question: `@Expose` decorator with `toClassOnly` in not working as expected

[AdamBialobrzewskiTR]

I have that class.

Article {
    @Expose({ name: "_id", toClassOnly: true })
    private id: string;
}

In comming Json:

{
  "_id":"asdasdas"
}

I have _id, but I have to return in response Json id, like

{
  "id":"asdsdads"
}

Function: classToPlain(article) returns that json:

{
  "_id":"asdasdas"
}

but when I view variable article, structure are correct.

Why function classToPlain ignoring @Expose({ name: "_id", toClassOnly: true })

Have you tried :

class Article {
    @Expose({ name: "_id", toClassOnly: true })
    @Expose({ name: "id", toPlainOnly: true })
    private id: string;
}

@Roms1383 answer works, but you can just also omit the toClassOnly option.

import 'reflect-metadata';
import { Exclude } from './decorators';
import { classToPlain, plainToClass, Expose } from './index';

@Exclude()
class Article {
  @Expose({ name: '_id' })
  public id!: string;
}

const instance = plainToClass(Article, { _id: '1234' });
const plain = classToPlain(instance);

console.log(instance); // logs Article { id: '1234' }
console.log(plain); // logs { _id: '1234' }
