yarn create

Creates new projects from any create-* starter kits.

yarn create <starter-kit-package> [<args>]

This command is a shorthand that helps you do two things at once:

  • Install create-<starter-kit-package> globally, or update the package to the latest version if it already exists
  • Run the create-<starter-kit-package> executable located in the bin field of the starter kit’s package.json, forwarding any <args> to it

For example, yarn create react-app my-app is equivalent to:

$ yarn global add create-react-app
$ create-react-app my-app
