Hey there! Good news. Life is boring due to corona so I spend the whole weekend moving the code from the articles here to their own package:
So here it is!
This package is structured as a mono repo to give enough infrastructure to each field I will create. It uses a combination of yarn and lerna workspaces. Currently it contains two packages that you can install like so:
npm install --save tinacms-condition-field
npm install --save tinacms-relation-field
Feel free to test it and report any issues.
