Not clear on what you're saying, pseudocode?

  In componentWillUnmount, set a var componentUnmounted true. In componentDidMount in the callback for the fetch, check for componentUnmounted before setting state for an error or whatever you want to do.

    Set a variable... set a property in the component state? Or set a static variable on the class?

      I use a static var on the class. componentDidMount() { if (!this.unmounted) ... } componentWillUnmount() { this.unmounted = true }

        That's not a static car on the class. It's on the instance! A static class property would entail something like `Foo.unmounted = true` (a bad idea).
