Running console commands through node inspector?

Question

Running console commands through node inspector?

I have connected node inspector to my running node.js program. But I'd like to issue commands through the console - not necessarily on a breakpoint. For example, I have global variables and functions in my server.js program. For example:

var express = require('express');
var app = express();

function test() {
    console.log('yo');
}

app.listen(3000);

Now in node-inspector I go into the console and I type 'test()' and it returns "ReferenceError: test is not defined", same things with global variables I type 'app' and it tells me it's not defined. Any idea how to make this thing work? I just want to run my node program and then issue commands to it via a command line interface.

@foreyez,

Your question inspired me to make an npm module that lets you debug (via command line) a running node.js application without setting breakpoints or needing to make variables global:

Hope that helps!

The reason why it doesn't work as you expected is that all your variables and functions are local to your module (application) and you can't access them from a global context.

You can save them in the global scope if you want to access them from anywhere (including from the console when not stopped on a breakpoint):

var express = require('express');
var app = express();

function test() {
    console.log('yo');
}

app.listen(3000);

global.test = test;
