Re: powerEXT for node.js

Hi Henrik

No they haven't abandoned anything :) One is not replacing the other. We
can use both frameworks - one for platform agnostic applications and one
for IBMi applications. The fact that the node.js platform can also run on
the IBMi is somewhat moot at the moment because IBM have not solved all
issues yet. Until very recently you could only get 1021 connections on the
IBMi but I finally got that fixed and had a PTF approved/released. There
are still some issues with orphaned processes though that they are still
working on.

Data queues - the RPG version of the Framework uses data queues, and the
node.js version uses the same topology, with redis (busmq) being used
instead of data queues.

"node.js is not a web server" - yes I knew that thanks ;)

Cheers
Kevin

Kevin,

So the programmers had to abandon whatever work they have done in RPG in
your setup? What I want to do is to be able to run node.js side by side
with ILE CGI.

Btw, node.js is not a web server but 'just' a Virtual Machine that runs
javascript on any platform. It is very similar to Java's JVM that without a
class library basically reads/writes data through StdIn and StdOut that
through the included classes can point to anything including HTTP sockets
and IFS files etc.

Neither node.js or JVM comes with a predefined structured environment like
ILE (QSYS.LIB) that has a simple structure like
/QSYS.LIB/LIBRARY/OBJECT.TYPE.

powerEXT for node is not a NPM that runs under node.js but an environment
that runs on top of node.js VM in a predefined directory structure.and then
it has a number of preinstalled node.js modules that supports web
development and SQL DB I/O on JSON resultset level thus simplifying the SQL
part that may be build by system delivered node.js modules or NPM's like
Waterline ORM.

DataQueues - what are you talking about?

I did a similar thing by rewriting the entire Renaissance Framework
server-side code in node.js. It is quite neat - each RPGLE server
program can be replaced by a node.js module that is simply "require"ed
at run-time. The developers (all RPG backgrounds) just have to write
the server programs as modules based on a boilerplate and it just
plugs right in. The client side is identical for the RPG and node

instances so nothing

to learn. It can use any database supported by the Waterline ORM and

uses

Redis for session data and to replace data queues.

Subject: [WEB400] powerEXT for node.js

Hi all,


I started testing node.js like anyone else but couldn’t figure out how
to manage a whole application, node.js seems to be very nerdy where
everybody is chasing what NPM’s to use but I found very few
descriptions on how to handle node.js in a production environment and
how to chop up code in small Apps like I know it from ILE CGI on IBM i.



So I decided to build my own ‘package’ based on the experience from
CGIDEV2 and powerEXT Core that both hide the complexity of handle HTTP
requests in and out and complex string operations.



The result can be read about here http://powerext.com/core.htm



I will make it available for download as soon I have testet the ‘package’
on IBM i and made a simple installation procedure for I - but my plan
is that it should run as a base environment on any platform that runs
node.js and it is therefore developed on a Windows PC.



Feel free to comment …
