I cannot export jQuery correctly; testing Node.js with mocha and chai

[EB]

I'm confused how to export jQuery correctly in order to test several functions with mocha and the assertion library chai. Hopefully this is a beginner's error...

Here is the code I am testing, with the branch `add_tests`:

https://github.com/mskilab/gGnome.js/tree/add_tests

I'm having trouble with the functions in 

https://github.com/mskilab/gGnome.js/blob/master/js/misc.js

with the tests here:

https://github.com/mskilab/gGnome.js/blob/add_tests/test/miscTest.js

So, in order to export jQuery, I include the following line: 

https://github.com/mskilab/gGnome.js/blob/add_tests/js/misc.js#L2

    const $ = require('jquery');

However, I'm still getting errors when I try to use the functions in `miscTest.js`, whereby I'm running `mocha` or `npm test`, I get a TypeError:

    TypeError: $.ajax is not a function

This is from trying to run 

    console.log(Misc.metadata);

within `misc.js`

How do I correctly export jQuery so it's recognized?

So, this is a server-side javascript environment. jQuery is more suited to a client-side environment (in a browser, not on a server). I think you're trying to use jQuery to make a request to a /metadata endpoint on a server to get some JSON. I'd suggest you use the 'request' package instead.

First, install the package:

npm install request --save

Then, you can use it in your misc.js file:

const request = require('request');

Finally, you can replace your $.ajax call with request like this:

request(Misc.server+'/metadata', function(err, response, body){
  if(err) {
    console.log(err);
    return;
  }
  console.log(body);
}

HTH,

Hi Mikkel

This is a good work around. I think you might be right---I may not have been thinking clearly about jquery. 

Thanks, Evan
