Introduction
Object-Relational Mapping (ORM) libraries have become essential tools in modern TypeScript development, bridging the gap between application code and database systems. A good ORM not only simplifies database interactions but also enhances type safety, improves developer productivity, and helps maintain clean, maintainable code.
In 2025, TypeScript developers have several mature ORM options to choose from, this article provides a comprehensive comparison of five leading TypeScript ORMs: Drizzle ORM, Prisma ORM, TypeORM, Sequelize, and MikroORM.
Drizzle ORM
Drizzle is a lightweight, TypeScript-first ORM with a SQL-centric approach and zero dependencies — ideal for serverless environments. Described as "a headless TypeScript ORM with a head," it emphasizes familiarity: "If you know SQL, you know Drizzle."
Highlights:
- Dual query APIs (SQL-like and relational)
- Zero dependencies (~7.4kb min+gzip)
- Fully built in TypeScript
- Schema defined in TypeScript, closely mirroring SQL
- Dialect-optimized and supports automatic migrations via Drizzle Kit
Code Example:
import { pgTable, serial, varchar } from 'drizzle-orm/pg-core';
export const users = pgTable('users', {
id: serial('id').primaryKey(),
name: varchar('name', { length: 50 }),
email: varchar('email', { length: 100 }),
});
Prisma ORM
Prisma is a modern ORM for Node.js and TypeScript that prioritizes developer experience and type safety through a declarative, schema-first approach and powerful tooling.
Highlights:
- Define models in Prisma Schema Language (PSL)
- Auto-generated, type-safe client with strong IDE support
- Declarative migrations via Prisma Migrate
- Visual database management with Prisma Studio
- Introspect existing databases into schema
- Raw SQL support when needed
- Scaling tools like Prisma Accelerate and Pulse
Code Example:
// schema.prisma
model User {
id Int @id @default(autoincrement())
name String
email String @unique
}
// Usage
const user = await prisma.user.create({
data: { name: 'Alice', email: 'alice@example.com' },
});
TypeORM
TypeORM is a flexible and mature ORM for TypeScript and JavaScript that supports both Active Record and Data Mapper patterns, making it adaptable to different project architectures.
Highlights:
- Define entities using TypeScript classes and decorators
- Supports complex relationships and lazy/eager loading
- Powerful SQL-like query builder
- Migration tools for schema evolution
- Works with multiple databases and across platforms
- Dual architectural pattern support (Active Record & Data Mapper)
- Repository abstraction for structured data access
Code Example:
import { Entity, PrimaryGeneratedColumn, Column } from 'typeorm';
@Entity()
export class User {
@PrimaryGeneratedColumn()
id: number;
@Column()
name: string;
@Column({ unique: true })
email: string;
}
Sequelize ORM
Sequelize is a mature, feature-rich ORM for Node.js with solid support for TypeScript. It balances abstraction and control with a comprehensive, Promise-based API.
Highlights:
- Async/await-friendly with Promise-based API
- Define models with validations, associations, and data types
- Supports PostgreSQL, MySQL, MariaDB, SQLite, and SQL Server
- Robust transaction and connection pooling support
- Comprehensive relationship handling (1:1, 1:N, N:M)
- Lifecycle hooks and raw SQL support
Code Example:
import { Sequelize, DataTypes } from 'sequelize';
const sequelize = new Sequelize('sqlite::memory:');
const User = sequelize.define('User', {
id: { type: DataTypes.INTEGER, autoIncrement: true, primaryKey: true },
name: DataTypes.STRING,
email: { type: DataTypes.STRING, unique: true },
});
MikroORM
MikroORM is a TypeScript-first ORM for Node.js, built on the Data Mapper, Unit of Work, and Identity Map patterns. It emphasizes type safety, clean architecture, and domain-driven design.
Highlights:
- Type-safe, decorator-based entity definitions
- Data Mapper for clean domain/data separation
- Unit of Work for change tracking and batching
- Identity Map to avoid duplicate instances
- Powerful query builder and migration system
- Supports PostgreSQL, MySQL, MariaDB, SQLite, MongoDB
Code Example:
import { Entity, PrimaryKey, Property } from '@mikro-orm/core';
@Entity()
export class User {
@PrimaryKey()
id!: number;
@Property()
name!: string;
@Property({ unique: true })
email!: string;
}
Comprehensive Comparison
Feature | Drizzle | Prisma | TypeORM | Sequelize | MikroORM |
---|---|---|---|---|---|
Philosophy | SQL-first, lightweight | Schema-first, declarative | Flexible, SQL-friendly | Traditional ORM | Data Mapper, Unit of Work |
