I ❤️ markdown. I like its simplicity and minimalistic API which is good enough to cover most of needed HTML markup. At least for textual content. At work we have a small node based microservice that delivers data from Contentful in exactly markdown format. It's all working well but we started having cases where part of the text is in Contentful and the other part is in that microservice. For example when we have a button with a catchy design. We want to content manage the label of the button but the actual markup to be on our side.

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.

Long long time ago in a kingdom far far away there was an app. The app was supported by the well known React and Redux families but there was a problem. It was damn slow. People started complaining and the app had to do something. It had to deliver its content quickly so it provides better user experience. Then the server-side rendering was born.

One of the things that I really like at work is the fact that we spend time in research tickets. We have unknowns and we make a research to find out more information on particular topic. We then base our decisions on the results. Recently we had to decide whether to use an <iframe> for a third party widget development. I feel that the collected information may be handy to someone else so I decided to write it down here.

Every front-end developer that starts reading about CSS preprocessors thinks “Oh, finally variables in CSS". Indeed, the ability to create and use variables in CSS makes our code much more flexible. However, I think that there is no need to use a preprocessor to create flexible stylesheets.

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.

We all know what responsive means nowadays. We, as developers, normally develop responsive applications. There is a dozen of instruments helping us achieving our goals. Some of us use extensions and even pay for them. However, I'm using one thing - Google Chrome browser. In this article, we will see what the Chrome's capabilities for testing responsiveness are.

Before a couple of weeks I published Techy. It's a flat CMS based on Node.js and Markdown. I made it because I wanted to write my articles in Markdown format and avoid the annoying publishing workflow which I'm using now. I feel that it's not very clear how Techy works and decided to create a simple blog illustrating the processes.

The off-canvas menu is pretty popular nowadays. You know, the little button in the right upper corner which opens the navigation with a slide-in effect. That's what we are going to build in this article. The interesting things is that we are not going to use CSS neither HTML, only JavaScript.

I'm currently working on the official site of AbsurdJS. There are a lot of code samples out there and I wanted to present them in JSBins.

I just answer on that question in StackOverflow. I think that this is a common quetion so it worths writing about it.

These days I'm working on this little thing. It's a CSS micro framework following atomic concept. My preprocessor of choice is SASS. That's why I wrote several articles on this subject. Today's post is about media queries mixin.

I just started using SASS and I love it. A bunch of cool features, which will help me to improve my CSS coding. @content directive is one of them.

By definition :before and :after are CSS pseudo elements. You can use them to insert something before or after the content of an element. There are some great articles giving the basics, but I wanted to write down a blog post for the real use cases. Or, at least, to show what I'm using them for.

In this article I want to share my thoughts regarding responsive design. I made several talks on this subject and this post is some kind of summary. The article presents concepts like mobile first and design in the browser.

I'm currently working on a Google Chrome extension and I need to run a JavaScript in the context of the current page. The obvious choice for such a logic is the content script. However it is not so easy, because the content script has an access only to the DOM of the current page. It can't run global functions or use global objects.

I'm working on a chrome extension which accepts user text, work with it and output the result in a div. I used jQuery in the beginning, for several tasks, but later I decided to remove it and deal with pure javascript/DOM manipulations. The output div was filled by using innerHTML property and everything was ok. But, at some point, I sent few buttons to the user and he has to interact with them. However, once I update the div's content the event listeners are detached and the buttons became non-functional.

As you may know I just updated my web site. There are five columns which nicely slide up and down on a lower resolution. In other words, accordion-like navigation. Initially I made this effect with JavaScript. But there was a bug and I decided to use pure CSS. I wanted to define everything in CSS classes which to add or remove. The idea wasn't bad except the fact that every column contains dynamic content and I wasn't able to set the exact height when the column is slided down.

By my opinion one of the biggest problems in programming are dependencies. If you want to have a good well written application you should avoid dependencies between your modules/classes. There is a design pattern which could help and it's called Dependency Injection (DI). It allows you to inject objects into a class, instead of creating them there.

When you are opening a site via https protocol and there are items loaded with absolute addresses started with http some browsers, like IE, throw a message This page contains both secure and non-secure items. It is really annoying and if the user decides to can prevent these items of showing and he can brake the whole layout or some functionality.

Sometimes it is necessary to present your data in format which is popular and easy to work with. In most cases the CSV format will fit perfectly you and your clients, but sometimes you have to export the information in XLS file. These several functions will help you to do that.
