Async Await problem not working in order

Question

In the following code am trying to get request() to be executed before the return

module.exports = {

func: async function (servURI, sName, APIKey) {
var res;
const options = await {
url: servURI + sName,
headers: {
"Accept-Charset": "application/x-www-form-urlencoded; charset=UTF-8",
"Token": APIKey,
"Accept-Language": "en-US,en;q=0.9,ar;q=0.8",
"User-Agent": "Bm"
}
}
async function callback0(error, response, body) {
if (!error && response.statusCode == 200) {
const info = await JSON.parse(body);
//need res to have info.id value before continue
res = info.id
console.log("cb func: "+res)
} else if (response.statusCode == 404) {
return 0;
}
}
await request(options, callback0);
console.log("sid: "+ res);
return res;
}

}

Log:

2019-05-30T13:40:49.116699+00:00 app[worker.1]: sid:undefined
2019-05-30T13:40:49.827820+00:00 app[worker.1]: cb func: YZEBzE2BWR74QdsvS8WupVdWujUI17oPYygOf4ppO-e3AN8

I'm still new to node.js, so any help would be appreciated, Thanks in advance.

Answer 1

Use ES6 syntax Promise() and .then()

Answer 2

@Gordon, that's for async/await not for promise, i still don't understand how to apply that to my code up there, its completely different code.
