props history
class Comp extends React.Component {
componentDidUpdate(prevProps) {
// will be true
const locationChanged =
this.props.location !== prevProps.location;
// INCORRECT, will *always* be false because history is mutable.
const locationChanged =
this.props.history.location !== prevProps.history.location;
}
}
<Route component={Comp} />;
