typeorm is an Object-Relational Mapping (ORM) library for TypeScript and JavaScript applications. It provides a powerful and flexible way to interact with databases, allowing developers to work with database entities as if they were regular JavaScript objects. TypeORM supports various database systems, including MySQL, PostgreSQL, SQLite, and more, making it a versatile choice for many applications. Its features include support for migrations, relations, and eager/lazy loading, which help streamline database interactions and improve productivity.

While TypeORM is a popular choice, there are several alternatives in the Node.js ecosystem that also provide ORM capabilities. Here are a few noteworthy options:

  • bookshelf is a JavaScript ORM for Node.js that is built on top of the Knex.js SQL query builder. It provides a simple and intuitive API for interacting with relational databases while supporting features like relations, virtuals, and pagination. Bookshelf is a great option if you prefer a lightweight ORM that offers flexibility and ease of use, especially if you are already using Knex for query building.
  • knex is primarily a SQL query builder for Node.js, but it can also be used as a foundation for building your own ORM. It provides a powerful and flexible way to construct SQL queries and supports various database systems. If you need fine-grained control over your SQL queries and prefer to build your own data access layer, Knex is an excellent choice. However, it requires more manual setup compared to full-fledged ORMs like TypeORM or Bookshelf.
  • sequelize is another popular ORM for Node.js that supports various SQL dialects, including MySQL, PostgreSQL, and SQLite. It offers a rich set of features, including model validation, associations, and migrations. Sequelize is known for its extensive documentation and active community, making it a solid choice for developers looking for a comprehensive ORM solution. If you need a robust and feature-rich ORM with a focus on SQL databases, Sequelize is worth considering.

It aims to provide a more powerful and flexible alternative to Bookshelf by supporting advanced features such as eager loading, transactions, and complex queries. Objection is designed for developers who need more control over their database interactions while still benefiting from the simplicity of an ORM. If your application requires complex relationships and queries, Objection may be the right choice.

  • waterline is an ORM that is part of the Sails.js framework but can also be used independently. It provides a simple data access layer that works with various databases, including SQL and NoSQL options. Waterline abstracts the database interactions, allowing developers to work with a unified API regardless of the underlying database. If you are building an application with Sails.js or need a versatile ORM that supports multiple database types, Waterline is worth considering.

README for typeorm

TypeORM is an ORM that can run in Node.js, Browser, Cordova, Ionic, React Native, NativeScript, Expo, and Electron platforms and can be used with TypeScript and JavaScript (ES2021). Its goal is to always support the latest JavaScript features and provide additional features that help you to develop any kind of application that uses databases - from small applications with a few tables to large-scale enterprise applications with multiple databases.

TypeORM supports more databases than any other JS/TS ORM: Google Spanner, Microsoft SqlServer, MySQL/MariaDB, MongoDB, Oracle, Postgres, SAP HANA and SQLite, as well we derived databases and different drivers.

TypeORM supports both Active Record and Data Mapper patterns, unlike all other JavaScript ORMs currently in existence, which means you can write high-quality, loosely coupled, scalable, maintainable applications in the most productive way.

TypeORM is highly influenced by other ORMs, such as Hibernate, Doctrine and Entity Framework.

  • Produced code is performant, flexible, clean, and maintainable.
  • Follows all possible best practices.
  • CLI.

And more...

With TypeORM, your models look like this:

import { Entity, PrimaryGeneratedColumn, Column } from "typeorm"

@Entity()
export class User {
    @PrimaryGeneratedColumn()
    id: number

    @Column()
    firstName: string

    @Column()
    lastName: string

    @Column()
    age: number
}

And your domain logic looks like this:

const userRepository = MyDataSource.getRepository(User)

const user = new User()
user.firstName = "Timber"
user.lastName = "Saw"
user.age = 25
await userRepository.save(user)

const allUsers = await userRepository.find()
const firstUser = await userRepository.findOneBy({
    id: 1,
}) // find by id
const timber = await userRepository.findOneBy({
    firstName: "Timber",
    lastName: "Saw",
}) // find by firstName and lastName

await userRepository.remove(timber)

Alternatively, if you prefer to use the ActiveRecord implementation, you can use it as well:

import { Entity, PrimaryGeneratedColumn, Column, BaseEntity } from "typeorm"

@Entity()
export class User extends BaseEntity {
    @PrimaryGeneratedColumn()
    id: number

    @Column()
    firstName: string

    @Column()
    lastName: string

    @Column()
    age: number
}

And your domain logic will look this way:

const user = new User()
user.firstName = "Timber"
user.lastName = "Saw"
user.age = 25
await user.save()

const allUsers = await User.find()
const firstUser = await User.findOneBy({
    id: 1,
})
const timber = await User.findOneBy({
    firstName: "Timber",
    lastName: "Saw",
})

await timber.remove()
