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.
Reactive paradigm is a declarative way to manage changes in application status (versus traditional imperative programming), based on the concept of event streams.
I'm a huge fan of typed functional programming. I've also been working with JavaScript and Node.js for a lot longer than I've been working with languages like Haskell. So when we were building out the server for Ellie I wanted to use what I've learned studying functional programming while sticking with a language and platform familiar to web developers. A huge theme of my programming practice so far has been understanding how to represent effects like database calls and network requests in a way that is still testable.
I’ve found it really hard to find good examples on the internet on how to build an API using Node.js and Postgres on Lambda and API Gateway so I’ve decided I’ll make my first blog here on Medium…
Once we were over the infamous Haskell learning-curve, we began looking for functional programming, immutability, and types everywhere! Given that one-third of our code runs in the browser (via Angular v1 — for now!), it is only a matter of time before we make the switch to typed-FP for front-end development as well.
I have recently started playing around with PureScript. In this post I want to document some of the learnings I had when writing a first tiny app with PureScript and Pux. As I walk through the code of the app I'll cover the basics of Pux. I will not attempt to provide a full tutorial here, nor will I cover the very basics of PureScript. But I will provide some pointers to useful resources where I found some.
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...
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…
