Outlets

Outlets are a powerful feature of the file-system based router that allows you to create nested layouts and reuse components in your app. You can add outlets to your layouts by defining routes in a subdirectory of your layout with a name starting with @. When the route under your outlet directory matches the URL, the component exported from that route definition file will be passed as a React prop to your layout component.

// (main).layout.jsx

export default function RootLayout({ sidebar, children }) {
  return (
    <main>
      {sidebar}
      {children}
    </main>
  );
}

export default function Sidebar() {
  return <aside>...</aside>;
}

To make outlets available for client-side navigation, you can use the ReactServerComponent component from the @lazarv/react-server/navigation module. But using the file-system based router, the server-side rendering is handled automatically for each outlet. You can fine-tune the navigation of your app by using the Link and Refresh components from the same module when using outlets. Combining an initial content using the outlet available as the prop in your layout component and client-side navigation with the ReactServerComponent component, you can create a powerful navigation system for your app.

import { ReactServerComponent } from "@lazarv/react-server/navigation";

export default function RootLayout({ sidebar, children }) {
  return (
    <main>
      <ReactServerComponent outlet="sidebar">
        {sidebar}
      </ReactServerComponent>
      {children}
    </main>
  );
}
