SignalK-merge

Utility to merge two Signal K objects, resolving conflicts using the timestamp of child objects. Small javascript utility to merge two Signal K objects or merge an child-object into a vessel in an existing Signal K tree. Conflicts are resolved by comparing timestamps.

Installation

npm install signalk-merge

Usage

var merge 	= require('signalk-merge');

/*
	Merge a full signalK object into another.
	Arguments:
		0: full signalk object
		1: full signalk object
*/
var signalk = merge.full(signal_k_object_a, signal_k_object_b);


/*
	Merge a partial 'navigation' object into vessel 'self'.
	Arguments:
		0: full signalk object
		1: vessel identifier or 'self'
		2: object to merge into the vessel
*/
signalk = merge.into(signalk, 'self', {
	"navigation": {
		"state": {
			"timestamp": "",
			"state": "under way sailing"
		}
	}
});

Note: At the moment, it's not possible to merge partial objects into anything else but a vessel. Scheduled for the next release.
