Commit/rollback A Knex Transaction Using Async/await

I'm test driving the ES7 async/await proposal using this module to emulate it. I'm trying to make knex.js transactions play well with them, as a starting point. Example code: async

Solution 1:

You might be able to achieve this with something similar to this

function createTransaction() {
  return new Promise((resolve) => {
    return knex.transaction(resolve);
  });
}

async function() {
  const trx = await createTransaction();
  ...
  trx.commit();
}

Solution 2:

Building off of this Knex Transaction with Promises, it looks like it should be along these lines:

// assume `db` is a knex instance

insert: async (function(db, data) {
  const trx = db.transaction();
  try {
    const idUser = await(user.insertData(trx, data));
    trx.commit();
  } catch (error) {
    trx.rollback();
    throw error;
  }

  return {
    idUser: idUser
  }
})

Solution 3:

You can try this:

async function() {
  await knex.transaction( async (trx) => {
     ...
     trx.commit();
  }
}
