Hi @worthy ibex. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
To perform a redirect based on the device type (desktop or mobile), you can use the userAgent helper from Next.js. This helper extends the Web Request API with additional properties and methods to interact with the user agent object from the request.
Here's how you can modify your code to perform a redirect if the device type is desktop:
import { NextResponse, userAgent } from 'next/server';
import type { NextRequest } from 'next/server';
export function middleware(request: NextRequest) {
// Parse user agent
const { device } = userAgent(request);
// Check the viewport
const viewport = device.type === 'mobile' ? 'mobile' : 'desktop';
// If the viewport is desktop, redirect to the desktop view
if (viewport === 'desktop') {
request.nextUrl.pathname = '/desktop/view';
return NextResponse.rewrite(request.nextUrl);
}
// If the viewport is mobile, do not perform a redirect
return NextResponse.next();
}
This code uses the userAgent helper to parse the user agent from the request and determine the device type. If the device type is 'desktop', it rewrites the request URL to '/desktop/view' and returns a rewritten response. If the device type is 'mobile', it does not perform a redirect and returns the original response.
Please note that this code should be placed in a middleware file at the root of your project or in the src directory if you are using it.

@bright jackal i would like the function perform at page.tsx instead of middleware

Let me check the knowledge base for you again. Give me one moment! :books:
To perform a redirect based on the device type (desktop or mobile) directly in a page component, you can use the window object to access the viewport width. However, keep in mind that this approach will only work on the client-side because the window object is not available on the server-side.
Here's how you can modify your code to perform a redirect if the viewport width is greater than a certain value (indicating a desktop device):
import { useEffect } from 'react';
import { useRouter } from 'next/router';
export default function Page() {
const router = useRouter();
useEffect(() => {
// Check the viewport width
const viewportWidth = window.innerWidth;
// If the viewport width is greater than 768px, redirect to the desktop view
if (viewportWidth > 768) {
router.push('/desktop/view');
}
}, []);
// Render the mobile view
return (
// Your mobile view code here...
);
}
This code uses the useEffect hook to run a function after the component has been rendered. Inside this function, it checks the viewport width using window.innerWidth. If the viewport width is greater than 768px (indicating a desktop device), it performs a redirect to '/desktop/view' using router.push.
Please note that this code should be placed in your page.tsx file.
