Pulling a value from Asynchronus Function - node.js

Question

I'm working with we sockets and I have a lot of requests, so I figured it'd be best to pull the data out of the asynchronus funtion and put it in a variable outside of it. My code looks like this but I just get request [Pending]:
var variable;
var Request = require("request");
function getAsyncValue() {
return new Promise((resolve, reject) => {
Request.get(url, (error, response, body) => {
if(error) {
return reject(err);
}
var object = JSON.parse(body);
var value = object.data.available_balance;
resolve(value);
});
});
}
async function asyncWrapper() {
variable = await getAsyncValue();
return(variable);
}
printVariable = asyncWrapper();
console.log(printVariable);
Any idea on how I can achieve my goal?

Answer 1

Your asyncWrapper is a promise. You have to use await.
To use an await, you need an async function. So you can use a IIFE(Immediately Invoked Functions Expressions) async function.
async function(){
printVariable = await asyncWrapper();
console.log(printVariable);
}();

Answer 2

This was what I was looking for:
var request = require('sync-request');
var returnCode;
var getUrl = "url";
returnCode = httpGet(getUrl);
var object = JSON.parse(returnCode);
var balance = objekt.data.available_balance;
console.log(balance);
function httpGet(url){
var response = request(
'GET',
url
);
return response.body;
}

Answer 3

put your console.log inside the asyncWrapper() as following:
async function asyncWrapper() {
variable = await getAsyncValue();
console.log(printVariable);
return(variable);
}
printVariable = asyncWrapper();
the reason for doing this is because when u had console.log() after the asyncWrapper(), it will be called immediately and not in an sync manner as u would need.
or you can do the following:
Just wrap the asyncWrapper function call inside an another async method and await for the result of asynWrapper() in that. Look below:
var function1 = async function () {
printVariable = await asyncWrapper();
console.log(printVariable);
}
