In Index.re, let's wrap <App /> within a router component that provides the currentRoute prop:

ReactDOMRe.renderToElementWithId(  <Router.WithRouter>    ...((~currentRoute) => <App currentRoute />)  </Router.WithRouter>,  "root",);

In Router.re, we define three components—<WithRouter />, <Link />, and <NavLink />—using the module syntax. Since each file is also a module, those three components are nested under the Router module, and in Index.re we need to tell the compiler to look for <WithRouter /> within the Router module:

module WithRouter = {  type state = route;  type action =    | ChangeRoute(route);  let component = ReasonReact.reducerComponent("WithRouter");  let make = children => {    ...component,    didMount: self => { let watcherID ...
