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!
}
