freight-trust uses lerna to manage multi-package repositories. Each freight-trust/carbon module is defined in its own npm package in the packages/ directory.
The entry point of these modules is @freight-trust/carbon-*.
Install lerna:
$ npm install -g lerna
$ npm install -g yarnThe setup is done, you can now write your command and organize your module as you want in: packages/. You can have a look at packages/ which is a good starting example to follow.
