If like us you develop Web applications and deploy them on Linux servers (development or production environments), you might have wondered how to handle file permissions on the application files in a simple and fool-proof way.
Some facts

Developers operating on the server require specific file permissions on the application files to be able to read and write them (for obvious reasons).
The web server (Apache, nginx, Lighttpd, etc.) also requires specific file permissions on the application files to be able to read them, and for some files (but not all files), to be able to write them (like for instance, when uploading a file, or creating a thumbnail, etc.)

  
## domParamNormalizer.js
import isSelectorValid from './isSelectorValid';

export default (param) => {
  switch (true) {
    case isSelectorValid(param):
      return document.querySelectorAll(param);
    case param instanceof HTMLElement:
      return [param];
    case param instanceof NodeList:
    case param instanceof HTMLCollection:

## isSelectorValid.js
const queryCheck = (s) => document.createDocumentFragment().querySelector(s);

export default function isSelectorValid(selector) {
  if (typeof selector !== 'string') return false;
  try { queryCheck(selector); } catch { return false; }
  return true;
}

## getLabelTextFromField.js
function getLabelTextFromField(formElement) {
  return formElement.ariaLabel
  || formElement.labels?.[0]?.textContent;
}

To make Pageant automatically run and load keys at startup:

- Windows key + R to open the 'run' dialog box

- Type: 'shell:startup' in the dialog box

- Create a shortcut to the pageant.exe and put into this startup folder.
