How I squeezed two hours and a half

posted in Must-see on 2014-11-21

Usually I don't write such articles but this time I'll share my story. I was going to fly from London to Bulgaria. The flight is two hours and a half which is (by my opinion) enough to get bored. When I was traveling from Bulgaria to London I used my phone a lot. I read lots of stuff for reactive programming, played few games, ate some snacks. However, for the way back I wasn't prepared.

Unit test your client-side JavaScript

posted in JavaScript on 2014-11-20

I don’t think that we have to discuss the importance of having tests. That’s not something that we add to the project in addition. That’s something that the project is based on. And because testing is so important we have bunch of tools in our disposal. We all know (I hope) how to test our back-end code. However, once we move to the front-end is a bit different. At the moment we are working on a big single page application and testing is one of our main focuses. In this article you will see how to unit test our client-side JavaScript.

My front-end performance case study

posted in Must-see on 2014-08-25

I’m reading and watching a lot of interesting things regarding client-side performance. I’m interested in the browser’s processes happening before and just after the page’s load. There are tons of stuff to think about. Before a couple of days, I joined the online workshop of Vitaly Friedman. I had a great time and learned some clever facts about performance optimization.

CSS variables are here for ages

posted in CSS3 on 2014-08-13

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 Blueprints book - second chapter's clarification

posted in Nodejs on 2014-07-30

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.

Feeding the beast at 60fps

posted in JavaScript on 2014-07-23

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.

The three rules of the good CSS architecture

posted in Must-see on 2014-07-15

CSS is easy? CSS is messy! And as a project grows, it only gets messier. You find yourself throwing !important at everything or fighting with long selectors just to get a style to overrule another. Projects eventually become unmanageable and you pray for the next redesign when you can burn it all down and start from scratch.

Usersnap - the holy grail of bug reporting

posted in Must-see on 2014-07-15

The bug reporting is something very important for us. As developers, we produce code that should work everywhere. Not only on our machines. No matter how many times we test our application it often happens that it does not work properly for the client. We all know how helpful is an email with text “It does not work. Fix it ASAP!”. Usersnap is amazing tool that removes the gap between you (the developer) and the non-techy guy from the other side.
