How can I improve the performance of Sequelize in my Node.js application?

To improve Sequelize performance, consider using raw queries for complex operations, optimizing your database indexes, and using pagination for large datasets.

What are some common pitfalls to avoid when using Sequelize?

Common pitfalls include not using transactions for bulk operations, failing to properly manage connections, and not leveraging eager loading for related data.

Can you explain how to use transactions in Sequelize?

Sure! You can use transactions in Sequelize by wrapping your operations in a transaction object. Here's a basic example:

const t = await sequelize.transaction();
try {
  await User.create({ name: 'John' }, { transaction: t });
  await Profile.create({ userId: user.id }, { transaction: t });
  await t.commit();
} catch (error) {
  await t.rollback();
}
