Node.js recursively list full path of files

I'm having trouble with probably some simple recursive function. The problem is to recursively list all files in a given folder and its subfolders.

For the moment, I've managed to list files in a directory using a simple function:

fs.readdirSync(copyFrom).forEach((file) => {
  let fullPath = path.join(copyFrom, file);

  if (fs.lstatSync(fullPath).isDirectory()) {
    console.log(fullPath);
  } else {
    console.log(fullPath);
  }
});

I've tried various methods like do{} ... while() but I can't get it right. As I'm a beginner in javascript, I finally decided to ask for help from you guys.

Solution

  • Just add a recursive call and you are done:

     function traverseDir(dir) {
   fs.readdirSync(dir).forEach(file => {
     let fullPath = path.join(dir, file);
     if (fs.lstatSync(fullPath).isDirectory()) {
        traverseDir(fullPath);
     }  
     console.log(fullPath);
   });
 }
