I'm new to Javascript. I'm trying to load the following script using Node.js (ver. 0.8.8, it has to be done in this specific version), OS - Windows 10:
//require('look').start();
var main = require('skilap-core');
if (process.argv[2]=="automated") {
process.on("message",function (msg) {
if (msg.c == "startapp") {
var app = main.createApp(msg.data);
app.startApp(__dirname+"/data",function (err) {
process.send({c:"startapp_repl",data:err})
});
}
})
} else {
var app = main.createApp();
app.startApp(__dirname+"/data",function (err) {
if (err) console.log(err);
});
module.exports = app;
}
But I get the following error:
> TypeError: Object #<Object> has no method 'createApp'
at Object.<anonymous> D:\Downloads\skilap\skilap\app.js:13:17)
at Module._compile (module.js:449:26)

at Module.runMain (module.js:492:10)
at process.startup.processNextTick.process._tickCallback(node.js:244:9)
As I understand, the module loads correctly, but doesn't compile. I've done research in the web and also saw other related questions on this site, but I cannot see what the problem actually is. What does the error mean and what needs to be changed to launch the app? Any help would be appreciated.
You require a module I've never heard of:
var main = require('skilap-core');
This is a javascript object. In your code you are trying to call a createApp() method on that object:
var app = main.createApp();
The main object does not have the createApp() function.
I would use a debugger or insert a console.log(main) after the require to see what the object actually looks like.
I used npm pack skilap-core to download it as a tgz file and examine it. There doesn't appear to be a createApp() function at all. It appears to want to take some kind of custome webapp as a parameter:
module.exports = function (webapp) {
var app = webapp.web;
var ctx = webapp._ctx;
var prefix = webapp.prefix;
var api = webapp;
app.get(prefix, function (req, res, next) {
res.redirect(prefix+"/user");
})
app.get("/", webapp.layout(), function(req, res, next) {
...
I changed the line var main = require('skilap-core') to var main = require('./modules/core/lib/core.js') (the path to the module file) and the module started working.
