Miss Piggy - a test runner for Puppeteer

posted in JavaScript on 2021-02-01   puppeteer test runner tagmanager

These days I did (again) a bunch of changes in Google tag manager. This time however was more of a refactoring exercise. So, I had to prove that the tags that were placed before the refactoring exist after the refactoring. And what we programmers do in such cases - we write tests.

Just recently I had to do changes in Google Tag Manager at work. It's interesting how I keep forgetting how everything works. So I finally decided to sit down and write an article about these things. If nothing else I will have a good memory snapshot to remind me what is what.

Create your own Covid-19 data tracker

I'm continuing to experiment with React and TypeScript. The weekend-long project this time was a Covid-19 data tracker. In this blog post I will share how I built c19stats.now.sh. I exposed the data as a public API at the same URL. I guess you, as many other people, follow the situation so you may want to glue your fingers on the keyboard and create something useful around the data. I got lots of fun playing with the diagrams.

React and third-party libraries

posted in JavaScript on 2016-11-27   react tags tag render list jquery plugin extends react component props

React is probably one of the best choices for building UI. Good design, support and community. However, there are cases where we want to use an external service or we want to integrate something completely different. We all know that React works heavily with the actual DOM and basically controls what’s rendered on the screen. That’s why integrating of third-party components could be tricky. In this article we will see how to mix React and jQuery’s UI plugin and do it safely.

Let's write, not generate code. Thoughts about naming stuff.

posted in JavaScript on 2016-07-03   code data html classes naming css good tags

I’m writing code for approximately ten years now and at some point the word “writing” became more important then “code”. I found out that it is easy to generate code but it is difficult to write code. Writing means creating something meaningful. Something that other human beings will read. The code is indeed sent to machines and they do understand ugly code. Not the same for humans though. An important part of our job is to make sure that our code is clear for other teammates.

No back-end blog solution with Node.js and Markdown

posted in Nodejs on 2014-04-22   articles techy md tags article blog html page sidebar content

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.

AS3: Using custom Metadata in Flex (part 1)

posted in ActionScript on 2010-12-28   metadata public flex mycustomclass information metadata tags tag as3 flash utils describetype public function mycustomclass

I'm sure that you've already used metadata tags in your flex applications. There are several reserved keywords like [Bindable], [Embed], [Event] and so on (the full list is available here). The function of the metadata tags is to provide additional information to the flex compiler. For example information about embeding assets, dispatching events. This article doesn't explain how to use the default flex tags (you can learn that from here). It shows you how to create your own metadata tags and how to use them.

A couple of months ago I integrated a nice WYSIWYG editor written in Flex in my CMS. It worked fine, till yesterday I needed to add more features like text formatting and font color changing. As you know the Flex RichTextEditor component adds some additional tags that I definitely don't want to send to the database. So I wrote a simple function to remove these tags.
