A simple use case for transaction

const { runInTransaction } = require('mongoose-transact-utils');

const { User } = require('./models');

// any queries or write you want to do using transaction
(async () => {
  // runInTransction catches any error in the callback to abort the transaction session
  // and then rethrows the error for you to handle the reporting
  await runInTransaction(async session => {
    // run any queries here
    await addFriend('John', 'Jane', session);
  });

  console.log('John and Jane are friend now!');
})();

async function addFriend(nameA, nameB, session) {
  const userA = await User.findOne({ name: nameA }).session(session);
  const userB = await User.findOne({ name: nameB }).session(session);

  userA.friends.push(userB._id);
  userB.friends.push(userA._id);

  await userA.save();
  await userB.save();
}
