Hi got this error when im trying to install react-qr-reader in version 18 of React

npm ERR! code ERESOLVE npm ERR! ERESOLVE unable to resolve dependency tree npm ERR! npm ERR! While resolving: [email protected] npm ERR!

it works when i install it with --legacy-peer-deps npm add react-qr-reader --legacy-peer-deps

is it ok if i ignore the required version of react for this package? will there be conflicts in the future?

i found the problem regarding in this lib with React 18

there is an error message from react that

this react dom render inside index.js is now deprecated in React 18

instead, use createRoot

when i tried to change this to createRoot, this lib starts to malfunction. it gets infinite loop after qr code capture the looping happen in onResult

so i switch back to render (ReactDOM.render)

Try npm overrides in your package.json:

  "react-qr-reader": {
    "react": "$react",
    "react-dom": "$react-dom"
  }
}

See https://docs.npmjs.com/cli/v8/configuring-npm/package-json#overrides
