Is there any roadmap to enable the detection of iframes in React devtools? about react

That's the actual point here, yes.

The React DevTools add window.__REACT_DEVTOOLS_GLOBAL_HOOK__ to the main window, but not to iframes.

So, you have to copy that reference into each iframe in order for the DevTools to talk to React inside that iframe.

See #18945 for the main discussion around iframe handling.

Most likely you'll need to do something like this:

if (window.parent) {
  window.__REACT_DEVTOOLS_GLOBAL_HOOK__ = window.parent.__REACT_DEVTOOLS_GLOBAL_HOOK__;
}

Thanks for sharing @markerikson. I didn't knew there was an already open discussion about it, I should close this issue then 😅

Actually, for me it's the other way around, something like:

const iframeWindow = ocument.getElementById("iframe").contentWindow;
if(iframeWindow){
  window.__REACT_DEVTOOLS_GLOBAL_HOOK__ = iframeWindow.__REACT_DEVTOOLS_GLOBAL_HOOK__ 
}

but iframeWindow.__REACT_DEVTOOLS_GLOBAL_HOOK__ is undefined so I guess the React Devtools doesn't inject __REACT_DEVTOOLS_GLOBAL_HOOK__ into iframes.

Ah I see!

I just tested it but in my case the Iframe runs on different domains (I inject the Iframe from an extension) I get a cross-origin error.

Thanks for your help!
