fs read directory code example

Example 1: node list files in directory

//requiring path and fs modules
const path = require('path');
const fs = require('fs');
//joining path of directory 
const directoryPath = path.join(__dirname, 'Documents');
//passsing directoryPath and callback function
fs.readdir(directoryPath, function (err, files) {
    //handling error
    if (err) {
        return console.log('Unable to scan directory: ' + err);
    } 
    //listing all files using forEach
    files.forEach(function (file) {
        // Do whatever you want to do with the file
        console.log(file); 
    });
});

Example 2: node js get files in dir

    if (err) throw err;
    
    for (let file of files) {
      console.log(file);
    }
  }
);
