yarn global

Install packages globally on your operating system.

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

yarn global is a prefix used for a number of commands like add, bin, list and remove. They behave identically to their normal versions except that they use a global directory to store packages. The global command makes executables 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

Defining install location

yarn global bin will output the location where Yarn will install symlinks to your installed executables. You can configure the base location with yarn config set prefix <filepath>. For example, yarn config set prefix ~/.yarn will ensure all global packages will have their executables installed to ~/.yarn/bin.

yarn global dir will print the output of the global installation folder that houses the global node_modules. By default that will be: ~/.config/yarn/global.
