How to Compose Next 13 Link and MUI Link (with Typescript)

Hello, hustler! NextJS recently released a major update which is Next 13, It included an update to the critical next/link component.  In this tutorial, you'll learn how to customize the MUI Link component and integrate the behavior of the next/link component and fix the naming conflict of the href prop of both components.

Introduction #

NextJS and MUI are a very common combination for front-end development and it speeds up the development time by a lot. When NextJS released version 13, I found it difficult to customize the MUI Link with next/link. I was able to figure out two ways to achieve the desired behavior. 

The techniques shown here can be used not only for the next/link component but when creating any other custom components as well. 

Scope of this Tutorial #

We limit this tutorial to the following versions:

  • MUI version 5.x and up
  • NextJS version 13.x and up

Way #1 - Using the component Property of MuiLink #

If you don't need to create a custom component you can directly use the component property of MuiLink, but it's not without its drawbacks. For example:

import { Link as MuiLink } from "@mui/material";
import NextLink from "next/link";
const Container = () => {
  return (
    <div>
      {/* This will use "prop forwarding" and MuiLink will automatically have the props of NextLink */}
      <MuiLink component={NextLink} prefetch={false} href={"/page1"}>
        hello
      </MuiLink>
      {/* However, passing a URLObject in href results in a type error */}
      <MuiLink
        component={NextLink}
        prefetch={false}
        href={{ pathname: "/page1" }} //type error
      >
        hello
      </MuiLink>
    </div>
  );
};
export default Container;

This pattern will use prop forwarding and MuiLink will automatically get the NextLink props.  But since both MuiLink and NextLink have href props, this causes name collisions and results in a type error. It will use the href prop from MuiLink.

Way #2 - Modifying NextLink href Property #

To solve the problem above, you can extend the NextLink component and rename the href prop to something else to avoid naming collisions. Here's how to do it in Typescript.

// components/MyLink.tsx
import { LinkProps, Link as MuiLink } from "@mui/material";
import NextLink, { LinkProps as NextLinkProps } from "next/link";
// Defining the CustomNextLink
export type CustomNextLinkProps = Omit<NextLinkProps, "href"> & {
  _href: NextLinkProps["href"];
};
export const CustomNextLink = ({ _href, ...props }: CustomNextLinkProps) => {
  return <NextLink href={_href} {...props} />;
};
// combine MUI LinkProps with NextLinkProps
type CombinedLinkProps = LinkProps<typeof NextLink>;
// remove both href properties
// and define a new href property using NextLinkProps
type MyLinkProps = Omit<CombinedLinkProps, "href"> & {
  href: NextLinkProps["href"];
};
const MyLink = ({ href, ...props }: MyLinkProps) => {
  // use _href props of CustomNextLink to set the href
  return <MuiLink {...props} component={CustomNextLink} _href={href} />;
};
export default MyLink;

Explanation:
Line 5-10: We define the component CustomNextLink that uses _href prop to avoid naming collisions. This is an internal component for this file and is not to be used anywhere else.

Line 12-17: We take a roundabout way to remove the href props and define a new href prop that uses the one NextLinkProps for our custom MuiLink component.

Line 20: Here's where the magic happens. We use the _href props from our CustomNextLink and pass the next href prop that we just defined on line 16.

Perhaps there's a better way of defining the MyLinkProps, but I found this to be really easy to digest.

Usage:

import MyLink from "./MyLink";
// MyLink usage
const Container2 = () => {
  return (
    <div>
      <MyLink
        prefetch={false}
        scroll={false}
        sx={{ color: "warning.main" }}
        href={{ pathname: "/page1" }}
      >
        hello
      </MyLink>
      <MyLink
        prefetch={false}
        scroll={false}
        sx={{ color: "warning.main" }}
        href="/page2" //Both string and URLObject are accepted
      >
        hello
      </MyLink>
    </div>
  );
};
export default Container2;

Here we can see that it's a very seamless integration with NextLink and MUILink. I think this is a very good pattern to know.

Usage with styled:

If you want to use styled components, you can use the new wrapper component as the base:

// components/StyledLink:
import { styled } from "@mui/material/styles";
import MyLink, { MyLinkProps } from "./MyLink";

const StyledLink = styled(MyLink)<MyLinkProps>({});
StyledLink.defaultProps = {
  color: "seagreen",
  underline: "hover",
};
export default StyledLink;

Conclusion #

We learned how to integrate next/link with MUI Link component by creating a custom component and modifying the default props to avoid naming collisions. I think this is a very important pattern to learn and master, and you can apply it in other MUI components as well.
