Reactive programming (II.) - Introducing Reactive LINQ In this article I'm going to introduce my project Reactive LINQ. This is largely inspired by the ideas that come from functional reactive programming in the Haskell language and from functionality that's available for working in events in F#. I introduced these ideas in my previous article in this mini-series, so if you're interested in learning more about these interesting technologies, you should definitely read the previous article about First class events in F#. In this article, we're going to look how to apply the same ideas to the C# language and how to use LINQ queries for processing events. This article is just another my article that shows how to implement some idea from functional programming in C#. I believe this will once again show that the new features in the C# 3.0 aren't just about querying databases The idea: Event is a stream
Espresso provides an API as soon as you register your database. It introspects the database schema and populates the repository with the required metadata. Each table becomes a REST endpoint with services such as pagination, filtering, and optimistic locking out-of-the-box.
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…
In this article, we’ll compare two options for handling async logic in Redux: redux-thunk and redux-observable. Redux-saga is another option that shares a lot of similarities with redux-observable, but it’s not included in this article.
Continuing on from my previous article Want to learn JavaScript in 2015 / 2016. I’m going to walk you through what else I’ve been up to in the world of Javascript. Initially I’d planned to talk about…
This article is not going to cover what React is or why you should learn it. Instead, this is a practical introduction to the fundamentals of React.js for those who are already familiar with JavaScript and know the basics of the DOM API.
If you’re new to RxJS, you may have experimented with creating a few observables and applying functions like map, filter, and scan. These are intuitive for most developers, since they constitute the…
Timber program reacts to events sent to it from its execution environment. This process is potentially infinite, and the order of external events is not known in advance.To capture this intuition, Timber defines its primary run-time structure to be a set of interconnected reactive objects, that each encapsulate a piece of the global program state. A reactive object is a passive entity defined by a set of methods. Between invocations, a Timber object just maintains its state, ready to react . Timber objects evolve in parallel, although the methods belonging to a particular object are always run under mutually exclusion. Concurrency as well as state protection is thus implicit. Methods are either asynchronous or synchronous, as denoted by the keywords action and request, respectively. The most radical property of Timber is that it is free from any indefinitely blocking constructs; because of this, a Timber object is always fully responsive when not actively executing code.

Jay Phelps (@_jayphelps ) talks about why Netflix loves reactive programming with Rx. In this talk he shares the basics of RxJS 5 Observables and how they ca...
Reactive programming with Observables can seem like a hard skill to learn. In this talk you will see Andre live code and explain the basics of RxJS Observabl...
In this article, we have a look at four independent dimensions of reactive programming as well as the vocabulary that comes with them. Read on to find out more.
Use this operator when the order is important, for example when you need to send HTTP requests that should be in order. In our example, every time I’m clicking on the document, the previous interval…
In 2014, front-end developer André Staltz set out to solve an imminent problem that developers are facing, especially in the Web world: dealing with large code bases and data flow. While even large…
Every now and then I’m asked a question about how to use async functions or promises with RxJS, or worse, I’m told some “fact” about how async-await and Observables don’t really “work together”. RxJS…
React's future is going to be more functional, and less OOP. What if that future is already reality? How would it look like? React's foundations are reactive...
These are 3 situations that we can come across while building Angular apps using RxJs. We are going to go over why the issue happens and how to fix it.
This post is about an experimental approach and I am sure there are other approaches for solving a similar problem. If so, please comment on this article. Demo…
The ngrx team decided that we don’t need middleware anymore, in most cases, we can use meta-reducers to achieve the same effects. higher order function is a function that may receive a function as…
A full stack, reactive architecture for general purpose programming. Algebraic and monadically composable primitives for concurrency, parallelism, event handling, transactions, multithreading, Web, and distributed computing with complete de-inversion of control (No callbacks, no blocking, pure state)
RxJS is a library for reactive programming using Observables, to make it easier to compose asynchronous or callback-based code. This project is a rewrite of Reactive-Extensions/RxJS with better performance, better modularity, better debuggable call stacks, while staying mostly backwards compatible, with some breaking changes that reduce the API surface
A tutorial on how to use RxJS in React for state management. It shows how to implement a Rx.js higher-order component (hoc) that takes over the observable streams ...
I’m an avid user of Redux-Observable, and while it masks a lot of the difficulties in using RxJS, you still need a deeper understanding of RxJS to handle really complex use cases. Using WebSockets…
Reactive paradigm is a declarative way to manage changes in application status (versus traditional imperative programming), based on the concept of event streams.
Those operators are pure functions that can be used as standalone operators instead of methods on an observable. Let’s say I know that I’m going to re-use this filter, well, with lettable operators I…
Reflex FRP is a composable, cross-platform functional reactive programming framework for Haskell. It allows you to build interactive components in pure functional style, working in harmony with established Haskell techniques and improving the quality and elegance of your applications.
Redux-Observable is a middleware for Redux which handles cancellation and many other asynchronous side effects by using reactive programming. … RxJS and Most.js are two libraries for reactive programming with which you can handle streams of actions in different ways. … In the following examples, Most.js will be used.
In the past I’ve helped write parts of RxJS, I’ve written xstream, and now I bring a new stream library for JavaScript. This time, it’s a bit different, though, because there are 3 new things:
A reactive stream programming library
An iterable programming library
A specification for callback-based programming
In reality, those 3 are realized in just one thing: Callbags.
The Redux Observable RxJS: Going Epic tutorial will show you how to reactive programming in Redux. The middleware can be used in Redux applications. The example shows it in a React JS app...

This essay attempts to make Conal’s vision more understandable to less mathematically-oriented programmers, and also show how this perspective could be the foundation for a new era of programming, not just with user interfaces, but also multi-node computing, storage, machine learning, etc.
If I was going to sum up my experiences with Vue in a sentence, I’d probably say something like "it's just so reasonable" or "It gives me the tools I want when I want them, and never gets in my way". Again and again when learning Vue, I smiled to myself. It just made sense, elegantly. This is my own introductory take on Vue. It's the article I wish I had when I was first learning Vue. If you'd like a more non-partisan approach, please visit Vue's very well thought out and easy to follow Guide.
When subscribing to observables it’s key to manage your subscriptions. An observable execution can run for an infinite amount of time and therefore we need a way to stop it from executing. If we keep…
