Node.js ORM: TypeORM vs Sequelize

What are the main differences between TypeORM and Sequelize?

TypeORM is a TypeScript-based ORM that supports Active Record and Data Mapper patterns, while Sequelize is a promise-based ORM for Node.js that primarily uses the Active Record pattern.

Which one is better for a TypeScript project?

TypeORM is generally preferred for TypeScript projects due to its native TypeScript support, making it easier to work with types.

Can you give me examples of when to use each?

Use TypeORM when you need advanced TypeScript features and complex relationships. Use Sequelize for simpler projects or when you need a more established community.

What are the performance differences between them?

Performance can vary based on use case, but TypeORM may have a slight overhead due to its TypeScript features, while Sequelize is often faster for simpler queries.
