In the case of reading files from the local file system, Node.js
async-await adds 10-25 times to complete the read cycle in comparison to
synchronous processes written in Python. Imagine how much longer that would
take if a batch process were working against a remote database which
entails not only reading from a file system, but add to that the
requirements of inter-system communications.

To me, that would be a strong case for using RPG to implement batch
processes against IBM i databases as opposed to force-fitting that into a
Node.js service.

I agree, and in my case I normally would use RPG if it's an option. But,
sometimes it's not.

Example, as Aaron knows I am working on a project for a customer that uses
Braintree (which I will hold my tongue about their sandbox.. contact me
offline for a good laugh). He is too! A different customer though.

Anyhow, Braintree doesn't allow traditionally HTTP requests. They only
allow use of their SDKs, which are available in a host of languages, node
being one of them, and the one I chose to use (I love JS...)

Sure, I may be able to spend days parsing their requests, finding the
endpoints used in the SDKs, etc, and use RPG, but I decided to use this as
a real POC project for node. All my others weren't real production, just
samples. http://nodejs.bvstools.com:5250/

My customer really wanted me to use RPG (GETURI, YAJL, etc). Well, I
couldn't in this case.

So while there are instances where I wish things were sync, yes, I had to
"force" them. I was planning on putting node 8 on for the new promise
features but decided for now, I'll leave it as is.

I got the project done (still in testing) and learned a lot in the process,
some good, some bad, about the evolution of node and how we can use it on
the IBM i in real world cases.

One day when I can collect my thoughts and see how the process actually
performs ITRW I shall pen an article about my journey at fieldexit.com.
