How can I perform complex queries using Sequelize in Node.js?

You can use Sequelize's query interface to perform complex queries. For example, you can use methods like findAll, findOne, and query to build your queries.

Can you show me an example of a complex query with joins?

Sure! Here's an example: User.findAll({ include: [{ model: Post }] }); This will fetch users along with their associated posts.

What if I want to filter results based on a condition?

You can add a where clause to your query. For example: User.findAll({ where: { age: { [Op.gt]: 18 } } }); This fetches users older than 18.

How do I handle pagination in Sequelize?

You can use the limit and offset options in your query. For example: User.findAll({ limit: 10, offset: 20 }); This fetches the third page of results assuming 10 results per page.
