yarn exec

execute a shell script

Terminal window
yarn exec <commandName> ...

Execute a single shell command :

Terminal window
yarn exec echo Hello World

Execute a shell script :

Terminal window
yarn exec "tsc & babel src --out-dir lib"

This command simply executes a shell script within the context of the root directory of the active workspace using the portable shell.

It also makes sure to call it in a way that’s compatible with the current project (for example, on PnP projects the environment will be setup in such a way that PnP will be correctly injected into the environment).
