Not Needed
The provided withTransaction and withSession helpers make running transactions very simple, but it's difficult to get the results of the operation back.
Both functions take a lambda as an argument that must return a Promise, but the functions don't pass through the value that the promise resolves to. This means that I need to create a wrapper function like this in order to get the return value:
runTransaction(writeFunc) { let writeResults = null; const txnFunc = session => ( writeFunc(session) .then((results) => { writeResults = results; }) ); return this.client.withSession(session => session.withTransaction(txnFunc))) .then(() => { return writeResults; }); }
It's not the end of the world, but it would be nice if these functions could just pass through the results.
