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.find({ name: nameA }).session(session);
  const userB = await User.find({ name: nameB }).session(session);
 
  userA.friends.push(userB._id);
