CODE EXAMPLE FOR JAVASCRIPT

perform database transaction with 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!

}
