React Router - how to constrain params in route matching?

Question

I don\'t really get how to constrain params with, for example a regex.
How to differentiate these two routes?

Answer 1

React-router v4 now allows you to use regexes to match params -- https://reacttraining.com/react-router/web/api/Route/path-string

const NumberRoute = () => 
Number Route
;
const StringRoute = () => 
String Route
;
