Base_url as a default value in a custom Config file

@sevmusic,
>>> Is getting the base_url() possible as a default value in a Config file?

Perhaps consider defining the CONST in index.php and it will be available throughout the application:

file:  /index.php

PHP Code:

# DYNAMIC PATH ===================================================
  # dynamic BaseUrl - https://forum.codeigniter.com/thread-74649.html  
  if( TRUE || DEFINED('AUTOMATIC_URL_DETECTION') ) :
    $url = (isset($_SERVER['HTTPS']) && !empty($_SERVER['HTTPS']) 
        && 
        ('on' == $_SERVER['HTTPS']) 
        ? "https://" 
        : "http://") .$_SERVER['HTTP_HOST']
        ;
    $url .= str_replace
    (
      basename($_SERVER['SCRIPT_NAME']), 
      '', 
      $_SERVER['SCRIPT_NAME']
    );
  endif;  
  defined('BASE_URL') ?: define('BASE_URL', $url); # app/Paths.php, etc
# DYNAMIC PATH =================================================== 


[
file: app/Config/App.php

PHP Code:

  public $baseURL = BASE_URL; // http://localhost:8080/';
