TypeScript ORM for Node.js based on Data Mapper, Unit of Work and Identity Map patterns. Supports MongoDB, MySQL, PostgreSQL and SQLite databases as well as usage with vanilla JavaScript.

import { Entity, OneToOne, PrimaryKey, Property, Rel } from '@mikro-orm/core';
import { MikroORM } from '@mikro-orm/postgresql';

@Entity()

  @OneToOne({ entity: () => Profile, mappedBy: 'rating', primary: true })
  profile!: Profile;

  // eslint-disable-next-line @typescript-eslint/no-inferrable-types
  @Property()
  rating: number = 1000;
