Building js file as template to include site menus

I’m using a navigation component in react, with tailwindcss. The component starts with a list of pages, and I was wondering if there is any way to let Hugo populate this list and keep track of the current page.

Looking in the documentation, there is ExecuteAsTemplate | Hugo but won’t the hugo template language mess up the javascript code ?

navigation.jsx

import ReactDOM from 'react-dom/client';
import React, { Fragment } from 'react';

import { Disclosure, Menu, Transition } from '@headlessui/react'
import { Bars3Icon, BellIcon, XMarkIcon } from '@heroicons/react/24/outline'

const navigation = [
  {name: 'Home', href: '/', current: false},
  { name: 'Dashboard', href: '/dashboard/', current: true },
  { name: 'Team', href: '#', current: false },
  { name: 'Projects', href: '#', current: false },
  { name: 'Calendar', href: '#', current: false },
]

function classNames(...classes) {
  return classes.filter(Boolean).join(' ')
}

export default function Navigation() {
  return (
    <Disclosure as="nav" className="bg-gray-800">
      {({ open }) => (
        <>

        </>
      )}
    </Disclosure>
  )
}

const navbar = ReactDOM.createRoot(document.getElementById("navigation"));
navbar.render(<Navigation />);

Ok, I think i figured it out.

On my baseof.html I build the dictionary and pass it to the JSX file:

  {{ $menu := .Site.Menus.main }}
  {{ $navigation := slice }}
  {{- range $menu -}}
      {{ $navigation = $navigation | append (dict "name" .Name "href" .URL "current" false) }}
  {{- end }}
  {{ $navigationJS := resources.Get "js/navigation.jsx" | js.Build (dict "params" (dict "navigation" $navigation)) | babel }}
  <script src="{{ $navigationJS.Permalink }}" integrity="{{ $navigationJS.Data.Integrity }}"></script>

And then on navigation.jsx:

import { navigation } from '@params';

const currentPath = window.location.pathname;
const navigationMenu = navigation.map(item => ({
  ...item,
  current: item.href === currentPath,
}));

// ... //

<div className="flex space-x-4">
  {navigationMenu.map((item) => (
    <a
      key={item.name}
      href={item.href}
      className={classNames(
        item.current ? 'bg-gray-900 text-white' : 'text-gray-300 hover:bg-gray-700 hover:text-white',
        'rounded-md px-3 py-2 text-sm font-medium'
      )}
      aria-current={item.current ? 'page' : undefined}
    >
      {item.name}
    </a>
  ))}
</div>

Is this the right way to do it?
