How to load icons dynamically in Next.js?

I have these lines in my Next.js / React files:

import { FontAwesomeIcon } from "@fortawesome/react-fontawesome";

Based on the docs: https://nextjs.org/docs/advanced-features/dynamic-import

I replaced with this:

import dynamic from "next/dynamic";
const FontAwesomeIcon = dynamic(() => import("@fortawesome/react-fontawesome"));

And I kept these lines:

<FontAwesomeIcon icon={icon} className={styles.icon} />

but compiler yarn build raise error refering some Promise issue

Do you know maybe what is wrong?

Solution

With

const FontAwesomeIcon = dynamic(() => import("@fortawesome/react-fontawesome"));

you are insinuating the default export of @fortawesome/react-fontawesome is a component that could be made dynamic, but with

import { FontAwesomeIcon } from "@fortawesome/react-fontawesome";

you are importing the named export FontAwesomeIcon.

The dynamic equivalent of that import would be

const FontAwesomeIcon = dynamic(async () => {
  const mod = await import("@fortawesome/react-fontawesome"));
  return mod.FontAwesomeIcon;
});

or in other words

const FontAwesomeIcon = dynamic(async () => {
  const {FontAwesomeIcon} = await import("@fortawesome/react-fontawesome"));
  return FontAwesomeIcon;
});

const FontAwesomeIcon = dynamic(async () => (
  (await import("@fortawesome/react-fontawesome")).FontAwesomeIcon
));
