yarn global

Install packages globally on your operating system.

yarn global <add/bin/ls/remove/upgrade> [--prefix]

yarn global is a prefix used for a number of commands like add, bin, ls and remove. They behave identically to their normal versions except that they use a global directory to store packages. The global command makes binaries available to use on your operating system.

Note: Unlike the --global flag in npm, global is a command which must immediately follow yarn. Entering yarn add global package-name will add the packages named global and package-name locally instead of adding package-name globally.

This is useful for developer tooling that is not part of any individual project but instead is used for local commands. One such example is create-react-app which can be installed globally like this:

$ yarn global add create-react-app --prefix /usr/local
# the `create-react-app` command is now available globally:
$ which create-react-app
$ /usr/local/bin/create-react-app
$ create-react-app
