Answer 1

Would something like this help?

import { Prop, Schema, SchemaFactory } from "@nestjs/mongoose";

export type UserDocument = User & Document;

// Any key as string, and value as a number.
export interface CustomData {
  [key: string]: number;
}

@Schema()
export class User {
  @Prop()
  name: string;

  @Prop()
  age: number;

  @Prop({ type: [Object] })
  customData: CustomData[];
}

export const UserSchema = SchemaFactory.createForClass(User);
