Transaction support in nodejs

Is there any transaction support in nodejs similar to EJB for java. I don't seem to find any. Most of the posts suggest using EJB's in addition to nodejs.

Would vert.x be better in such a situation. I need to set up a payment gateway on an asynchronous model. Wondering whether to go for vert.x or nodejs.

As @Wangot pointed out, there are transactions in various Node.js packages, and sequelize is a great package because it can connect to various SQL-based databases.

If you use sequelize, and if you come from a java background, then also take a look at the zb-sequelize npm package. It simplifies transaction management extremely by adding 2 decorators: @Transactional and @Tx

import { Transactional, Tx } from 'zb-sequelize';

@Transactional
function fooBar(@Tx transaction) {
  foo(transaction);
  bar(transaction);
}

@Transactional
function foo(@Tx transaction) {
}

@Transactional
function bar(@Tx transaction) {
}

If you've worked with Spring before, then this will probably look familiar.

You can use an ORM for Node.js that has support for transaction like Sequelize.js. Although there are some limitation but can support a simple implementation.

Here is a sample code from sequelize

 return sequelize.transaction().then(function (t) {
  return User.create({
    firstName: 'Homer',
    lastName: 'Simpson'
  }, {transaction: t}).then(function (user) {
    return user.addSibling({
      firstName: 'Lisa',
      lastName: 'Simpson'
    }, {transaction: t});
  }).then(function () {
    t.commit();
  }).catch(function (err) {
    t.rollback();
  });
});
