Server-side Rendering React + Redux, how to pass parameters?

Question

React

Hello. There was a question about the server rendering of the stack from REACT and REDUX.
Loading data like this:

/Component.jsx
...
static initialAction() { 
  return dispatch => { 
     axios.post('url')
     .then(res => res.data)
     .then(data=>dispatch({type: 'SET_TEST', test: data}))
     .catch(e=>console.log(e)); 
  }
}
...

On the server it looks like this:

/server.js
...
const promises = routes.reduce((acc, route) => { 
  if (matchPath(req.url, route) && route.component && route.component.initialAction){
     acc.push(Promise.resolve(store.dispatch(route.component.initialAction()))); 
  } 
  return acc; 
}, []);
Promise.all(promises).then(()=>{
//Вся морока с рендером
});
...

route.component.initialAction()- this is the function above
Everything works as it should, but let's say I need to render a dynamic page. How to pass parameter to this static function? Parameter from a line it is natural.
Parsing is an option req.url, but would that be the right solution?
