1 year ago To inject React components into a site using a content script, you will need to call React's createRoot on a particular DOM node, which gives React the ability to manipulate the contents of the DOM node.
Let's say we have a document which looks like the following:
<html>
<body>
<div id="container">
<div id="content">Some content</div>
</div>
</body>
</html>And you want to inject your React component App into the div with id container
Your content script could look something like this:
import React from 'react';
import { createRoot } from 'react-dom/client';
import App from './App.jsx';
const containerEl = document.getElementById("container");
const reactRootEl = document.createElement("div");
reactRootEl.setAttribute("id", "reactRoot");
containerEl.appendChild(reactRootEl);
const reactRoot = createRoot(reactRootEl);
reactRoot.render(<App/>);Hope this helps!
Hi there, I am currently trying to do some DOM manipulation / display custom components within www.example.com.
I know that in order to modify the DOM elements within a certain domain the work would need to be done within the src/pages/Content directory, but I'm struggling to figure out how would I go about injecting custom React components into there. Is this even a possible thing to do or do I have the wrong idea about Chrome's content scripts?
Thank you!
