QUESTION

Deprecation notice: ReactDOM.render is no longer supported in React 18

Asked 2022-Apr-05 at 08:50

I get this error every time I create a new React App and I don't know how to fix it:

Warning: ReactDOM.render is no longer supported in React 18. Use createRoot instead. Until you switch to the new API, your app will behave as if it's running React 17. Learn more: https://reactjs.org/link/switch-to-createroot

I created my react app using: npx create-react-app my-app

ANSWER

Answered 2022-Apr-05 at 08:44

In your file index.js, change to:

import React from "react";
import ReactDOM from "react-dom/client";
import "./index.css";
import App from "./App";
import reportWebVitals from "./reportWebVitals";

const root = ReactDOM.createRoot(document.getElementById("root"));
root.render(
  <React.StrictMode>
    <App />
  </React.StrictMode>
);

reportWebVitals();
