Comparison of Prisma ORM and TypeORM

Prisma ORM and TypeORM, ORM (Object Relational Mapping) tools used to facilitate database operations in Node.js projects, are among the most preferred solutions in modern web development. In this article, we will technically examine the differences between Prisma ORM and TypeORM, their advantages, and which might be more suitable in different scenarios.

What are Prisma ORM and TypeORM?

Prisma ORM is a next-generation, schema-based ORM that provides fast and secure database access. It stands out with type safety and strong automation features. TypeORM, on the other hand, is a powerful open-source ORM popular for its TypeScript support, works with the classic entity model and offers flexible configuration. Both solutions can be integrated with many popular databases like PostgreSQL, MySQL, MariaDB.

Installation and Ease of Use

The installation of Prisma ORM is as follows:

npm install prisma --save-dev
npx prisma init

TypeORM installation is as follows:

npm install typeorm reflect-metadata

In terms of ease of use, Prisma ORM stands out with its CLI tool and automatic code generation, while TypeORM is more suitable for its classic OOP structure.

Basic Code Comparison

Adding a User with Prisma ORM

// create user with prisma
default async function createUser(prisma, data) {
  return await prisma.user.create({ data });
}

Adding a User with TypeORM

// create user with typeorm
import { getRepository } from "typeorm";
import { User } from "./entity/User";

default async function createUser(data) {
  const userRepository = getRepository(User);
  const user = userRepository.create(data);
  return await userRepository.save(user);
}

As seen, with Prisma ORM the process is shorter and has higher type safety; while in TypeORM a more classic entity-repository approach is preferred.

Advantages and Disadvantages

Feature	Prisma ORM	TypeORM
Type Safety	Yes	Partly
Supported Database	Wide	Very Wide
Migration Management	Modern and Automatic	Classic, Manually Controllable
Documentation	Very Good	Medium
Flexibility	Schema-Based	More Flexible

While Prisma ORM stands out in terms of performance and developer experience, TypeORM may be preferred for advanced customization and its closeness to the classic OOP model.

Conclusion: Which Should You Choose?

As we have examined under the title "Comparison of Prisma ORM and TypeORM", both solutions offer different advantages. If your priority is type safety, rapid development, and a modern API, Prisma ORM stands out. TypeORM may be more suitable for large OOP-based projects and those seeking more flexibility. Making your choice according to the needs of your project will be the best solution.
