Javascript require function giving ReferenceError require is not defined

Question

Basically, I am using javascript to scrape data from Google Play store using:

1-Request

2-Cheerios

3-QueryString

I used Google Market API from Github which uses require as following:

var request = require('request'); 
var cheerio = require('cheerio'); 
var qs = require('querystring');

But I am getting the following

ReferenceError: require is not defined ...

So, I don't have a requirement in javascript which is either new for me or this is something out of the ordinary.

Answer 1

RequireJS is a JavaScript file and module loader which is optimized for in-browser use, but it can be used in other JavaScript environments, like Rhino and Node. Using a modular script loader like RequireJS will improve the speed and quality of your code. Use the follows mentioned below:-

IE 6+ .......... compatible ✔ 
Firefox 2+ ..... compatible ✔ 
Safari 3.2+ .... compatible ✔ 
Chrome 3+ ...... compatible ✔ 
Opera 10+ ...... compatible ✔
