How do you inspect a react element's props & state in the console?

Using React Developer Tools you can use $r to get a reference to the selected React Component.

The following screenshot shows you that I use React Developer Tools to select a component (Explorer) which has a state-object callednodeList. In the console I can now simply write $r.state.nodeList to reference this object in the state. Same works with the props (eg.: $r.props.path)

An answer to your question can be found here in a similar question I asked: React - getting a component from a DOM element for debugging

I'm providing an answer here because I don't have the necessary reputation points in order to mark as duplicate or to comment above.

Basically, this is possible if you are using the development build of react because you can leverage the TestUtils to accomplish your goal.

You need to do only two things:

  • Statically store the root level component you got from React.render().
  • Create a global debug helper function that you can use in the console with $0 that accesses your static component.

So the code in the console might look something like:

> getComponent($0).props

The implementation of getComponent can use React.addons.TestUtils.findAllInRenderedTree to search for match by calling getDOMNode on all the found components and matching against the passed in element.


Open console (Firefox,Chrome) and locate any reactjs rendered DOM element or alternatively execute js script to locate it:

document.getElementById('ROOT')

Then check for element properties in object property viewer for attributes with name beginning like '__reactInternalInstace$....' expand _DebugOwner and see stateNode.

The found stateNode will contain (if it has) 'state' and 'props' attributes which is used heavily in reactjs app.
