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()

• 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
