ShellJS
Portable Unix shell commands for Node.js
...ShellJS is proudly tested on every node release since v8! ShellJS now supports third-party plugins! You can learn more about using plugins and writing your own ShellJS commands in the wiki. The most important thing is to require the most recent version of ShellJS as a peer-dependency. If you want to add unit tests for your plugin as well, you'll probably want it as a dev-dependency too.
