node.js swagger x-ms-dynamic-value - node.js

Question

I'm using swagger with node.js. I want to use x-ms-dynamic-values to return values to my parameter dynamically.
Basically the first parameter will have a URL then the node.js endpoint will make a get request to that URL and pull back lets say questions, Each URL can have a different amount of questions and the questions can also vary. The get request can get a json response with amount of questions on the page. In my next parameter I want to be able to select a question based on that response.
This is where the x-ms-dynamic-values will come in to play, But I'm nearly 100% sure there are no examples of this being used with node.js only thing I could find was c# example which i will link under this.
So basically my questions is, can anyone provide my with a little example of the node.js I may be able to work from ?
example of the swagger code :
"paths":{
"/api/contacts/{name}":{
"get":{
"tags":[
"DynamicSchemas"
],
"summary":"Get Contact Info",
"description":"Gets contact info of the specified type",
"operationId":"GetContactInfo",
"consumes":[
],
"produces":[
"application/json",
"text/json",
"application/xml",
"text/xml"
],
"parameters":[
{
"name":"name",
"in":"path",
"required":true,
"type":"string",
"x-ms-summary":"Contact Name"
},
{
"name":"contactType",
"in":"query",
"description":"Try either \"Phone\" or \"Email\"",
"required":true,
"type":"string",
"x-ms-summary":"Contact Type"
}
],
"responses":{
"200":{
"description":"OK",
"schema":{
"$ref":"#/definitions/ContactInfo"
}
},
"400":{
"description":"Invalid type specified"
},
"default":{
"description":"OK",
"schema":{
"$ref":"#/definitions/ContactInfo"
}
}
}
