Node.js 7 how to use sequelize transaction with async / await?

Question

Node.js 7 and up already support async/await syntax. How should I use async/await with sequelize transactions?

Answer 1

async () => {
  let t;

  try {
    t = await sequelize.transaction({ autocommit: true});

    let _user = await User.create({}, {t});

    let _userInfo = await UserInfo.create({}, {t});

    t.afterCommit((t) => {
      _user.setUserInfo(_userInfo);
      // other logic
    });
  } catch (err) {
    throw err;
  }
}
