[Q] RecoilStateInfo.subscribers.components.name is "<component name not available>"

[mtablo]

Hi there,
I'm implementing some kind of devtool.

  const getInfo = useGetRecoilValueInfo_UNSTABLE();
  const info = getInfo(someAtomOrSelector);
  console.log(Array.from(info.subscribers.components));

With this code, I got something like

[
    {
        "name": "<component name not available>"
    },
    {
        "name": "<component name not available>"
    },
    {
        "name": "<component name not available>"
    }
]

It seems the count of the array is correct, but I couldn't get the components' names.
All of my components are type of (...) => JSX.Element.
How can I get the component name properly?

EDIT; recoil version
"recoil": "^0.5.2"

Same here, with the latest (0.7.4), and in fact, I also get an empty array trying to look at the values as well, following the code right from the docs:

const getRecoilValueInfo = useGetRecoilValueInfo_UNSTABLE();
const {subscribers} = getRecoilValueInfo(myAtom);
console.debug(
      'Current Subscriber Nodes:',
      Array.from(subscribers.nodes).map(({key}) => key),
    );

Is there some trick about where we need to place this code or something?

The React component name logic was removed due to performance concerns. Help wanted for a better approach to get this.

@drarmstr ok, that explain why components is empty, but should nodes still work?

Yes, it should.

@drarmstr ok, thank you for confirming, and I can confirm nodes does work, the recoil docs use console.debug and apparently the default logging levels in chrome don't include "verbose" which is what is needed to see the debug level logs 🤦‍♂️
