Sleeping cat You’re getting create-react-app command not found error because you don’t have create-react-app package installed on your machine. You can install it by executing npm install -g create-react-app. If you don’t want to install it locally, you can use npx create-react-app client command. The npx command will not install the package locally but just use that package to do its work. So either way will do the job. There is no issue with using either way.
