What are the best practices for using Sequelize with async/await?

When using Sequelize with async/await, it's important to handle errors properly, use transactions when necessary, and ensure that your queries are optimized for performance.

Can you give me an example of error handling in this context?

Sure! You can use try/catch blocks to handle errors. For example:

try {
  const user = await User.findByPk(1);
} catch (error) {
  console.error('Error fetching user:', error);
}

What about using transactions?

Transactions are crucial for maintaining data integrity. You can use them like this:

const t = await sequelize.transaction();
try {
  await User.create({ name: 'John' }, { transaction: t });
  await t.commit();
} catch (error) {
  await t.rollback();
  console.error('Transaction failed:', error);
}

Any tips for optimizing queries?

Yes! Use eager loading with include to reduce the number of queries, and always select only the fields you need to minimize data transfer.
