NodeJS Async Await Insert Data to Database and Google API - node.js

Question

I'm working as API Backend with NodeJS. In case, when I insert 1 row the data will automatically updated to DB and Goolge Sheet API.
I already create the code in controller but I want to make it as Async Await, to makesure data inserted to DB first.
Here is my code:
createUser: (req, res, next) => {
bcrypt.genSalt(Number(env.SALTROUNDS_USER), (err, resultSalt) => {
bcrypt.hash(req.body.password, resultSalt, (err, hash) => {
doc.useServiceAccountAuth(creds, function(err){
// regis to db
let datauser = new modelsUsers({
email: req.body.email,
name: req.body.name,
password: hash,
phone_number: req.body.phone_number
});
//regis to GoogleSheetApi
doc.addRow(1,{
timestamps: tgl_ob,
name: req.body.name,
email: req.body.email,
phone_number: req.body.phone_number
},function(err){
if(err){
console.log(err); //errors
}
});
if(err){
console.log(err); //success
}
datauser.save((err, result) => {
if (result) res.send(result);
else res.send(err);
});
})
});
});
},

You can use util to make callbacks to promise
const GoogleSpreadsheet = require('google-spreadsheet');
const { promisify } = require('util')
const doc = new GoogleSpreadsheet(process.env.sheetid);
const creds = require('./../creds.json') // JSON file you can get from serviceaccount
createUser: (req, res, next) => {
bcrypt.genSalt(Number(env.SALTROUNDS_USER), (err, resultSalt) => {
bcrypt.hash(req.body.password, resultSalt, async (err, hash) => {
// you can also convert genSalt, salt to Promis
await promisify(doc.useServiceAccountAuth)(creds)
const info = await promisify(doc.getInfo)();
const sheets = info.worksheets;
let datauser = new modelsUsers({
email: req.body.email,
name: req.body.name,
password: hash,
phone_number: req.body.phone_number
});
const data = {
timestamps: tgl_ob,
name: req.body.name,
email: req.body.email,
phone_number: req.body.phone_number
}
// as you need to save to DB first and then add ROW to sheet
datauser.save(async (err, result) => {
if (result) {
await addRows(sheets, 1, data) // you can wrap in try catch for error handling
res.send(result);
}
else res.send(err);
});
})
});
}
function addRows(sheet, index, data) {
return new Promise((resolve, reject) => {
sheet[index].addRow(data, (err, row) => {
if (err) return reject(err)
resolve(row)
})
})
}
