Hi Kevin,
Starting sometime next year, we will be developing browser interfaces
to our IBM i. We will be using Microsoft ASP.NET running on IIS web
servers on windows. We will connect the browser pages to the IBM i
using web services (built with a .NET Data Provider that can access
IBM i DB2 files and COBOL and CL programs via stored procedures). Our
ecommerce team already does this--which is why we are starting down the same road.
Once we get our COBOL developers up and running with ASP.NET and web
services, I would like to expand our capabilities with Node.JS on the
IBM i . JavaScript will be one of the languages our COBOL developers
will have learned as part of .NET web development. So we should be
able to use Node.JS to create web services that can access a wider
variety of IBM i resources than a .NET Data Provider--plus be using
one language
(JavaScript) in the browser and in the web services.
I agree performance may be an issue with the XML extensions. I'm wait
and see about that. However, our browser interfaces would probably be
used by no more than several hundred to a few thousand concurrent
users. I don't think we will be taxing the scalability of any of the tools mentioned.
I want to learn about reverse proxies is because it might be possible
to run IIS on a windows machine that proxies a Node.JS web server on
the IBM i. This would allow us to access our .NET Data Provider web
services and our Node.JS web services on the same IIS server. If we
don't have a need for any .NET code in a particular app, we could
bypass the IIS server altogether and instead use the IBM i HTTP server as a reverse proxy.
We are a COBOL shop and will continue to use COBOL for business logic
(when needed) on the back end.
Thanks,
Kelly

It's a topology that should work - but it remains to be seen what sort
of overhead the XML-based extensions add to the equation. JavaScript
is my favourite language but I wouldn't want to use it server side
just for the sake of it. I would be interested to see what your use
cases are that warrant the use of JavaScript over normal compiled RPG (or COBOL).

However, the apps I make will be targeted at employees in our company,

in Node.JS. It's the server-side access to IBM i resources using JavaScript.

Hi Kelly,
Apache on IBM i still doesn't support Web Sockets and that is a
mainstay
Sockets but it isn't included in the IBM i version yet (to my knowledge).
support Web Sockets.
I have nginx running on IBM i based on the perzl.org AIX port (
http://www.perzl.org/aix/index.php?n=Main.Nginx) and nginx *does*
nginx setup on IBM i***).
Here are some stats on webserver popularity:

Btw, I've setup a site on bitbucket.org where Node.js collaboration
can happen more easily: https://bitbucket.org/litmis/nodejs
Why did I set it up?
- We need a place to easily post/refine code examples**.
- We need a place to log tasks needing to take place (i.e. document
- We need to start conditioning the IBM i community on how to useprofile.
modern tooling for "social coding" (i.e. Git + fork/pull)****

What are people's thoughts about running web servers as reverse
proxies for Node.JS servers on the IBM i?
I assume one could set up an IBM HTTP server as a reverse proxy for
a Node.JS server. The IBM HTTP server could handle static content;
the Node.JS server could deliver web services for dynamic content.
I also assume WebSphere web server could also be set up as a
reverse proxy for Node.JS. Would there be any benefits to using
WebSphere instead of the IBM HTTP server as a reverse proxy on the IBM i?
I currently have NGINX set up as a reverse proxy for a Node.JS
server on a windows machine (a learning environment). I like the
fact that NGINX and Node.JS are both event driven, making them fast
and scalable. I'm not sure I will ever really need the scalability
NGINX offers. IBM HTTP server will very likely meet all of my
needs. Yet, out of curiosity, does anyone know if there are plans
to port NGINX (or some other event driven web server) to the IBM i?
Thanks,
Kelly Cookson
