The Data Inheritance Plugin allows patterns to inherit data from patterns within its lineage. This means that data from included patterns is merged with the current pattern. The current pattern's data takes precedence.
To add the Data Inheritance Plugin to your project using npm:
npm install git+https://github.com/Altinn/plugin-node-data-inheritance.git
Or add it directly to your project's package.json file and run npm install.
Note: This plugin needs an event which is not (yet?) available in Patternlab node, if it is to be used / tested the following needs to be added to ln. 360 in patternlab.js (Patternlab core lib):
patternlab.events.emit('patternlab-pattern-before-data-merge', patternlab, pattern);
