How to work with managed transactions in MongoDB in NestJS?

36 Views Asked by At

I'm currently working on a NestJS application with MongoDB as the database backend. I need to implement managed transactions for handling multiple database operations within a single transaction.

Can anyone provide guidance or examples on how to work with managed transactions in MongoDB within a NestJS application?

Example using Sequelize

try {

  const result = await sequelize.transaction(async (t) => {

    const user = await User.create({
      firstName: 'Abraham',
      lastName: 'Lincoln'
    }, { transaction: t });

    await user.setShooter({
      firstName: 'John',
      lastName: 'Boothe'
    }, { transaction: t });

    return user;

  });

  // If the execution reaches this line, the transaction has been committed successfully
  // `result` is whatever was returned from the transaction callback (the `user`, in this case)

} catch (error) {

  // If the execution reaches this line, an error occurred.
  // The transaction has already been rolled back automatically by Sequelize!

}
