WHY DID I CREATE A YOUTUBE CHANNEL? 🤦‍

/ Software Development / Opinion

Let me walk you through the reasons I decided to create this channel? Why did I create yet another technical tutorials channel? Don’t we have enough already? If you’re curious, stick with me until the end to find out what’s so different about the content on this channel. I’m going to tell you a personal story to better illustrate my reasons and hopefully you’ll have some fun while viewing / listening to it. Read more

How to set default values using ES6 destructuring assignment

/ Software Development / Productivity

Here’s a trick I use to render a default page when a parameterized Express.js route is called with no parameter. You will learn how to set default values when using the destructuring assignment with objects. The destructuring assignment is used to unpack values from arrays or properties from objects, as you will see in this video.

Automatically fix ESLint code validation errors in Visual Studio Code

/ Productivity / Software Development

Just found this very interesting feature in Visual Studio Code. It turns out that if you break a style rule, and you get a warning from ESLint, if you click on the lightbulb that appears on the gutter, near the line number where the error is, you get a “Fix problem” option. At first, I wasn’t sure if this was built into VSCode or in the the ESLint extension I’m using. Read more

Improve your Node.js code readability with this simple trick

/ Software Development

In this short article I plan to share with you a simple trick I use to make my Node.js code read better. It’s not wizardry so don’t get discouraged by the “trick” in the title. Here’s a regular Expressjs route handler executing a database interrogation using Mongoose: router.get('/user/:userId',(request, response) => { User.find({ id: req.params.userId }, (error, data) => { if (error) { return response.status(500).json({ status: 500, error: 'The query failed', }); } if (!

Technical advice for startups

/ Software Architecture / Software Development / Productivity

TL;DR Stop creating monoliths. Stop the brainless, head-first dive into development. Buy the cheapest notebook and some pens and start scribbling. You’ll thank yourselves! The story From time to time, I get the chance to interact with tech startups and I formed the nasty habit of asking about their codebase. Whenever I ask this question, I get two types of answers depending on who’s answering: The CEO, or any non-technical C-level person, almost always complain they’re moving too slow because of poorly written code.

jQuery, Babel, React Native and the importance of making mistakes

/ Software Development / Opinion

It wasn’t very long ago when we didn’t have all these generators, scaffolders, bootstraps etc. Not long since we used to include a small library into every project. You got it right, people, I’m talking about jQuery. Actually, the article is not about jQuery. The title can be regarded as a clickbait but I had to draw your attention to something important. Consider this article a parallel between jQuery and the web platform’s current state of affairs. Read more

X in a box - containers for developers video series?

/ Software Development / Software Architecture / DevOps

For quite some time I wanted to help developers better understand Docker containers. I’ve been working with containers for the past 2.5 years and like most of you, I was just a full stack JavaScript developer. I had to learn how to use Docker containers with no previous knowledge and little or no guidance. It was like being thrown off a plane with an umbrella instead of a parachute. This wasn’t necessarily a bad thing. Read more

React Native + NavigatorIOS + Bad Habits = 2 wasted hours

/ Software Development

Long story short: I’ve never worked with React Native and wanted to give it a spin. Setup was a breeze, and I was able to get the app to work in the iOS simulator in a matter of minutes. What came after, is a story about bad habits. A couple of stack traces and some style updates later, I said to myself: “Does this thing have navigation?”. So I found NavigatorIOS in the docs.

Working with Vue.js after React and Angular

/ Software Development / Opinion

I wanted to work with Vue.js on a “real” project for quite some time. Last night, I decided to migrate a very small portion of a larger project to Vue. In the next week or so, I plan on publishing a small series of articles about this experience. Setup Very quick setup, no headaches. The guide is straightforward and the fact that they also offer a CLI makes the experience more enjoyable for command-line junkies like myself. Read more

How are regular functions and function expressions different in JavaScript?

/ Software Development

I’ve been asked this question countless times during mentorship meetings, meetup networking sessions and forums. – What is the difference between assigning an anonymous function to a variable and a regular function? To know this difference the only requirement is to know how hoisting works in JavaScript. TL;DR – Hoisting The main difference between a function expression and a regular function is the following: Regular functions are hoisted to the top of the scope, with their full body whilst function expressions are hoisted like regular variables.
