How to download automatically all folders with nodejs in azure?

Question

JavaScript

You need to test one function, for this you need this functionality. Thanks for the help.
There is a piece of code that shows all folders in the C: ILJATEST directory

var dirPath = path.join("C:\\", 'ILJATEST');
    fs.readdir(dirPath, function (err, files) {
        if (err) {
            return console.log('Unable to scan dir ' + err);
        }
        files.forEach(function (file) {

            console.log(file);
        });
    });

There is also a working code that, after selecting a file and clicking on the button, uploads the file to the server. Here's the part that does it:

document.getElementById('upload-button').addEventListener('click', () => {
            const file = document.getElementById('fileinput').files[0];
            blobService.createBlockBlobFromBrowserFile('mycontainer',
                file.name,
                file,
                (error, result) => {
                    if (error) {
                        // Handle blob error
                    } else {
                        console.log('Upload is successful');
                    }
                });
        });

How to combine them so that when the application is launched, all folders from this directory are automatically uploaded to the server?
