Node.js ORM vs Query Builder: Which Should I Use?

What are the main differences between using an ORM and a query builder in Node.js?

ORMs (Object-Relational Mappers) allow you to interact with your database using objects, while query builders let you construct SQL queries programmatically. ORMs abstract the database interactions, making it easier to work with data as objects, whereas query builders provide more control over the SQL being executed.

Can you give me some examples of popular ORMs and query builders for Node.js?

Sure! Popular ORMs for Node.js include Sequelize and TypeORM. For query builders, you might consider Knex.js or Objection.js.

When should I choose an ORM over a query builder?

You should choose an ORM if you prefer working with objects and want to reduce boilerplate code. If you need fine-grained control over your SQL queries or are working with complex queries, a query builder might be a better choice.

Are there any performance differences between the two?

Yes, ORMs can introduce some overhead due to abstraction, which might affect performance. Query builders can be more efficient since they allow you to write optimized SQL directly.
