Drizzle ORM

If you know SQL, you know Drizzle ORM

Drizzle ORM is a TypeScript ORM for SQL databases designed with maximum type safety in mind. It comes with a drizzle-kit CLI companion for automatic SQL migrations generation. Drizzle ORM is meant to be a library, not a framework. It stays as an opt-in solution all the time at any levels. The ORM's main philosophy is "If you know SQL, you know Drizzle ORM". We follow the SQL-like syntax whenever possible, are strongly typed ground up, and fail at compile time, not in runtime.

Drizzle ORM is being battle-tested on production projects by multiple teams 🚀 Give it a try and let us know if you have any questions or feedback on Discord.

Features

• Full type safety
• Smart automated migrations generation
• No ORM learning curve
• SQL-like syntax for table definitions and queries
• Best in class fully typed joins
• Fully typed partial and non-partial selects of any complexity
• Auto-inferring of TS types for DB models for selections and insertions separately
• Zod schema generation
• Zero dependencies

Note: don't forget to install pg and @types/pg packages for this example to work.

import { drizzle } from 'drizzle-orm/node-postgres';
import { integer, pgTable, serial, text, timestamp, varchar } from 'drizzle-orm/pg-core';
import { InferModel, eq, sql } from 'drizzle-orm';
import { Pool } from 'pg';

export const users = pgTable('users', {
  id: serial('id').primaryKey(),
  fullName: text('full_name').notNull(),
  phone: varchar('phone', { length: 20 }).notNull(),
  role: text('role', { enum: ['user', 'admin'] }).default('user').notNull(),
  cityId: integer('city_id').references(() => cities.id),
  createdAt: timestamp('created_at').defaultNow().notNull(),
  updatedAt: timestamp('updated_at').defaultNow().notNull(),
});

export type User = InferModel<typeof users>;
export type NewUser = InferModel<typeof users, 'insert'>;

export const cities = pgTable('cities', {
  id: serial('id').primaryKey(),
  name: text('name').notNull(),
});

export type City = InferModel<typeof cities>;
export type NewCity = InferModel<typeof cities, 'insert'>;

const pool = new Pool({
  connectionString: 'postgres://user:password@host:port/db',
});

const db = drizzle(pool);

// Insert
const newUser: NewUser = {
  fullName: 'John Doe',
  phone: '[phone]',
};
const insertedUsers /* : User[] */ = await db.insert(users).values(newUser).returning();
const insertedUser = insertedUsers[0]!;

const newCity: NewCity = {
  name: 'New York',
};
const insertedCities /* : City[] */ = await db.insert(cities).values(newCity).returning();
const insertedCity = insertedCities[0]!;

// Update
const updateResult /* : { updated: Date }[] */ = await db.update(users)
  .set({ cityId: insertedCity.id, updatedAt: new Date() })
  .where(eq(users.id, insertedUser.id))
  .returning({ updated: users.updatedAt });

// Select
const allUsers /* : User[] */ = await db.select().from(users);

// Select custom fields
const upperCaseNames /* : { id: number; name: string }[] */ = await db
  .select({
    id: users.id,
    name: sql<string>`upper(${users.fullName})`,
  })
  .from(users);

// Joins
// You wouldn't BELIEVE how SMART the result type is! 😱
const allUsersWithCities = await db
  .select({
    id: users.id,
    name: users.fullName,
    city: {
      id: cities.id,
      name: cities.name,
    },
  })
  .from(users)
  .leftJoin(cities, eq(users.cityId, cities.id));

// Delete
const deletedNames /* : { name: string }[] */ = await db.delete(users)
  .where(eq(users.id, insertedUser.id))
  .returning({ name: users.fullName });

sequelize

Sequelize is a promise-based Node.js ORM for Postgres, MySQL, MariaDB, SQLite, and Microsoft SQL Server. It features solid transaction support, relations, eager and lazy loading, read replication, and more. Compared to Drizzle ORM, Sequelize has a larger community and more extensive documentation but may lack some of the type safety features that Drizzle ORM offers.

typeorm

TypeORM is an ORM for TypeScript and JavaScript (ES7, ES6, ES5). It supports many database systems including MySQL, MariaDB, PostgreSQL, SQLite, and more. TypeORM is known for its extensive feature set and active community. It provides decorators for defining entities and supports advanced features like migrations, caching, and more. Compared to Drizzle ORM, TypeORM offers more features but may be more complex to set up and use.

knex

Knex.js is a SQL query builder for PostgreSQL, MySQL, MariaDB, SQLite3, and Oracle. It features a flexible and powerful API for building SQL queries and managing database schema. While Knex.js is not a full-fledged ORM, it can be used in conjunction with other libraries to provide ORM-like functionality. Compared to Drizzle ORM, Knex.js offers more control over raw SQL queries but lacks the built-in type safety and higher-level abstractions.
