Compare Drizzle ORM and TypeORM in terms of architecture and performance in Node.js.

Short answer

Drizzle is a lightweight, zero-overhead SQL-like query builder without binary engines, while TypeORM is a traditional ORM using the Data Mapper/Active Record patterns and relying on reflection and decorators.

Explanation

Drizzle is simple and closely resembles standard SQL (If you know SQL, you know Drizzle), needs no separate Query Engine, and supports Edge and Serverless environments with fast startup and full type safety. TypeORM, by contrast, offers familiar features for Java/C# developers, such as lazy loading and automatic complex relations, but has more setup complexity and slower performance.

Code example

// Drizzle ORM
const result = await db.select().from(users).where(eq(users.id, 1));

Common mistakes

• Overusing TypeORM's automatic Eager Loading, which generates large, inefficient SQL queries.

Follow-up questions
