Reactive Extensions for Javascript – Observable vs ConnectableObservable

For those of you who are famil­iar with Reac­tive Exten­sions you should know all about observ­ables already, but did you know that there’s anoth­er kind of observ­able sequence – Rx.ConnectableObservable. The dif­fer­ence between the two types of observ­able sequences is well explained here, in short, a con­nectable observ­able sequence allows you to share the same …

Reactive Extensions for Javascript – Causing side effects with Do

I wrote pre­vi­ous­ly about how you can set up mul­ti­ple observ­able sequences and sub­scribe to them with mul­ti­ple observers and cre­ate a many-to-many rela­tion­ship between them. Whilst this is a very flex­i­ble mod­el with a clear sep­a­ra­tion of respon­si­bil­i­ties, often it requires more work to set up and is more than what you need for …

Rx framework — IObservable<T>.Retry

As Wes Dyer put very ele­gant­ly: Retry is to Repeat as Catch is to Con­cat Ok ok, I know that’s not an exact quote, but I’m sure this is what he intend­ed to say in the first instance :-P Any­how, the IObservable<T>.Retry method has all the same fea­tures of its Repeat sis­ter method, in that: …
