Today I’d like to share with you something that I’ve been working on for some time – the first three episodes of my new video course. The course is dedicated to functional-reactive programming in Angular.
Advanced functional programming in TypeScript: Maybe monad
With this post, I would like to start a short series about monads. If you are familiar with some functional programming techniques in JavaScript (such as immutability or pure functions), this is a great next step to go deeper into this amazing paradigm. Regardless of whether you’ve never heard about monads or have heard about them but never really understood them, this series will strive to explain then in simple, practical terms.
Creating Angular NPM packages with ng-packagr
In this short post, I would like to share some of the experiences I’ve had when creating an NPM Angular package using ng-packagr.
TypeScript: Building an interpreter with discriminated unions
In the previous post I’ve explained what discriminated unions are in the TypeScript language. We’ll now look into a classic example of how this concept can be applied to a real-world scenario – building an interpreter.
TypeScript: Precise domain modeling with discriminated unions
In this post, we’re going to look into an interesting feature of the TypeScript language. It’s called discriminated unions and is also known as algebraic data types. The latter name comes from Functional Programming paradigm where such types are used very heavily.
NgPoland 2017 conference summary
Last Tuesday I gave a talk about using Functional Programming in Angular at the NgPoland conference – the biggest Angular conference in Central and Eastern Europe (and big it was – over 600 Angularians in one place). While I’m planning to write an article based on my talk, first I would like to post some notes from the other talks I saw.
Change detection in Angular versus AngularJS
Change detection is the mechanism responsible for data binding in Angular. Thanks to it you don’t need to manually manipulate the DOM tree. Instead, you can make changes to the model and they are automatically reflected in the view.
Using RxJS with Angular: part 2
In the previous post about Angular and RxJS we discussed the AsyncPipe and how it can be used to consume Observables in Angular templates. This time we will focus on the essence of functional-reactive programming. Let's see how we can reinvent the way we look at how data flows in our program.
Using RxJS with Angular: part 1
Recently I wrote about using RxJS as part of my Functional Programming in JavaScript course. Let’s see how to combine RxJS with the Angular framework.
Real bug story: very long-running jobs in Hangfire
Hangfire is a great tool which can help you with doing background processing in .NET web applications. It’s great for tasks such as background import or asynchronous processing of some events or requests.
