Node Electron synch text append

January 10, 2020, at 7:50 PM

I am trying to make an Electron app that will read given directory recursively and print file names to user. Luckily I found a function on GitHub which makes exactly what I want. (Link here).

When function finds files one by one, I want to show user which file has just found.

console.log running fine and I get what I want at exact time. But I don't want users to see developer tools. So I want to print this text somewhere else in DOM.

In this case I added div called show_files and wanted to add texts in this div via Jquery's append function but append function works after everything is done.

I know Node.js working asynchronously but I use everything synchronously in this example. What I am doing wrong or how can I solve this problem?

Code below.

var walkSync = function(dir, fileNameList) {
  var fs = fs || require('fs');
  var path = path || require('path');
  var files = fs.readdirSync(dir);
  fileNameList = fileNameList || [];
  files.forEach(function(file) {
    if (fs.statSync(path.join(dir, file)).isDirectory()) {
      fileNameList = walkSync(path.join(dir, file), fileNameList);
    } else {
      // CHECK HERE -> This runs properly.
      // CHECK HERE -> This runs after everything is done.
      $('#show_files').append(file + "\n");
  return fileNameList;
