Is there a way to console log whenever a component is rendered or re-rendered?

I have a suspicion that my React app is re-rendering a lot of components due to some unknown errors in my code. I want to be made aware each time any of my components re-render.

I can go into each component and add a console log at the top of each render method but that would be time consuming since there are a lot of components and I would have to do this each time I add a new one.

Is there any "catch all middle-ware" that can be run right before any React component is about to render/re-render? One that sit's globally in one place and works for all components across the board?
