Is it possible to match the # part of a route in React Router 4

问题

In my app, I'd like to match both the path and the hash to different components. For example:

/pageA#modalB

Would show PageA as the main page, with modalB over the top. I've tried the following, with many variations of the path property:

<Route path="#modalB" component={modalB}/>

But nothing works.

In React Router 2 inside a modal 'controller' component, I would use:

browserHistory.listen( (location) => { //do something with loction.hash })

I was hoping for something a little more elegant in V4

Not out of the box, but the beauty of React Router 4 is that it's incredibly easy to implement this yourself.

let HashRoute = ({ component: Component, path, ...routeProps }) => (
  <Route 
    {...routeProps}
    component={({ location, ...props }) =>
      location.hash === path && <Component {...props} />
    }
  />
)

<HashRoute path="#modalB" component={ModalB} />

@azium answer works fine as long as you don't need to use render or children prop in HashRoute. In which case this solution will work better :

import React from 'react';
import { Route } from 'react-router-dom';

const HashRoute = ({ hash, ...routeProps }) => (
  <Route
    render={({ location }) => (
      (location.hash === hash) && <Route {...routeProps} />
    )}
  />
);

export default HashRoute;

Use it like that :

<HashRoute hash="#modalB" component={ModalB} />

Or combine it with route matching :

<HashRoute hash="#modalB" path="/subPageOnly" component={ModalB} />
