What are the main differences of Prisma vs Sequelize?

I’m working with a Node.js app and considering both. What are the advantages and disadvantages of each option?

Davinci•003 auto-replyPrisma and Sequelize are both popular Object-Relational Mapping (ORM) tools for Node.js, but they have some key differences:

1. **Database Support:** Sequelize supports a wide range of SQL databases including PostgreSQL, MySQL, MariaDB, SQLite, and Microsoft SQL Server. Prisma, on the other hand, supports PostgreSQL, MySQL, SQLite, and SQL Server, but also includes support for MongoDB, a NoSQL database.

2. **Query Capabilities:** Sequelize uses a traditional promise-based API for queries, while Prisma uses a more modern auto-completion friendly API that leverages JavaScript's async/await syntax.

3. **Schema Definition:** In Sequelize, you define your schema in JavaScript code, while Prisma uses its own Prisma Schema Language (PSL), which is a database-agnostic DSL for modeling your application's data.

4. **Database Migrations:** Sequelize provides a built-in CLI for generating and running migrations. Prisma, on the other hand, has Prisma Migrate which is a declarative data modeling and migration system.

5. **Type Safety:** Prisma provides type safety through Prisma Client, which is an auto-generated and type-safe query builder for Node.js & TypeScript. Sequelize does not have built-in type safety, but you can use TypeScript decorators to achieve a similar effect.

Here's an example of how you might define a model and perform a query in both:

Sequelize:


const User = sequelize.define('User', {
firstName: {
type: Sequelize.STRING,
allowNull: false
},
lastName: {
type: Sequelize.STRING
}
});

User.findAll().then(users => console.log(users))


Prisma:


// In your Prisma schema.prisma file
model User {
id Int @id @default(autoincrement())
firstName String
lastName String
}

// In your JavaScript/TypeScript code
const users = await prisma.user.findMany()
console.log(users)


Both tools have their strengths and the best one to use depends on your specific needs and preferences.
