如何验证Sequelize事务并使其看起来更好

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

const User = sequelize.define('User', {
  // 定义模型的属性
  name: Sequelize.STRING,
  age: Sequelize.INTEGER,
});

User.createWithTransaction = async function (name, age) {
  const transaction = await sequelize.transaction();
  try {
    const user = await User.create({ name, age }, { transaction });
    // 其他数据库操作...
    await transaction.commit();
    return user;
  } catch (error) {
    await transaction.rollback();
    throw error;
  }
};

try {
  const user = await User.createWithTransaction('John Doe', 25);
  console.log('User created:', user);
} catch (error) {
  console.error('Error creating user:', error);
}
