yarn

The yarn commandlet allows to install, configure, and launch npm. Calling devon yarn «args» is more or less the same as calling yarn «args» but with the benefit that the version of npm preferred by your project is used (and will be installed if not yet available).

The arguments (devon yarn «args») are explained by the following table:
