Azure Functions [JavaScript / Node.js] - HTTP call, best practice

Question

From my Azure function (which works in Node.js, called by the EventHub message), I would like to make a request to send to an external page. Sort of:

module.exports = function (context, eventHubMessages) {

var http = require("http");

context.log('JavaScript Function triggered by eventHub messages ');

http.request(post_options, function(res){
    ...
})

context.done();

The code above will probably work, but I doubt it is not antipattern.

Imagine a situation when thousands of functions are launched in a short time - for each execution we need to create an HTTP client and create a connection ...

From short research, I found some solution for C # Azure functions: https://docs.microsoft.com/en-us/azure/architecture/antipatterns/improper-instantiation/ which uses the static HttpClient class.
