Passing props to component in React Router 4

Question

I am new to react-router and I just started writing an app using react-router V4. I would like to to pass props to components rendered by <Match /> and I am wondering about what's the 'best' or 'proper' way to do so.

Is it by doing something like this?

<Match pattern="/" render={
    (defaultProps) => <MyComponent myProp = {myProp} {...defaultProps} />
}/>

Is this (passing props to components to be rendered by <Match />) even a good practice to do so with react-router or is it an antipattern or something; and if so, why?

You must use the render prop instead of component to pass on custom props, otherwise only default Route props are passed ({match, location, history}).

I pass my props to the Router and child components like so.

class App extends Component {

  render() {
    const {another} = this.props
    return <Routes myVariable={2} myBool another={another}/>
  }
}

const Routes = (props) =>
  <Switch>
    <Route path="/public" render={ (routeProps) => 
      <Public routeProps={routeProps} {...props}/>
    }/>
    <Route path="/login" component={Login}/>
    <PrivateRoute path="/" render={ (routeProps) =>
       ...
    }/>
  </Switch>
