How to add Script tag in JSX (Google Analytics edition)



In this article, we are going to be creating a JavaScript file.

Then we are going to try to import that js file as a script tag (in our React component).

Does script tag exist in JSX?

Yes, by default you can add the closing tag <script/>, and then you can import the src javascript file.

The only downside is that you won't be able to add code between the script tags, as you would do with an HTML file. But you can call a script which will call that function.

How to add a Script tag in JSX?

  1. First solution:

If you want to only and exclusively import a script tag.

Then you can do the following:

import scriptTag from './scriptTag'
export default function App() {
return (
<script src={scriptTag} />
// scriptTag.js
function scriptTag() {
console.log('Script Tag has been imported correctly.')

Think on this for a second, and then realize that with that method is all you need. No react helment, and no dependencies. Whether you are trying to add a live chat or Google Analytics into your React app, you can add all the necessary script code in the scriptTag function.


Another way to easily add a script tag in JSX, that doesn't require you to import a package but is setting your application to a potential vulnerability is by using dangerouslySetInnerHTML.

In this case we are going to be adding Google Analytics with this method:

<script async src={`****`} />
__html: `
window.dataLayer = window.dataLayer || [];
function gtag(){dataLayer.push(arguments);}
gtag('js', new Date());
gtag('config', 'G-****', {
page_path: window.location.pathname,
