JavaScript Retrieve multiple properties from multiple files simultaneously

Currently, I have a folder containing 50 mp3 files. My goal is to create an object for each file that includes its name and source.

However, the challenge lies in figuring out how to select and retrieve properties from all of the files. Is this even possible? I am aware that you can extract information from a text file using JS.

A possible approach could be:

for (var i = 0; i < musicFolder.length; i++) {
 var object = new Object (
 musicFolder[i].title,
 musicFolder[i].path/src
 );
 objectArray.push(object);
}

I might need to somehow select an entire folder, but I am unsure how to achieve this in JS.

Answer №1

If you are using Node.js and only want to extract the name and path of a file, you can achieve it like this:

const fs = require('fs');
let filePath = 'enter your file path here';
const fileList = [];
fs.readdir(filePath, (error, files) => {
  for (let i=0; i<files.length; i++) {
    fileList.push({
      fileName: files[i],
      filePath: `${filePath}/${files[i]}`
    });


  }
  console.log(fileList)
});

This code snippet will loop through the specified folder, display all the files it contains, and store each file's name and path in an object before adding it to an array.
