[nodejs] require remote modules

[Joson Mandaro]

Hi,

I have some modules on the other pc (url = "http://192.168.1.11:8080/a.js"). How to load this file remotely?

There is a function "loadModule" in node.js.  when I call it loadModule(url, self, callback), it threw out an error: loadModule is undefined.

And I found require() function can't get the remote file.

Best regards,

Joson

Short answer: you dont require a module over networks without work

Long answer:
spawn up an http.createClient, requests the script, buffer the data
from the response, fire off this: "var module = new Module(url);
module._compile(contents,filename);module.loaded = true"
the arguments to Module will be the key the module is cached on so be
wary. The "request" module for node on github makes this fairly easy.

A big reason this isnt supported is the blocking nature of require and
the non-blocking nature of all network io in node. (dont want to wait
10^6~ as long for a net file that blocks compared to a fs one)

require.async( "http://192.168.1.11:8080/a.js", function (er, a) {
if (er) return console.error("Failed loading a.js")
doSomething(a)
})

Doing require("http://192.168.1.11:8080/a.js") is supported with
nodules [1]. Static analysis is used to fetch the module
asynchronously, so the require can return synchronously.

thank all of you. I've read the nodules. It's a very useful tool, thanks.
