Gradient Descent is a fundamental element in today’s machine learning algorithms. We use Gradient Descent to update the parameters of a machine learning model and try to optimize it by that. The clue is that the model updates those parameters on its own. …
When I started using Node.js for building REST APIs on the server side, I struggled a lot with the same question over and over again:
How should the folder structure look like?
Obviously there’s not a perfect or 100% correct answer to this question but after reading some articles regarding…
It’s been quite a while since I wrote an article about how I structure my Node.js REST APIs. The article covered the approach of designing a well-organized and maintainable folder structure for Node.js applications.
So today I don’t want to talk about Node.js APIs, but about the architecture of React…
In this article I’d like to talk about database seeding using Node.js and MySQL: what it is and how to implement it. You’ll notice that it’s actually quite easy and straightforward. For this tutorial, I chose MySQL as the database system but this procedure should also work with any other…

A definition by Oracle (source)
The Stack class represents a last-in-first-out (LIFO)…
Some days ago I wrote a story about how I structure my Node.js REST APIs. However, I didn’t cover any test scenarios in there. So it’s time to catch up on this now.
We’re going to write an unit test for a single API component based on the project structure…
In this article, I will walk you through setting up path aliases in your TypeScript project and show you how to clean up your code.
The problem
In Node.js (or TS/JS in general) you can import modules into your code. This might look like the following:
