How to use vanta with nextjs?
Question
I am trying to use vanta with next.js, following this guide . It works completely fine with the Net Effect, however, when I try to use the Globe Effect, I get
[VANTA] Init error TypeError: r.Geometry is not a constructor
at h.onInit (vanta.globe.min.js:1)
at h.init (vanta.globe.min.js:1)
at new r.VantaBase (vanta.globe.min.js:1)
at new h (vanta.globe.min.js:1)
at r.<computed> (vanta.globe.min.js:1)
I have isolated Vanta into an Background Component
//Background.js
import { useState, useRef, useEffect } from "react";
import NET from "vanta/dist/vanta.globe.min"
import * as THREE from "three";
export default function Background({ width, height, children }) {
const [vantaEffect, setVantaEffect] = useState(0);
const vantaRef = useRef(null);
useEffect(() => {
if (!vantaEffect) {
setVantaEffect(
NET({
THREE,
el: vantaRef.current,
})
);
}
return () => {
if (vantaEffect) vantaEffect.destroy();
};
}, [vantaEffect]);
return (
<div ref={vantaRef}>{children}</div>
)
}
And added the THREE script into my _app.js
import '../styles/globals.css'
import Head from "next/head";
import Navbar from "../components/Navbar";
import { useEffect } from "react";
export default function App({ Component, pageProps }) {
useEffect(() => {
const threeScript = document.createElement("script");
threeScript.setAttribute("id", "threeScript");
threeScript.setAttribute(
"src",
"https://cdnjs.cloudflare.com/ajax/libs/three.js/r121/three.min.js"
);
document.getElementsByTagName("head")[0].appendChild(threeScript);
return () => {
if (threeScript) {
threeScript.remove();
}
};
}, []);
return (
<>
<Head>
<title>BrainStorm Tutoring</title>
</Head>
<Navbar />
<Component {...pageProps} />
</>
)
}
and used it like so
//index
import Background from "../components/Background";
export default function Home() {
return (
<Background height="400" width="400">
<h1 className="text-white text-8xl text-left p-36">Fish Bowl</h1>
</Background >
)
}
Is it something wrong with THREE, or is it that next.js can't support vanta?

I have that issue with Halo, so i think the THREE object was not available or was not defined in the HALO.js file.
So i go to the official github repo of Vanta and take the source of Halo and Net (the tutorial effect) file, and i found constructor was missing in the Halo file. So i take the one of Net and put in the Halo file.
constructor(userOptions) {
THREE = userOptions.THREE || THREE;
super(userOptions);
}
Then i import my custom Halo file for the effect and it works.

I was playing around with this and found that, if I keep the Three.js version to 122. I don't get the error. Apparently any version after that has a breaking change.
