything about it

type: object
properties:
  id:
    # Returned by GET, not used in POST/PUT/PATCH
    type: integer
    readOnly: true
  username:
    type: string
  password:
    # Used in POST/PUT/PATCH, not returned by GET
    type: string
    writeOnly: true

Since a model property is essentially a TypeScript class property, can you try defining it with readonly keyword like https://www.tutorialsteacher.com/typescript/typescript-readonly?

@model 
class User {
  @property({
    type: 'string',
    id: true,
  })
  readonly id: string;

}

This does not work for me

  @property({
    type: 'string',
    id: true,
    required: true,
    default: () => {
      return uuid()
    }
  })
  readonly uuid: string;

Can somebody help me?

AFAIK, LoopBack 4 does not support readonly properties yet.
