Problem with: const ccxt = require('ccxt');

See original GitHub issue

OS: Windows 10
Programming Language version: Visual Studio 2017 (Universal Windows Javascript App)
CCXT version: #465
Exchange: Bitfinex
Node.js 11.9.0 installed
Method: const ccxt = require(‘ccxt’);

Hello!

I succeed to return all exchanges in chrome console with below code: console.log(ccxt.exchanges);

But I think that I don’t want to run the library in a browser. But instead in Visual Studio Debugger. Now comes the problem. When I run it in the debugger instead and NOT in a browser, I receive below commented error.

So const ccxt = require(‘ccxt’); seems to have a problem here because ‘require’ is not defined somehow. I don’t know how to implement this correctly? Please see more comments in the code snippets below. _(In the 3rd codesnippet with the ‘CORS’ error is the reason I want to Not run it in a browser but Visual Studio directly because as I understood it this can then be avoided?)

            //const Exchange = require('./js/base/Exchange')
            //Unhandled exception at line 33, column 1 in ms - appx://6b49fdc7-ae95-44f8-9223-0bfbb5025163/ccxt-master/ccxt.js
            //0x800a1391 - JavaScript runtime error: 'require' is not defined
            const ccxt = require('ccxt');

COMPLETE CODE WITH COMMENTS ABOVE EACH TO UNDERSTAND WHAT I HAVE TRIED `<body onload="myFunction();"> <script src="ccxt-master/ccxt.js"></script> <script src="js/require.js"></script> <script type="text/javascript" src="https://unpkg.com/ccxt"></script> <script type="text/javascript"> function myFunction() {

            //to fetch the resource with CORS disabled.
            let exchange = new ccxt.bitfinex();
            exchange.verbose = true;
            console.log(exchange.loadMarkets());
    }

Is this where the coding should take place when using NPM/Node.js ?

Yes, basically, you should search for “how to start programming with Node.js” tutorials. The link you posted should help. However, I’d also recommend these:
