Conditional Retry logic in Rx.JS in 5 minutes!

Hello Every-buddy! I am Oleksandr, front-end developer in http://tonicforhealth.com/

In this lightning talk I want to share my experience in using Rx.JS retry operator when you need to customize its behaviour for specific Observable error. it is a shortened version of my speech on JS-FW-days conference in Ukraine.

Content

We know that Rx.JS has retry operator. It means - do one more run for source Observable again if previous run returned error. But what if I need to retry for specific errorCode only? Say for http 401 Unauthorized? CatchError, map and two smoking barrels retry operators in my 5 min introduction to conditional retry in Rx.JS.

BONUS: Interesting use-case for Observable-wrapped http requests!
