Re: IBM announces new language environment - Node.js for i

I'm a bit puzzled by your reply, Jon. Also a bit puzzled by what folks may
be expecting IBM to add to the HTTP server based on Apache. The Apache
module that Aaron referred to appeared to act as a "tunnel", accepting
connections from Web socket clients, but just forwarding them to a Web
socket server, which is evidently listening on a separate port. That seems
similar to using an Apache instance as a reverse proxy, forwarding requests
to various other Apache instances listening on various ports. So maybe the
"real" Web socket server is running under Node.js, where Apache is
forwarding conversations to it.

Regarding your comment about "full capability" concerning Node.js - can you
elaborate? I don't understand the context. Did anyone suggest that IBM's
implementation of Node.js might not be complete?

It appears to me that IBM has extended Node.js to enable connections to IBM
i objects such as programs, data queues, etc.

So we’ll just have to wait until we get a version of Apache with the
required plug-in to support web sockets I guess. Hopefully not too long a
wait - we just got the version of Apache that supports it I believe so
there’s hope. I can’t see that IBM would have bothered with Node.js if it
wasn’t going to bring the full capability.

node.js is a OO javascript environment that supports websockets that is a
bidirectional HTTP like connnection where (unlike HTTP) the socket is

held

open.

One area of application is if you need to stream real time data to

clients.

A typical application is that you stream data from a stock exchange or
in a chat application to many users.

Since it is OO javascript one node.js program can service a large number
of connections just by creating new objects for each connection in fact
very similar to AJAX in a webpage where it is possible to run several
HTTP requests at the same time.

I'm sure there are better examples than streaming video to a students
computer. :)

No nightmare. Just a different use-case. Say you're a student

attending

an

on-line course where the teacher is showing her whiteboard to class
members. She writes math equations on the white board and that the

content

is broadcast (streamed) to the browsers.
