Add the embed code to your React app

Open the React component, you’d like to add your Senja widget to.

Paste the Senja embed code:


Alternatively, add the <script> portion of the Senja embed code just before the end of your <head> or <body> tag of your React website.


And embed the <div> portion in any React component.

Add the embed code to your NextJS app

Open the +page.tsx file, or page.jsx file you’d like to add your Senja widget to.

Paste the Senja embed code:

// import this:
import Script from "next/script";

export default function SenjaPage() {
  return (
			{/* This changed from <script> to <Script> */}
If you’re using NextJS, Don’t use the default <script> tag! To prevent hydration errors, replace the script tag with the next/script component.

Once you do this, your Senja widget will be rendered on the page, like this:
