There are two different issues here.
The first issue is that calling root.render
without root
as the this
context is not supported.
So this won't work:
const render = createRoot(domNode).render
render(<App />)
You should always write it like this:
const root = createRoot(domNode)
root.render(<App />)
The second issue is that createRoot
and hydrateRoot
have different signatures but you're trying to use them in the same way. That's also incorrect. The second hydrateRoot
argument is required but you are missing it and trying to render()
later, which is not how it's supposed to be used. Please see the hydrateRoot
documentation and examples.
Here is the fixed version of your code:
https://codesandbox.io/s/musing-ully-kyuics?file=/src/index.js
const container = document.getElementById("root");
const reactNode = (
<StrictMode>
<App />
</StrictMode>
);
let root;
if (process.env.SSR) {
root = hydrateRoot(container, reactNode);
} else {
root = createRoot(container);
root.render(reactNode);
}
Note that hydrateRoot
is done in a single step because we're specifying which tree to hydrate it with. It doesn't need an additional render. However, createRoot
needs a full render because it's initially empty.
Hope this helps.

The error you're seeing suggests that container is undefined, which is causing the error when attempting to access _internalRoot. This could happen if the element with the ID of "root" doesn't exist in the HTML document.
you could try something like this, this would solve your issue
document.addEventListener('DOMContentLoaded', () => {
renderDom();
});
