knockout-observablemap

knockout-es6-collections

Observable maps, sets, weak maps and weak sets.

The collections created are:

• ko.Map
• ko.Set
• ko.WeakSet
• ko.WeakMap

Each of the functions of the keyed collections either observes or mutates the collection.

	Mutates	Observes
Map	set, clear, delete	get, has, values, keys, entries, forEach, valueOf
Set	add, clear, delete	entries, values, keys, has, forEach, valueOf
WeakMap	add, delete, has	valueOf
WeakSet	delete, set	has, get, valueOf

The observable is always triggered asynchronously, so multiple updates will be pooled together into one change.

These functions also expose some Knockout observable functions, namely:

• subscribe(callback[, thisArg]) where the callback receives the entire collection when called
• valueHasMutated()
• getSubscriptionCount()

Changelog

• Fix getSubscription[s]Count
• Add .peek to the observers e.g. map.values.peek() or map.has.peek('x')
• NOTE: This version uses () => ... and spreads, so may need transpiling.

28 Feb 2017 - 🦐 3.0.0

• Fix Set iterator returning entities instead of values
