TypeORM is an ORM (Object-Relational Mapping) library for Node.js and TypeScript that simplifies working with databases by allowing you to work with tables as objects.
In my experience using TypeORM:
- I created entities using decorators, which allow describing the table structure directly in code:
import { Entity, PrimaryGeneratedColumn, Column } from "typeorm";
@Entity()
export class User {
@PrimaryGeneratedColumn()
id: number;
@Column()
name: string;
@Column({ unique: true })
email: string;
}
- I used repositories to perform CRUD operations:
const userRepository = dataSource.getRepository(User);
const user = new User();
user.name = "Ivan";
user.email = "ivan@example.com";
await userRepository.save(user);
-
I configured relationships between entities (OneToMany, ManyToOne, etc.) to model relationships in the database.
-
I used migrations to manage schema changes.
TypeORM is well-suited for TypeScript projects where type safety and ease of working with the database without writing a lot of SQL are important.
