read files and read directory in node.js - node.js

Question

I want to know whtether the read file and read directory functions - fs.readdir(path, callback) and fs.readFile(path, options, callback) have similar functions without callback.Here, I first read all the files in given directory, and loop through all the files and upload their content to S3 bucket.
Please see the working code below.
const s3Upload = async (req, res) => {
const directoryName = "MAXIS_GAMING/Daily/"
var data = {}
let files = {}
await readFiles1(directoryName)
}
const readFiles1 = async(dirname) => {
let _files
fs.readdir(dirname, (err, files) => {
// On error, show it and return
if(err) return console.error(err);
// files is an array containing the names of all entries
// in the directory, excluding '.' (the directory itself)
// and '..' (the parent directory).
// Display directory entries
console.log(files.join(' '));
files.forEach(function(filename){
fs.readFile(dirname + filename, 'utf-8', function(err, content){
if(err) {
// onError(err);
throw err
return;
}
console.log('cont..............................',content)
console.log('filename', filename)
//await
uploadFiles(filename, content)
//onFileContent(filename, content);
})
})
})
}
const uploadFiles = async (fileName, fileContent) => {
console.log('in uploadd..........')
const GLOBAL_ACCESS_KEY_ID = 'AKIDAQWZX6B3XUBDIFHLPC5LYFTJF15XPIQ';
const GLOBAL_SECRET_ACCESS_KEY = 'Sv4Fe4h4QgErG5XoZbgeC63oczkdW3bMQfC0jvyR8bPbJ9Y97k+'
const GLOBAL_DEFAULT_REGION = 'ap-southeast-1';
const S3_IMAGE_BUCKET ='max-stg-image/stage/reports'//"max-stg-image";
const S3_IMAGE_PATH = "stage";
AWS.config.update({
accessKeyId: GLOBAL_ACCESS_KEY_ID,
secretAccessKey: GLOBAL_SECRET_ACCESS_KEY,
region: GLOBAL_DEFAULT_REGION,
});
const s3 = new AWS.S3()
const bucket = new AWS.S3()
const params = {
Bucket: S3_IMAGE_BUCKET,
Key: fileName,
Body: fileContent
};
// Uploading files to the bucket
s3.upload(params, function(err, data) {
if (err) {
throw err;
}
console.log(`File uploaded successfully. ${data.Location}`);
});
}
app.get('/home/s3Upload', s3Upload)

You can do something like this:
import { readdir } from 'fs/promises';
//or with require
const readdir = require('fs/promises').readdir;
try {
const files = await readdir(path);
for (const file of files)
console.log(file);
} catch (err) {
console.error(err);
}
