Upgrade to React 18

Updating packages

To use React 18's newest features, you need at least version 3.0.0 of Remotion.

- "remotion": "2.6.15"
- "@remotion/bundler": "2.6.15"
- "@remotion/cli": "2.6.15"
- "@remotion/renderer": "2.6.15"
+ "remotion": "3.0.0"
+ "@remotion/bundler": "3.0.0"
+ "@remotion/cli": "3.0.0"
+ "@remotion/renderer": "3.0.0"

You need to upgrade both react and react-dom:

- "react": "17.0.1"
- "react-dom": "17.0.1"
+ "react": "18.2.0"
+ "react-dom": "18.2.0"

If you use TypeScript, update to the newest types as well:

- "@types/react": "17.0.3"
+ "@types/react": "18.0.0"

Run npm i, or yarn, or pnpm i afterwards, matching your package manager.

Fixing React.FC types

The types for React.FC have changed to no longer include children. If you get a type error, change

const MyComp: React.FC = ({ children }) => <div>{children}</div>;

to:

const MyComp: React.FC<{
  children: React.ReactNode;
}> = ({ children }) => <div>{children}</div>;

No action required for createRoot()

If React 18 is installed, Remotion will automatically use createRoot() from react-dom/client instead of render from react-dom. You don't need to do anything.
