[Javascript] Codegen client for Swagger 2.0 using API Key authentication doesn't expose a way to actually set the API Key, generated example is wrong

Description

Generated a Javascript client from this API spec:

https://api.cloudmersive.com/barcode/docs/v1/swagger

Thus creating an NPM here:

https://www.npmjs.com/package/cloudmersive-barcodeapi-client

Expected: The example code shows a way to set the Apikey

Observed: Example code does not show how to set the Apikey. Not clear how to actually set the Apikey

Swagger-codegen version

2.3.1

Swagger declaration file content or url

https://api.cloudmersive.com/barcode/docs/v1/swagger

Command line used for generation

java -jar swagger-codegen-cli.jar generate -i https://api.cloudmersive.com/barcode/docs/v1/swagger -l javascript -o .\Cloudmersive.APIClient.NodeJS\barcode --api-package cloudmersive-barcode-api-client

Steps to reproduce

Follow above steps. Note that the code example provided does NOT include a way to set the Apikey:

var Barcodeapi = require('barcodeapi');

var api = new Barcodeapi.BarcodeLookupApi()

var value = "value_example"; // {String} Barcode value

var callback = function(error, data, response) {
if (error) {
console.error(error);
} else {
console.log('API called successfully. Returned data: ' + data);
}
};
api.barcodeLookupEanLookup(value, callback);

Suggest a fix/enhancement

Show how to set the Apikey in the code example! Also, there are no docs in swagger-codegen that say how to actually do this either

Reproduce the generation with swagger-codegen-cli.jar 2.3.1, the Swagger declaration URL, and the javascript command shown in the issue. Inspect the generated BarcodeLookupApi example and compare it with the API key authentication required by the specification. Done means the example and Swagger-codegen documentation clearly show how to set the API key.
