Nextjs How To Speedify Root Layout Path for Better Performance

Speeding up your Next.js app's root layout path can make a huge difference in performance.

By default, Next.js uses a fixed path for the root layout, which can lead to slower page loads.

One way to improve performance is to use a dynamic path for the root layout.

This can be achieved by setting the `path` option in the `_app.js` file to a variable that changes based on the route.

The App Router in Next.js 13 introduces a modular approach to routing, enabling features like nested layouts and server components.

This modular approach organizes routes using the folder structure in the app directory, providing better organization and flexibility than the previous file-based routing system.

With the App Router, creating nested layouts is a breeze, and you can compose layouts on a per-page basis to achieve a nested layout.

To create a nested shared layout, you need to nest a new layout that renders the sidebar navigation within the root layout, as shown in the /dashboard/* pages.

Simply wrapping the active route within the root layout only works if you require one layout for the entire application.

You can create a nested shared layout by nesting a new layout that renders the sidebar navigation within the root layout. This is demonstrated in the /dashboard/* pages.

To achieve a nested layout, Next.js provides a way to compose layouts on a per-page basis. This is done by creating a new layout file that exports a component that returns a shared UI for the pages and uses the children prop to render their respective content.

A nested layout is created by applying a getLayout property on the page component and returning the desired layout tree. This is shown in the /dashboard/account.js file where the DashboardLayout is nested within the RootLayout.

The new App Router in Next.js 13 improves routing by enabling features like nested layouts, server components, and streaming. It organizes routes using the folder structure in the app directory, providing better organization and flexibility than the previous file-based routing system.

To create a nested layout for pages under the /dashboard/* route segments, you need to create a new layout file called components/DashboardLayout.js. This file should export a component that returns a shared UI for these pages and uses the children prop to render their respective content.

By applying the getLayout property to the other page components under the /dashboard/* route, you'll also get the desired layout where the state persists between page transitions.
