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.
Apologies if this is very basic as I am a complete react beginner, I'm asking this question here as I have no idea where to start to get this working.
Im trying to convert this raw html code into a react app.
<body>
<div style="width: 600px; height: 400px;" id="aww-wrapper">
</div>
<script src="https://awwapp.com/static/widget/js/aww3.min.js">
</script>
<script type="text/javascript">
var aww = new AwwBoard('#aww-wrapper', {
});
</script>
</body>
This code creates a small whiteboard app on the webpage.
I have tried to implement it into the app component in react but am having trouble getting the 'var aww = ...' script to work.
import React from 'react';
import './App.css';
import ScriptTag from 'react-script-tag'
function App() {
return (
<div className="App">
<div style={{width:'600px', height:'400px'}} id="aww-wrapper">
</div>
<ScriptTag src="https://awwapp.com/static/widget/js/aww3.min.js" />
<ScriptTag type="text/javascript">
var aww = new AwwBoard('#aww-wrapper', {
});
</ScriptTag>
</div>
);
}
export default App;
I am using scripttag to get the external javascript onto the web page, but it isnt working for the 'var aww = ...' part.
It would be a huge help if anyone has a general direction that they can direct me to in order to implement the javascript into the react code.
You will need to create an initialing function wrapper for the AwwBoard. The function will create and configure a script object. The AwwBoard function will return a promise to the caller, which will provide the AwwBoard instance for later use (to access its methods) once the javascript has executed.
We also want to pass config params as well as a mount Ref for the component.
To achieve this, I created the following function which takes a ref (for the div you want to mount the AwwBoard) as well as configuration params. It loads the script, and resolves the promise with the instance.
const AwwBoard = (mountRef: React.Ref, params: Object = {}) => {
let promise = new Promise(function (resolve, reject) {
var script = document.createElement("script");
script.src = "https://awwapp.com/static/widget/js/aww3.min.js";
script.onload = function () {
//AwwBoard should be available on the window object after loading the script
const { AwwBoard } = window;
//create a new instance
var aww = new AwwBoard(`#${mountRef.id}`, params);
//resolve the promise and return the instance.
resolve(aww);
};
document.getElementsByTagName("head")[0].appendChild(script);
});
return promise;
};
export default AwwBoard;
Now we set up a div with a react ref, and a useEffect which loads the AwwBoard on "componentDidMount"
import React, { useEffect } from "react";
import "./styles.css";
import AwwBoard from "./AwwBoard";
export default function App() {
const awwBoardInstance = React.useRef(); //access methods on the board here
const awwBoardMountRef = React.useRef(null); //mounting ref for the AwwBoard
useEffect(() => {
AwwBoard(awwBoardMountRef.current, {}).then((instance) => {
awwBoardInstance.current = instance;
});
},[]);
return (
<div className="App">
<div
style={{ width: "600px", height: "400px" }}
id="aww-wrapper"
ref={awwBoardMountRef}
></div>
</div>
);
}
CodeSandbox
It would be better if you bundled the aww3.min.js into your app and then did something like this:
import React from 'react';
import { useEffect } from "react";
import './App.css';
import './aww3.min.js'
function App() {
useEffect(() => {
new AwwBoard('#aww-wrapper', {
});
}, [])
return (
<div className="App">
<div style={{width:'600px', height:'400px'}} id="aww-wrapper">
</div>
</div>
);
}
export default App;
I'm making a React application and I need to run a Javascript script only in one component, making reference to one of the div's.
I know there are some libraries to do so, but I wonder if there's a more direct way to do it. Right now I do this:
import React, { Component } from "react";
import "../ThisComponent.css";
export default class MyComponent extends Component {
render() {
return (
<div>
<div id="scriptTarget" />
<div className="main">
// Other stuff
</div>
<script src="js/myScript.js" />
</div>
);
}
}
But nothing happens. The script is stored in public/js/myScript.js.
Thanks!
I finally solved it by adding the componentDidMount function before rendering the component. Like this:
import React, { Component } from "react";
import "../ThisComponent.css";
export default class MyComponent extends Component {
componentDidMount() {
const script = document.createElement("script");
script.src = "js/myScript.js";
script.async = true;
document.body.appendChild(script);
}
render() {
return (
<div>
<div id="scriptTarget" />
<div className="main">
// Other stuff
</div>
</div>
);
}
}
If somebody has a better solution please feel free to share it. I'll be aware to further recomendations.
By using dangerouslySetInnerHTML you can add any valid html you want to your elements.
import React, { Component } from "react";
import "../ThisComponent.css";
export default class MyComponent extends Component {
render() {
return (
<div dangerouslySetInnerHTML="<script src='js/myScript.js' />" >
<div id="scriptTarget" />
<div className="main">
// Other stuff
</div>
</div>
);
}
}
I should mention though that as the attribute name suggest, its use is strongly discouraged.
export default class MyComponent extends Component {
componentDidMount() {
const script = document.createElement("script");
script.innerHTML = "window.onload = function() {\n" +
...
"}"
script.async = true;
document.body.appendChild(script);
}
render() {
return (
<div>
</div>
);
}
}
You can also use a external component "Helmet" for implement script tags and you can also use link tag,meta tag,style tag etc with the help of this component.
I have a relatively straightforward issue of trying to add inline scripting to a React component. What I have so far:
'use strict';
import '../../styles/pages/people.scss';
import React, { Component } from 'react';
import DocumentTitle from 'react-document-title';
import { prefix } from '../../core/util';
export default class extends Component {
render() {
return (
<DocumentTitle title="People">
<article className={[prefix('people'), prefix('people', 'index')].join(' ')}>
<h1 className="tk-brandon-grotesque">People</h1>
<script src="https://use.typekit.net/foobar.js"></script>
<script dangerouslySetInnerHTML={{__html: 'try{Typekit.load({ async: true });}catch(e){}'}}></script>
</article>
</DocumentTitle>
);
}
};
I have also tried:
<script src="https://use.typekit.net/foobar.js"></script>
<script>try{Typekit.load({ async: true });}catch(e){}</script>
Neither approach seems to execute the desired script. I'm guessing it's a simple thing I'm missing. Can anybody help out?
PS: Ignore the foobar, I have a real id actually in use that I didn't feel like sharing.
Edit: Things change fast and this is outdated - see update
Do you want to fetch and execute the script again and again, every time this component is rendered, or just once when this component is mounted into the DOM?
Perhaps try something like this:
componentDidMount () {
const script = document.createElement("script");
script.src = "https://use.typekit.net/foobar.js";
script.async = true;
document.body.appendChild(script);
}
However, this is only really helpful if the script you want to load isn't available as a module/package. First, I would always:
Look for the package on npm
Download and install the package in my project (npm install typekit)
import the package where I need it (import Typekit from 'typekit';)
This is likely how you installed the packages react and react-document-title from your example, and there is a Typekit package available on npm.
Update:
Now that we have hooks, a better approach might be to use useEffect like so:
useEffect(() => {
const script = document.createElement('script');
script.src = "https://use.typekit.net/foobar.js";
script.async = true;
document.body.appendChild(script);
return () => {
document.body.removeChild(script);
}
}, []);
Which makes it a great candidate for a custom hook (eg: hooks/useScript.js):
import { useEffect } from 'react';
const useScript = url => {
useEffect(() => {
const script = document.createElement('script');
script.src = url;
script.async = true;
document.body.appendChild(script);
return () => {
document.body.removeChild(script);
}
}, [url]);
};
export default useScript;
Which can be used like so:
import useScript from 'hooks/useScript';
const MyComponent = props => {
useScript('https://use.typekit.net/foobar.js');
// rest of your component
}
My favorite way is to use React Helmet – it's a component that allows for easy manipulation of the document head in a way you're probably already used to.
e.g.
import React from "react";
import {Helmet} from "react-helmet";
class Application extends React.Component {
render () {
return (
<div className="application">
<Helmet>
<script src="https://use.typekit.net/foobar.js"></script>
<script>try{Typekit.load({ async: true });}catch(e){}</script>
</Helmet>
...
</div>
);
}
};
https://github.com/nfl/react-helmet
Further to the answers above you can do this:
import React from 'react';
export default class Test extends React.Component {
constructor(props) {
super(props);
}
componentDidMount() {
const s = document.createElement('script');
s.type = 'text/javascript';
s.async = true;
s.innerHTML = "document.write('This is output by document.write()!')";
this.instance.appendChild(s);
}
render() {
return <div ref={el => (this.instance = el)} />;
}
}
The div is bound to this and the script is injected into it.
Demo can be found on codesandbox.io
This answer explains the why behind this behavior.
Any approach to render the script tag doesn't work as expected:
Using the script tag for external scripts
Using dangerouslySetInnerHTML
Why
React DOM (the renderer for react on web) uses createElement calls to render JSX into DOM elements.
createElement uses the innerHTML DOM API to finally add these to the DOM (see code in React source). innerHTML does not execute script tag added as a security consideration. And this is the reason why in turn rendering script tags in React doesn't work as expected.
For how to use script tags in React check some other answers on this page.
If you need to have <script> block in SSR (server-side rendering), an approach with componentDidMount will not work.
You can use react-safe library instead.
The code in React will be:
import Safe from "react-safe"
// in render
<Safe.script src="https://use.typekit.net/foobar.js"></Safe.script>
<Safe.script>{
`try{Typekit.load({ async: true });}catch(e){}`
}
</Safe.script>
The answer Alex Mcmillan provided helped me the most but didn't quite work for a more complex script tag.
I slightly tweaked his answer to come up with a solution for a long tag with various functions that was additionally already setting "src".
(For my use case the script needed to live in head which is reflected here as well):
componentWillMount () {
const script = document.createElement("script");
const scriptText = document.createTextNode("complex script with functions i.e. everything that would go inside the script tags");
script.appendChild(scriptText);
document.head.appendChild(script);
}
I tried to edit the accepted answer by #Alex McMillan but it won't let me so heres a separate answer where your able to get the value of the library your loading in. A very important distinction that people asked for and I needed for my implementation with stripe.js.
useScript.js
import { useState, useEffect } from 'react'
export const useScript = (url, name) => {
const [lib, setLib] = useState({})
useEffect(() => {
const script = document.createElement('script')
script.src = url
script.async = true
script.onload = () => setLib({ [name]: window[name] })
document.body.appendChild(script)
return () => {
document.body.removeChild(script)
}
}, [url])
return lib
}
usage looks like
const PaymentCard = (props) => {
const { Stripe } = useScript('https://js.stripe.com/v2/', 'Stripe')
}
NOTE: Saving the library inside an object because often times the library is a function and React will execute the function when storing in state to check for changes -- which will break libs (like Stripe) that expect to be called with specific args -- so we store that in an object to hide that from React and protect library functions from being called.
You can also use react helmet
import React from "react";
import {Helmet} from "react-helmet";
class Application extends React.Component {
render () {
return (
<div className="application">
<Helmet>
<meta charSet="utf-8" />
<title>My Title</title>
<link rel="canonical" href="http://example.com/example" />
<script src="/path/to/resource.js" type="text/javascript" />
</Helmet>
...
</div>
);
}
};
Helmet takes plain HTML tags and outputs plain HTML tags. It's dead simple, and React beginner friendly.
I created a React component for this specific case: https://github.com/coreyleelarson/react-typekit
Just need to pass in your Typekit Kit ID as a prop and you're good to go.
import React from 'react';
import Typekit from 'react-typekit';
const HtmlLayout = () => (
<html>
<body>
<h1>My Example React Component</h1>
<Typekit kitId="abc123" />
</body>
</html>
);
export default HtmlLayout;
There is a very nice workaround using Range.createContextualFragment.
/**
* Like React's dangerouslySetInnerHTML, but also with JS evaluation.
* Usage:
* <div ref={setDangerousHtml.bind(null, html)}/>
*/
function setDangerousHtml(html, el) {
if(el === null) return;
const range = document.createRange();
range.selectNodeContents(el);
range.deleteContents();
el.appendChild(range.createContextualFragment(html));
}
This works for arbitrary HTML and also retains context information such as document.currentScript.
Here is how I was finally able to add two external JavaScript files in my React JS code:
These are the steps I followed.
Step 1:
I installed React-Helmet using npm i react-helmet from the terminal while inside my react-app folder path.
Step 2:
I then added import {Helmet} from "react-helmet"; header in my code.
Step 3:
Finally, in my code this is
how I added the external JS files using Helment
<Helmet>
<script src = "path/to/my/js/file1.js" type = "text/javascript" />
<script src = "path/to/my/js/file2.js" type = "text/javascript" />
</Helmet>
You can use npm postscribe to load script in react component
postscribe('#mydiv', '<script src="https://use.typekit.net/foobar.js"></script>')
You can find best answer at the following link:
https://cleverbeagle.com/blog/articles/tutorial-how-to-load-third-party-scripts-dynamically-in-javascript
const loadDynamicScript = (callback) => {
const existingScript = document.getElementById('scriptId');
if (!existingScript) {
const script = document.createElement('script');
script.src = 'url'; // URL for the third-party library being loaded.
script.id = 'libraryName'; // e.g., googleMaps or stripe
document.body.appendChild(script);
script.onload = () => {
if (callback) callback();
};
}
if (existingScript && callback) callback();
};
To add script tag or code in head tag <head>, use react-helmet package. it is light and have good documentation.
To add Js code in script tag inside body,
function htmlDecode(html) {
return html.replace(/&([a-z]+);/ig, (match, entity) => {
const entities = { amp: '&', apos: '\'', gt: '>', lt: '<', nbsp: '\xa0', quot: '"' };
entity = entity.toLowerCase();
if (entities.hasOwnProperty(entity)) {
return entities[entity];
}
return match;
});
}
render() {
const scriptCode = `<script type="text/javascript">
{(function() {
window.hello={
FIRST_NAME: 'firstName',
LAST_NAME: 'lastName',
};
})()}
</script>`
return(
<div dangerouslySetInnerHTML={{ __html: this.htmlDecode(scriptCode) }} />;
);
}
this code can be tested by console.log(windows.hello)
Very similar to other answers just using default values to clean up undefined checks
import { useEffect } from 'react'
const useScript = (url, selector = 'body', async = true) => {
useEffect(() => {
const element = document.querySelector(selector)
const script = document.createElement('script')
script.src = url
script.async = async
element.appendChild(script)
return () => {
element.removeChild(script)
}
}, [url])
}
export default useScript
usage
useScript('/path/to/local/script.js') // async on body
useScript('https://path/to/remote/script.js', 'html') // async on html
useScript('/path/to/local/script.js', 'html', false) // not async on html.. e.g. this will block
According to Alex McMillan's solution, I have the following adaptation.
My own environment: React 16.8+, next v9+
// add a custom component named Script
// hooks/Script.js
import { useEffect } from 'react'
// react-helmet don't guarantee the scripts execution order
export default function Script(props) {
// Ruels: alwasy use effect at the top level and from React Functions
useEffect(() => {
const script = document.createElement('script')
// src, async, onload
Object.assign(script, props)
let { parent='body' } = props
let parentNode = document.querySelector(parent)
parentNode.appendChild(script)
return () => {
parentNode.removeChild(script)
}
} )
return null // Return null is necessary for the moment.
}
// Use the custom compoennt, just import it and substitute the old lower case <script> tag with the custom camel case <Script> tag would suffice.
// index.js
import Script from "../hooks/Script";
<Fragment>
{/* Google Map */}
<div ref={el => this.el = el} className="gmap"></div>
{/* Old html script */}
{/*<script type="text/javascript" src="http://maps.google.com/maps/api/js"></script>*/}
{/* new custom Script component */}
<Script async={false} type="text/javascript" src='http://maps.google.com/maps/api/js' />
</Fragment>
A bit late to the party but I decided to create my own one after looking at #Alex Macmillan answers and that was by passing two extra parameters; the position in which to place the scripts such as or and setting up the async to true/false, here it is:
import { useEffect } from 'react';
const useScript = (url, position, async) => {
useEffect(() => {
const placement = document.querySelector(position);
const script = document.createElement('script');
script.src = url;
script.async = typeof async === 'undefined' ? true : async;
placement.appendChild(script);
return () => {
placement.removeChild(script);
};
}, [url]);
};
export default useScript;
The way to call it is exactly the same as shown in the accepted answer of this post but with two extra(again) parameters:
// First string is your URL
// Second string can be head or body
// Third parameter is true or false.
useScript("string", "string", bool);
I recently faced the issue,
Tried multiple solutions given here, at last sattled with iframe,
Iframe seems to work seamlessly if it you are trying to integrate a js plugin on a specific screen
<iframe

`}
/>
componentDidMount() {
const head = document.querySelector("head");
const script = document.createElement("script");
script.setAttribute(

head.appendChild(script);
}
just add in body in html file
<script src="https://unpkg.com/react-dom#17/umd/react-dom.development.js" crossorigin></script>
Honestly, for React - don't bother with messing around adding <script> tags to your header. It's a pain in the ass to get a callback when they have loaded fully. Instead, use a package like #charlietango/useScript to load the script when you need it and get a status update when it is completed.
Example usage:
import React from 'react'
import useScript, { ScriptStatus } from '#charlietango/use-script'
const Component = () => {
const [ready, status] = useScript('https://api.google.com/api.js')
if (status === ScriptStatus.ERROR) {
return <div>Failed to load Google API</div>
}
return <div>Google API Ready: {ready}</div>
}
export default Component
PS. If you're using redux to tell other components when your script has loaded, and are using redux-persist like I was, don't forget to include a modifier on your redux-persist setup that always sets the script loaded redux value to false in the redux backup.
for multiple scripts, use this
var loadScript = function(src) {
var tag = document.createElement('script');
tag.async = false;
tag.src = src;
document.getElementsByTagName('body').appendChild(tag);
}
loadScript('//cdnjs.com/some/library.js')
loadScript('//cdnjs.com/some/other/library.js')
For a more complete useScript implementation that supports loading status and error handling, check out this from useHooks.
Usage
function App() {
const status = useScript(
"https://pm28k14qlj.codesandbox.io/test-external-script.js"
);
return (
<div>
<div>
Script status: <b>{status}</b>
</div>
{status === "ready" && (
<div>
Script function call response: <b>{TEST_SCRIPT.start()}</b>
</div>
)}
</div>
);
}
Hook
function useScript(src) {
// Keep track of script status ("idle", "loading", "ready", "error")
const [status, setStatus] = useState(src ? "loading" : "idle");
useEffect(
() => {
// Allow falsy src value if waiting on other data needed for
// constructing the script URL passed to this hook.
if (!src) {
setStatus("idle");
return;
}
// Fetch existing script element by src
// It may have been added by another intance of this hook
let script = document.querySelector(`script[src="${src}"]`);
if (!script) {
// Create script
script = document.createElement("script");
script.src = src;
script.async = true;
script.setAttribute("data-status", "loading");
// Add script to document body
document.body.appendChild(script);
// Store status in attribute on script
// This can be read by other instances of this hook
const setAttributeFromEvent = (event) => {
script.setAttribute(
"data-status",
event.type === "load" ? "ready" : "error"
);
};
script.addEventListener("load", setAttributeFromEvent);
script.addEventListener("error", setAttributeFromEvent);
} else {
// Grab existing script status from attribute and set to state.
setStatus(script.getAttribute("data-status"));
}
// Script event handler to update status in state
// Note: Even if the script already exists we still need to add
// event handlers to update the state for *this* hook instance.
const setStateFromEvent = (event) => {
setStatus(event.type === "load" ? "ready" : "error");
};
// Add event listeners
script.addEventListener("load", setStateFromEvent);
script.addEventListener("error", setStateFromEvent);
// Remove event listeners on cleanup
return () => {
if (script) {
script.removeEventListener("load", setStateFromEvent);
script.removeEventListener("error", setStateFromEvent);
}
};
},
[src] // Only re-run effect if script src changes
);
return status;
}
I had raw html string with javascript/Jquery
i installed npm library dangerously-set-html-content
npm i dangerously-set-html-content
import InnerHTML from 'dangerously-set-html-content'
<div>
<InnerHTML html={html}/>
</div>
or
import InnerHTML from 'dangerously-set-html-content'
const renderhtml=`<!DOCTYPE html><html lang="en"><head><meta charset="utf-8"><title> is not defined</title>$(document).ready(function(){ $("button").click(function(){ alert("jQuery is working perfectly."); }); });</script></head><body> <button type="button">Test jQuery Code</button></body></html>`
<div>
<InnerHTML html={renderhtml}/>
</div>
Make sure you add jquery cdn to public/index.html file
<script src="https://code.jquery.com/jquery-3.3.1.min.js" integrity="sha256-FgpCb/KJQlLNfOu91ta32o/NMZxltwRo8QtmkMRdAu8=" crossorigin="anonymous" async="true" ></script>
You could try to use the following:
Make sure you trust the script
<script>{`
function myFunction(index, row) {
return index;
}
`}
</script>
You have to create a component for this script, you call this component as a standard ES6 script tag

Solution depends on scenario. Like in my case, I had to load a calendly embed inside a react component.
Calendly looks for a div and reads from it's data-url attribute and loads an iframe inside the said div.
It is all good when you first load the page: first, div with data-url is rendered. Then calendly script is added to body. Browser downloads and evaluates it and we all go home happy.
Problem comes when you navigate away and then come back into the page. This time the script is still in body and browser doesn't re-download & re-evaluate it.
Fix:
On componentWillUnmount find and remove the script element. Then on re mount, repeat the above steps.
Enter $.getScript. It is a nifty jquery helper that takes a script URI and a success callback. Once the script it loaded, it evaluates it and fires your success callback. All I have to do is in my componentDidMount $.getScript(url). My render method already has the calendly div. And it works smooth.
I saw the same problem, until I found this package, quite easy to implement, I hope it works as it worked for me :)

import React from 'react';
import Script from '#gumgum/react-script-tag';
import './App.css';
function App() {
return (
<div >
<h1> Graphs</h1>
<div class="flourish-embed flourish-network" data-src="visualisation/8262420">
<Script src"your script"
</Script>
</div>
</div>
);
}
export default App;
You can put your script in an Html file before react is being called.
