How can I count the number of files in a directory using nodejs
with just plain JavaScript or packages? I want to do something like this:
How to count the n
1) Download shell.js and node.js (if you don't have it)
2) Go where you download it and create there a file named countFiles.js
var sh = require('shelljs');
var count = 0;
function annotateFolder (folderPath) {
sh.cd(folderPath);
var files = sh.ls() || [];
for (var i=0; i<files.length; i++) {
var file = files[i];
if (!file.match(/.*\..*/)) {
annotateFolder(file);
sh.cd('../');
} else {
count++;
}
}
}
if (process.argv.slice(2)[0])
annotateFolder(process.argv.slice(2)[0]);
else {
console.log('There is no folder');
}
console.log(count);
3) Open the command promt in the shelljs folder (where countFiles.js is) and write node countFiles "DESTINATION_FOLDER"
(e.g. node countFiles "C:\Users\MyUser\Desktop\testFolder"
)
