I’m a Newbie Backend Developer of Nodejs

I Have questions when using Backend Programming with nestjs and prisma

Most of books, lectures(videos), people related to programming says “Business logic should be placed on the entity” but prisma’s model generate interface

Then How can i write business logic on entity? it’s not Class

When i use typeorm, entity is class. and i write business logic on entity class

There are my thoughts

1

use implments with prisma’s type

export default class Tag extends BaseEntity implements tags {
  constructor(data: Tag) {
    super();
    this.id = data.id;
    this.name = data.name;
  }

  id: number;
  name: string;
}

but it’s not best way, cuz if when i use another orm, i need to modify all entities
i think it’s anti pattern

I need to advice of backend programming

Please share your advice on the matter
