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

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.
