Re: Rise of Node -- WEB400

Ah.. I must have missed another discussions somewhere.

Actually, I get a lot of custom work, as does Aaron. Aaron is very fluent
in the new technologies and excited about them! So we may each see
different the best way to solve an issue.

But recently I was "forced" to write a solution for a customer using
NodeJS. And I am liking it. :) The customer would have preferred and RPG
solution because they realize their programmer could take what I did with
RPG and learn that... smaller learning curve once it's running.

But now because it's node, well... that either means many hours and dollars
of learning for their sole programmer, or keeping me on as a consultant
indefinitely. While most consultants like the former (and count on it for
income), I don't... I have enough to keep me busy.

But, I love using the new stuff.. so I will pick and choose the projects
and pass others on to Aaron, et all. :)

I think that's kind of the work Aaron does, so he probably sees a
disproportionate number of those.

I think "lots of shops" is also an exaggeration. But also subjective.

I've always liked JS and for me, if I can't use RPG, I'll use Node for
sure. But, with how quickly it's updated, and how the updates seem to
break things, it's a learning curve. In the RPG world we're used to even
our RPGII programs still working with an OS upgrade, or PTF, etc, with
maybe a recompile at the most is needed. Most times not even that. Not
with node.

The biggest example is from Node4 to Node6 and the complete change of how
the db2 functions work. Something that is integral to a Node application
on the IBMi. Why? IBMi deals with data! Not just web pages and
storefronts.

The biggest change was moving db functions to asynchronous in nature.
That's going to trip up anyone that isn't very familiar with async
calls,or just thinks they can just change the require for db2(a) in their
source.

I had put together an encapsulated set of Node functions to do DB stuff
(return result sets, insert, update, etc). It took me a few hours to
update it so it would work as it did before with node6 (I chose not to use
the available but no longer update synchronous versions) which of course
also meant updating anything and everything that called those functions as
well.

And of course, the examples are terrible. Most, that aren't IBM, are just
copied from IBM with little or no change.

I have more thoughts on that which I will save for a later date.. .;)
While this type of thing is frustrating, I also find it invigorating.
