Power BI Visual calling into REST APIs

[safalkishore]

I am developing a sample power bi visual after following the article - https://docs.microsoft.com/en-us/power-bi/developer/visuals/custom-visual-develop-tutorial

I am trying to use the 'request' npm package on the 'visuals.ts' on the constructor and then call into a custom API like the sample code shown below:

 request('http://www.microsoft.com', function (error, response, body) {

 console.log('error:', error); // Print the error if one occurred

 console.log('statusCode:', response && response.statusCode); // Print the response status code if a response was received

 console.log('body:', body); // Print the HTML for the Google homepage.

 });

I encounter an error on the 'pbiviz start' phase while trying the above. 

Hence trying to check if this is allowed and how I could go about looking up the build error

Also tried setting the library as shown on this page - https://github.com/microsoft/PowerBI-visuals/blob/master/Tutorial/ExternalLibraries.md#including-jav...

    },

    "externalJS": [

        "node_modules/request/request.js"

      ],

Yet the error persists
