This example shows how to build a multi-layout React-router v4 application, assigning different page layouts based on the current route. It defines route wrapper components, `DashboardRoute` and `LoginLayoutRoute`, that wrap their page components inside layout containers using the `render` prop of `Route`. The `BrowserRouter` and `Switch` components manage navigation, while a `Redirect` at the root path sends users to the login page. It uses the `react-router-dom` library to conditionally render a sidebar-based dashboard layout or a minimal login layout.
