In Node.js, how do I “include” functions from my other files?

Question

Let\'s say I have a file called app.js. Pretty simple:

var express = require(\'express\');
var app = express.createServer();
app.set(\'views\', __dirname + \

Include file and run it in given (non-global) context

fileToInclude.js

define({
    "data": "XYZ"
});

main.js

var fs = require("fs");
var vm = require("vm");

function include(path, context) {
    var code = fs.readFileSync(path, 'utf-8');
    vm.runInContext(code, vm.createContext(context));
}


// Include file

var customContext = {
    "define": function (data) {
        console.log(data);
    }
};
include('./fileToInclude.js', customContext);
