Promise Cancellation Is Dead — Long Live Promise Cancellation!
Promise Cancellation Is Dead — Long Live Promise Cancellation! Not very long ago Domenic Denicola (worth a follow, a very smart guy) withdrew his proposal for promise cancellation from the TC39. A lot of people might think that means that promise cancellation isn’t coming to JavaScript. Those people would be right, if you couldn’t already cancel a promise via very similar means to what was propose
Replace Subscriptions with Cancellation Tokens · Issue #112 · tc39/proposal-observable
In this model, Cancellation tokens replace Subscriptions. Instead of an Observable creating a Subscription object when subscribe is called, the consumer creates a CT and passes it to the subscribe method alongside an Observer. Internally each Observable creates its own CT, registers all of its cleanup behavior to run on its CT’s cancellation, then links the internal CT with the one passed to the s
Observables and Finnish Notation
Once in a while I’m asked what I think about naming observables with an $ suffix. For example: const click$ = Observable.fromEvent(button, 'click');Well, I personally could take it or leave it, but I know some of you can’t live without it. What I want to write an article about, however, is the origin of “Finnish Notation” and different dialects. Hungarian NotationWith Hungarian Notation, one adds
redux-observable
Created by Jay Phelps and myself for use on our projects at Netflix, redux-observable is middleware for redux that is inspired by redux-thunk. redux-observable allows developers to dispatch a function that returns an observable, promise or iterable of action(s). When the observable emits an action, or the promise resolves an action, or the iterable gives an action out, that action is then dispatch
André Staltz - Why we built xstream
For the past two years I have been using RxJS extensively, in Cycle.js and in other contexts. Recently, TylorS and I have decided to build a new reactive streams library comparable to RxJS, called xstream. TL;DR: we needed a reactive stream library tailored for Cycle.js. It needs to be “hot” only, so users don’t need to think about subscription semantics hidden in drivers. It should have only a fe
Plug and Play All Your Observable Streams With Cycle.js
The real tragedy would be if people forgot, you can have new ideas about programming models… If the next generation of programmers grows up never being exposed to these ideas, and they teach [only what they…
