[With next 11 requiring react 17](https://nextjs.org/blog/next-11#upgrade-guide), most of the examples need to be updated, so the following snippet updated all the examples to a compatible react version. ```bash cd examples/ fd -g 'package.json' | xargs sed -r -i 's/"react": ".*"/"react": "^17.0.2"/ fd -g 'package.json' | xargs sed -r -i 's/"react-dom": ".*"/"react-dom": "^17.0.2"/' # exclude experimental react version git checkout with-reason-relay/package.json ``` |
