How can I manage transactions in my backend using ORMs?

You can manage transactions in your backend using ORMs by utilizing the transaction management features they provide. Most ORMs allow you to start, commit, and rollback transactions easily.

Can you give me an example of how to implement this in a Node.js application?

Sure! In a Node.js application using Sequelize as an ORM, you can manage transactions like this:

const { Sequelize } = require('sequelize');
const sequelize = new Sequelize('database', 'username', 'password', { dialect: 'mysql' });

async function performTransaction() {
    const transaction = await sequelize.transaction();
    try {
        // Your database operations here
        await transaction.commit();
    } catch (error) {
        await transaction.rollback();
        throw error;
    }
}

What happens if a transaction fails?

If a transaction fails, you can rollback the transaction to revert any changes made during that transaction. This ensures data integrity.

Are there any best practices for transaction management?

Yes, some best practices include keeping transactions short, avoiding long-running transactions, and ensuring that all operations within a transaction are necessary.
