JS cache buster

Description
This module adds cache buster '?v=' parameters to your custom javascript files. By default, Drupal adds 'version' parameter of your custom JS library to the request string. However, this is not convenient as you need to bump library version every time you make a tiny change.
If you don't do that, users may be served and obsolete version of the JS file (especially if your website uses CDN).

When you need this module
Usually such a problem does not happen due to JS aggregation, which provides a new filename for the generated JS bundle. But sometimes, you may need to disable aggregation, or you want a specific JS library to be loaded separately (for performance or other reasons).
In that case, this module can help you to resolve cache issues.

Usage
You can use it in the library declaration section, by adding 'enable_buster: true' parameter:

global-scripts:
  version: 1.0
  js:
    js/header_js_not_aggregated.js: {scope: header, enable_buster: true}

Or in the twig template:

<script src="{{ cache_buster('/path/to/js/critical.js') }}"></script>
