Hi @winged stream. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

To use your layout.tsx across the entire web app without designing the layout for each route, you can create a Custom App and wrap your application with the layout. Since the <Layout /> component is re-used when changing pages, its component state will be preserved (e.g., input values).

Create a _app.tsx file inside the pages directory and wrap your application with the layout:

// pages/_app.tsx

import Layout from '../app/layout'

export default function MyApp({ Component, pageProps }) {
  return (
    <Layout>
      <Component {...pageProps} />
    </Layout>
  )
}

This will apply the Layout component to all pages in your application, reusing the code and preserving the component state across navigations source (https://nextjs.org/docs/basic-features/layouts#single-shared-layout-with-custom-app).

Note: you can ask me a follow up question by @ mentioning me again :speech_balloon:

Create your first page and shared layout with the Pages Router.

Let me check the knowledge base for you. One moment! :books:

I apologize for the confusion. In Next.js 13 with the app directory, you should define your global layout in the root layout file (app/layout.tsx). The root layout will apply to all routes inside the app directory.

Here's an example of how to create a root layout in app/layout.tsx:

// app/layout.tsx

export default function RootLayout({
  children,
}: {
  children: React.ReactNode;
}) {
  return (
    <html lang="en">
      <body>{children}</body>
    </html>
  );
}

By defining your layout in app/layout.tsx, it will be applied to all routes inside the app directory source (https://beta.nextjs.org/docs/routing/pages-and-layouts#root-layout).

If you want to apply global styles, you can import them directly into the root layout file (app/layout.tsx). For example, if you have a global.css file:

// app/global.css

body {
  padding: 20px 20px 60px;
  max-width: 680px;
  margin: 0 auto;
}

Import the global.css stylesheet in app/layout.tsx:

// app/layout.tsx

import './global.css';

export default function RootLayout({ children }: {
  children: React.ReactNode;
}) {
  return (
    <html lang="en">
      <body>{children}</body>
    </html>
  );
}

This will apply the global styles to every route in your application source (https://beta.nextjs.org/docs/styling/global-styles).
