Retrieve the attributes from a file using nodejs? - node.js

Question

Hi I'm looking for an nodejs code which would probably return the attributes of each file in a folder. I developed the code to retrieve all the file name in a folder and another code to list data's of filename provide by us. But actually I need to return all the files names in a folder with its column name. I'm new to nodejs so someone help me please.
LISTING DATA CODE:
const AWS = require('aws-sdk');
const neatCsv = require('neat-csv');
var s3 = new AWS.S3({});
exports.handler = (event,context,callback)=>{
const params = {
Bucket:'ml-framework-api',
Key: wavicle.csv
};
s3.getObject(params,async(err, result) => {
if (err){
return console.error(err);
}
neatCsv(result.Body).then((parsedData) => {
callback(null,parsedData);
})
})
}
LISTING FILE IN S3:
const AWS = require('aws-sdk')
const s3 = new AWS.S3({
accessKeyId:'-------------',
secretAccessKey:'-------------------',
region:'ap-south-1'
})
const params = {
Bucket:'wavicle'
}
s3.listObjects(params,(err,data)=>{
if(err){
return console.log(err)
}
console.log(data)
})

It's best to start with node's file system api documentation.
Here is a simple example of how to get information about files of a folder (there are many ways, this is quickly from the example in the documentation above):
const fsp = require("fs/promises");
async function dirFilesInfo(path) {
const dir = await fsp.opendir(path);
for await (const dirEntry of dir) {
const fileInfo = await fsp.stat("./" + dirEntry.name);
console.log(dirEntry.name, fileInfo);
}
}
dirFilesInfo("./").catch(console.error);
