viewport setting in metadata is not working correctly about next.js

[ttaerrim]

Sorry, I deleted my comment by mistake.

try to add code to root layout.tsx

export const viewport: Viewport = {
  width: 1920
}

But I don't know how to initialize viewport tag to none.

Hi, initial-scale set to 1 will not harm since it is the default value.
Since the default value is mapped internally, you cannot explicitly remove it from your source.

next.js/packages/next/src/lib/metadata/default-metadata.tsx

Lines 6 to 15 in 65d699e

	export function createDefaultViewport(): ResolvedViewport {
	return {
	// name=viewport
	width: 'device-width',
	initialScale: 1,
	// visual metadata
	themeColor: null,
	colorScheme: null,
	}
	}

Also, it is recommended to follow the Codemods so that you don't need to explicitly export viewport.

I recently upgraded vercel version and didn't realize that the viewport for metadata was deprecated. Thanks for letting me know🙏 @ttaerrim

When I applied it as you suggested, it looks like <meta name="viewport" content="width=1920, initial-scale=1">, but can't I remove the ,initial-scale=1?

Actually, what I'm working on now is to show the desktop in 1920 width on the mobile screen. Before upgrading nextjs, it was <meta name="viewport" content="width=1920" /> and it worked as I wanted, but now it doesn't work when it's set to <meta name="viewport content="width=1920, initial-scale=1" />.

The default value of initial-scale is 1, but I figured that its presence had an impact, so I set initial-scale to -1 and it worked fine.

Thank you for your kind explanation and help in resolving the issue.
