Can I observe additions to an array with rx.js?

Question

fromArray Rx wiki on github

coffee> rext = require \'rx\'                                                 
coffee> arr = [1..5]                                 


        

Answer 1

Observable.fromArray creates an Observable that immediately fires events for each array items, when you add a Subscriber. So, it won't be "watching" the changes to that array.

If you need a "pushable collection", the Bus class in Bacon.js might be what you're looking for. For RxJs there's my little MessageQueue class that has a similar functionality.
