It's unsurprising that we all use Express.js when we need a web server. In this article, I'll show you how I built a source viewer. It's distributed as a npm package view-source and it could render the content of a directory in a nice tree-view style.

I did roughly 50 talks over the years, and for almost all of them, I used Reveal.js. I like it because it's HTML-based. I have complete control of everything and can easily publish the slides online. However, one thing bugs me every single time - the size of my content. I want to use all the available space. This becomes very important when I'm showing code to people. That's why I wrote SimPre. It's a 10KB HTML presentation framework that properly scales and positions my content.

I'm working on a project in my own git branch. At the end of my working day I want to do one thing - run Prettier so my code is nicely formatted before I submit the PR for code review. Of course I know about the VSCode Prettier extension but right now my editor is kinda broken and I don't want to mess with it. I'm still on my branch and I run Prettier from the terminal. All good but the amount of changes that happened is so big that my 50+ loc updates are like a needle in a haystack. It is like that because apparently there are already malformatted files in the project. It is definitely not possible to understand what I did because of so much noise. So ... I want to run Prettier but only on the files that I touched in that particular branch.

The first post in this blog was published on 25th of August 2008. This place was always living on a shared PHP/MySQL hosting. It was driven by a custom made PHP CMS for over 10 years. It is time to move forward and follow my actual language of choice - JavaScript. I spent some time recently migrating it to Zeit and this article is showing my process.

You have no idea how fun is to transpiler JavaScript. I’m digging into that last few weeks and there is a step where I have to transform an AST into valid code. There is one tree node which I really like - sequence expression.

The new ES6 specification of JavaScript simply works better for me. It helps expressing my ideas in a shorter and cleaner way. So, I want to write ES6 everywhere. Even while I’m testing my applications.

Before a couple of months my first book Node.js Blueprints was published by Packt. There are a couple of reviews in Amazon about chapter two. It’s about Express. One of the most popular frameworks in the Node.js ecosystem. The book mentions version 3.0 but the truth is that the code samples are for version 4.0. I feel that I still have to point out the differences and mark these parts of the chapter that are not valid for the newest version of the library.

Node.js is one of those new technologies, which are attracting more and more developers every day. Mainly, because it's JavaScript driven, a lot of people are interested working with it. In this tutorial, I'll show you how to use AbsurdJS together with Express. Express is one of the popular Node.js frameworks. However, the other instrument is really fresh one and I hope that you will find it useful.

I'm a Windows user and I'm working on a ExpressionEngine based site. I'm using EasyPHP as a server and everything works as expected. However, once I decided to upload a file I got "Thumbnail could not be created for the image. Please make sure the thumbnail directory is writable.".

In my company, we have a lot of WordPress sites. Some of them require contact form with captcha field. The short way for solving such task is to use a plugin. However, as you may guess, the add-ons are available for everyone, which means that they could be easily explored and probably hacked. That's why I suggested a simple, custom script, which is developed by us.

Presentation's slides. All my talks at VarnaLab are available here.

I'm going to start a new project with ExpressionEngine. So, I made a short review of the framework's capabilities. The article is available at my account in tech.pro.

I'm blogging for different technologies, but very often I need to add some code in my articles. This little PHP function helps me to keep the text in my

 tags clean for prettify. It simply removes the 
's and keeps the html tags.

1. Moving background layer - sometimes you want to move the background layer. But by default it's locked. So just click twice on the layer and choose "OK" in the popup message. The layer will be transformed to normal layer.
