The following 2 errors was displayed at interface NextLinkComposedProps on VSCode

Interface 'NextLinkComposedProps' cannot simultaneously extend types 'Omit<AnchorHTMLAttributes<HTMLAnchorElement>, "href">' and 'Omit<InternalLinkProps, "href" | "as">'.
  Named property 'onClick' of types 'Omit<AnchorHTMLAttributes<HTMLAnchorElement>, "href">' and 'Omit<InternalLinkProps, "href" | "as">' are not identical. ts(2320)

Interface 'NextLinkComposedProps' cannot simultaneously extend types 'Omit<AnchorHTMLAttributes<HTMLAnchorElement>, "href">' and 'Omit<InternalLinkProps, "href" | "as">'.
  Named property 'onMouseEnter' of types 'Omit<AnchorHTMLAttributes<HTMLAnchorElement>, "href">' and 'Omit<InternalLinkProps, "href" | "as">' are not identical. ts(2320)

The following are candidates for correction

Thanks for the suggestion @alecriarstudio

I've updated this gist for anyone, but the official version is at https://github.com/mui/material-ui/tree/master/examples/nextjs-with-typescript

You might send a PR to the MUI repo to adapt your suggestion as well.

With the update brought by Next13 we're able to simplify the next/link + mui link/button process a lot:

import { Button, ButtonProps } from '@mui/material'
import NextLink from 'next/link'

export default function LinkButton(props: ButtonProps<'a'>) {
  return <Button component={NextLink} {...props} />
}

import { LinkProps, Link as MuiLink } from '@mui/material'
import NextLink from 'next/link'

export default function Link(props: LinkProps<'a'>) {
  return <MuiLink component={NextLink} {...props} />
}

Thanks @kachar

Latest approach is indeed simple but we are not able to pass href as an object. It only accepts string type. Given that NextLink accepts a URL object as href, how can we get same behaviour here?

@vighnesh153 I've tried to make it work with LinkProps['href'] but the MuiButton expectation is a hardcoded { href: string } so I don't think it's currently possible:

// node_modules/@mui/material/Button/Button.d.ts

export type ExtendButton<M extends OverridableTypeMap> = ((
  props: { href: string } & OverrideProps<ExtendButtonBaseTypeMap<M>, 'a'>,
) => JSX.Element) &
  OverridableComponent<ExtendButtonBaseTypeMap<M>>;

What I end up doing in multiple projects is having a general routes.ts file that contains all the app links as follows:

export const routes = {
  post: {
    byId: (id: string) => `/post/${id}`,
  }
}

and use it as:

<LinkButton color="secondary" variant="contained" href={routes.post.byId(query.id)}>
  View post
</LinkButton>
