Why are you all talking about the "reject option", which implicitly considers the opt-in to be the default? The default MUST be the opt-out (for non-essential cookies), hence there is no "reject" because there must be the "accept".
You can be forced to choose, i.e. you can be presented with a popup. And that popup should have both a reject (opt-out) and an accept (opt-in) option. Well, the latter is not needed but otherwise it wouldn't make sense.
Now a lot of sites play tricks to make the reject/out-out a hard deliberately choice. (Which IS a violation of the GDPR, of course.)
(author here) Very good point(s) and thank you for the input! Treenee is indeed very minimal and it's supposed to be working basically "out-of-the-box". This also means that some features are obviously missing at the moment.
I use Treenee internally (even though I wanted to keep it on m y own name, not the company's) and I decided to put it out there as soon as it was "complete". I will add more examples and use cases in the near future (also screenshots, but I am a bit ashamed of the scarce "design").
Do you mind expanding a bit on what you would like "logging" to be?
I agree that this heavily opinionated "starter kit" might be not what you want to give to a beginner (also it feels quite obsolete nowadays), but I quite disagree that create-react-app is a better choice.
I think that CRA is either useless as it is too simple and confusing (in its first run, before you "eject"... what are those react scripts, for example?) or too far away down the road of "choose what technique is best for your project" once you "eject".
I rather consider using a "true" starter kit, with no helpers and not many applied opinions to it (like, no redux for example and/or no decision on how to handle CSS). With this principle in mind, I wrote my starter kit https://github.com/claudioc/react-with-typescript-starterkit (yes, there are many of them already, but I try for it to be a middle ground between something that you want to use to bootstrap an real new app and something you study to learn the _what_ you need to start and begin by yourself).
