Typescript is added to the version 16 react application created with create react app. I have installed the latest v.18 version of @types/react and @types/react-dom, but I would like to know if it is a problem that the version is different from react. Thank you.

Yes, as you'll have TS types for React 18, but JS code for React 16. For example, you may be able to import a new feature from React 18 but get a runtime error because you only have React 16.

You can solve this by using @types/react and @types/react-dom version 16 until you're ready to upgrade to React 18.

npx typesync will resolve type syncing issues.

You can go a step further and add this in your package.json:

“postinstall”: “npx typesync”

Now every time you install or update your packages you’ll automatically run the postinstall script!
