My goal is to encapsulate the _app.js file within a custom layout, similar to what I have done before. This way, I can include a Navbar at the top and wrap everything else within a container:
//layout.js file
import { Container } from 'react-bootstrap';
import Navbar from './Navbar';
export default function Layout(props) {
return (
<>
<Navbar />
<br />
<Container>
{props.children}
</Container>
<br />
</>
)
}
// _app.js file
import '@/styles/bootstrap.min.css';
import "@/styles/globals.css";
import Layout from "@/components/Layout";
import { SWRConfig } from "swr";
export default function App({ Component, pageProps }) {
return (
<>
<Layout>
<SWRConfig
value={{
fetcher: async (url) => {
const res = await fetch(url);
// If the status code is not in the range 200-299,
// we still try to parse and throw it.
if (!res.ok) {
const error = new Error(
"An error occurred while fetching the data."
);
// Attach extra info to the error object.
error.info = await res.json();
error.status = res.status;
throw error;
}
return res.json();
},
}}
>
<Component {...pageProps} />
</SWRConfig>
</Layout>
</>
);
}
In Next.js 13, the layout.js file inside the app folder has been updated as follows:
import './globals.css'
import { Inter } from 'next/font/google'
import Navbar from '@/components/Navbar';
const inter = Inter({ subsets: ['latin'] })
export const metadata = {
title: 'Create Next App',
description: 'Generated by create next app',
}
export default function RootLayout({ children }) {
return (
<html lang="en">
<body className={inter.className}><Navbar /><br />{children}</body>
</html>
)
}
When attempting to incorporate the HTML snippet with the layout component, like so:
import './globals.css'
import { Inter } from 'next/font/google'
import Navbar from '@/components/Navbar';
const inter = Inter({ subsets: ['latin'] })
export const metadata = {
title: 'Create Next App',
description: 'Generated by create next app',
}
export default function RootLayout({ children }) {
return (
<Layout> <html lang="en">
<body className={inter.className}><Navbar /><br />{children}</body>
</html>
</Layout>
)
}
This results in a hydration error. Could you also provide an explanation of the hydration error in simple terms with examples? Any assistance would be greatly appreciated.
