Questions about how it works or RequireJS

I'm making an application that will consume some Twitter data. I am using the library recommended by the API developers, as my application is just for consuming API I only use javascript and jQuery , then I use the TwitterJSClient library.

In this library, at the beginning of the file /TwitterJSClient/lib/Twitter.js it has the following code:

var OAuth = require('oauth').OAuth;
var qs = require('qs');

After analyzing your folder and file structure, I saw that it has some directories named oauth and qs .

When attaching this project to mine, the first one does not work because these functions do not belong to JavaScript and jQuery, ie undefined .

The little I know about RequireJS is that it loads files into another, making it possible to use them. However, even after using the RequireJS (version ~ 2.1.14) that I installed via Bower (% with%) the project does not work as it should.

The error you give is as follows:

Uncaught Error: Module name "oauth" has not been loaded yet for context: _. Use require([])
http://requirejs.org/docs/errors.html#notloaded 

I changed the project code to:

var OAuth = require(['oauth']).OAuth;
var qs = require(['qs']);

And the result changes to:

GET http://192.168.0.22:9000/oauth.js 404 (Not Found)
Uncaught Error: Script error for: oauth
http://requirejs.org/docs/errors.html#scripterror
GET http://192.168.0.22:9000/qs.js 404 (Not Found)
Uncaught Error: Script error for: qs
http://requirejs.org/docs/errors.html#scripterror 

Structure of directories and files (partial):

    images/
    scripts/
      TwitterJSClient/
        lib/
          Twitter.js

Can someone tell me a way to use TwitterJSClient in my project?
