Testing with headless browser (Zombie.js + Jasmine)

I was planning to post this article a few weeks ago, but today I finally finished the examples and I can't wait to share it. We all know that the testing is a big part of our daily tasks and we should use every existing tool to make our lives easier. I really like test driven development and once I found the concept of the headless browsing I started to think that we can automate every single aspect of the testing. In this post I'll show you how to use Nodejs to test a simple php site.

The Flash Builder debugger failed to connect to the running application.

I really don't like FlashBuilder. Mainly because I'm losing a lot of time just to setup the project. Usually when I receive the files I need around 10 hours just to compile successfully. The reasons for those problems are different Flex SDK, different directories' tree, wrong paths, missing libraries or fonts. Today I encounter a brand new type of problem.

Auxilio Chrome extension or how I boost my productivity

I'll be honest and I'll say that I'm a bit lazy sometimes. I'm one of those developers which don't like to repeat same actions again and again. There are dozen of things which I have to do while working on a project. Very often I'm covering the development of several applications and have to switch between them. It's really annoying process. I hate to have many opened tabs in my browser, many consoles or several code editors. I always try to improve my productivity by automating tasks. I think that even switching between opened applications takes too much time.

That's right. I'm not using the terminal anymore. Instead of that I'm using Chrome. Yes, the Google's browser. There is an extension called Yez! that connects to a Node.js module via web socket. It executes the shell commands and returns the result. And even works under Windows.

Feeding the beast at 60fps

The browsers nowadays are smart. They optimize everything and help us to produce better applications. They process our code as fast as possible and even on mobile devices deliver a pleasant experience. However, at the same time, it is possible to write buggy code and make the browser freezing. We are not talking about slowing down the rendering. We are talking about no rendering at all. There are cases where we want so much from the browser that it just can’t handle it.

Using Local Storage as a communication channel

So it's been a few months since I published something here. It’s not because I’m lazy (that’s true though) but because I was working on my second book. Now the book is almost finished and I’ll start actively blogging again. In this article we’ll see how to use the local storage of the browser as a communication channel.

Apache .htaccess for HTML5 push state manipulations

This is a quick post so I document my two hours research. I'm working on a open source library for routing in the browser. Or in other words JavaScript library that uses the history API. The thing is that locally I'm using Apache as a dev server and I wanted all the request to specific folder to be redirected to index.html.

Meet Evala - your terminal in the browser

On my machine I have four applications always open - VSCode, Chrome, iTerm and Slack. I spend most of my time in Chrome and VSCode. My editor is full with awesome extensions and I feel pretty good there. What I am doing for the browser is making sure that I have fewer tabs open and install only extensions that I really use. One thing though I can achieve so far. I can't find the perfect new tab extension.
