Set the default preference to 'allow' or 'deny' for each service

Hello @Mr. Lewis,

sorry, I'm late with my answer. But may be it will help someone else.
You know this is a queer request, but it is your responsibillity that all is in terms of the GDPR.

My recommended solution

This is the core of a javascript you will need. It will set the services "my_service" and "xy_service" to "allow".
(You can execute the code from every JS file you want. You don't need a fork or somthing. Just create a custom Drupal css/js library with a dependency: "cookies/cookiesjsr". This ensures the event listener is present.)

var services = {
  'my_service': true,
  'xy_service': true,
}
document.dispatchEvent(
   new CustomEvent('cookiesjsrSetService', {detail: { services }})
);

WARNING: Just set services, you want to enable. The other services are denied by default. Because: If you set all existing services, the COOKiES consent banner will not come up.

This code has to be wrapped into other code that ensures that this function is only executed once at the beginning of the session and not for every page view.
I would recommend to check, if the cookie with the name cookiesjsr IS_NOT present THEN execute code above.
(To check if the cookie "cookiesjsr" exists, you can use e.g. the JS/CSS library "core/js-cookie" as an other dependency.)

// Don't know if this is correct. 
if(typeof cookies.get("cookiesjsr") !== 'object') {
   // code above here.
}

All in all just 10 lines of code and you are done.

Hey ho, let's go! 2.x branch was recently created. Please help to implement this or if you're not a developer, please sponsor some development hours.

I'm really now putting effort to see what is going on here. So this module "COOKiES Consent Management" (https://www.drupal.org/project/cookies) is under "GNU General Public License, version 2". Now, my question is, why this module includes JS code that has been minifed and is not easily human-readable? This is in violation of GNU General Public License, version 2. Also, mr. @anybody mentions sponsoring of development of the module in one of the previous posts. So, we have closed (non-human readable JS code) that is crucial for this module to work and we have sponsoring ideas. Blink blink?

@orcalator I have no idea which personal problems you have, but let me tell you why this escalated.

This is a community project and all the maintainers put in weeks of their spare time. You came here, not trying to help with any kind of fix, like a patch or MR, just being unfriendly and offensive. Why are you wondering about such reactions?

You're still not trying to help in any positive way. It's very simple: Help yourself and the community by debugging this issue and providing helpful information to fix it. You would have immediately got help and assistance, if you did that.

Still no idea why. And no, I'm sorry to tell you that this is not a violation of GNU, the included library in 2.x is also under GNU: https://github.com/jfeltkamp/cookiesjsr and written by the original maintainer of COOKiES. It's just minified as best practice for faster loading.

You should ask yourself, why you're so frustrated and putting that much power into negativity. I'm honestly sorry for that.
And I should ask myself why I'm still taking the time to reply to such trolling comments.

PS: Nobody here earned a cent with this, just to let you know ;)

PPS: Just calm down and try to help to improve things. That would be great! (Power of positivity!)

The GNU General Public License says the source code must be available, not that code cannot be minified.
This is not even the case, since the source code is available on https://github.com/jfeltkamp/cookiesjsr.

Thanks @avpaderno and it's not even included, but an external library.
