Pass custom data to PrivateRoute component in React

You need to pass on the ...rest params that you pass to PrivateRoute on to the component, however not all of them need to react the component. You can destructure other params that are needed by React router

const PrivateRoute = ({ component: Component, exact, strict, path, ...rest }) => (
  <Route
    exact={exact}
    strict={strict}
    path={path}
    render={props =>
      fakeAuth.isAuthenticated ? (
        <Component {...props} {...rest} />
      ) : (
        <Redirect
          to={{
            pathname: "/login",
            state: { from: props.location }
          }}
        />
      )
    }
  />
);
