NavBar + Hamburger Menu w/ Active Link Styling in Next.js 13

This gist is a guide for setting up a navigation bar (with working hamburger menu) and active link styling in Next.js 13.
(it assumes you have already installed version 13+ of Next.js)

Updating your navbar from a previous version of Next.js should be fairly straightforward - all queries that arise during this process should be directed to the (excellent) Next.js 13 beta docs.

I have used "TODO" markers to indicate the sections that require updates for your specific application.

Regarding styling, CSS modules are used but you can easily find all/replace instances of ".style" and update to other styling methods.

JSX Code

Navbar.jsx

"use client";
import styles from "./NavBar.module.css"; // CSS module import
import { useState } from "react";

import Image from "next/image";
import exampleImg from "./assets/example.png"; // TODO: replace image import

import Link from "next/link";
import { usePathname } from "next/navigation";

export function NavBar() {
	const pathname = usePathname(); // this replaces Next <12 useRouter() and the property "asPath"

  // logic for hamburger menu
	const [hamOpen, setHamOpen] = useState(false);
	const hamburgerMenuToggle = () => {
		setHamOpen(!hamOpen);
	};
	const closeMenu = () => {
		setHamOpen(false);
	};

	return (

CSS Code

Notes:

1. Provided colors are basic and should be replaced
2. CSS is mobile-first, so media queries define behavior PAST the defined pixel amount (600px to start)
