It’s been almost a year since I did my first public speaking (related to programming). During that, many things changed including my personal point of view on that profession. It is nothing new that the first steps are the hardest, so in this post, I’ll describe my first feelings, mistakes, and moves which started my personal journey as a speaker. Since I’m still at the beginning of my way, this post will probably evolve from time to time but even thou...

I’m not a big enthusiast of hard-coded values in my apps, mostly because of three things. First, it’s really annoying to change their value if necessary (especially if one is used in many places). Of course, we can use some „find and replace tool” but to be honest I don’t fully trust them. Another thing is that in many cases we have absolutely no idea what do they represent. Let’s say we have the following of code:   PaymentService.Create(or...

As some of you might notice, I’ve not posted any new post since two weeks. There are few reasons for that including my vacations (finally) and other. But the most important one is the fact that I wanted to rest before huge programming competition. If you are not familiar with this even keep reading 🙂  Get Noticed One of the most recognizable Polish .NET developer – Maciej Aniserowicz – came up with really great and simple idea. Why not create some kind of competi...

I’ve been working as software developers since July 2014 and during that time my point of view of IT industry have changed several times. Before starting my career I had absolutely no idea about this profession but even though I loved that! Why? Simply because of my friends who talked about tons of money they were earning, lots of benefits in the office including snacks, coffee, PlayStaion, alcohol and so on. That seemed awesome! Infamously, I must admit tha...

Sometimes it happens that knowing well some tool we suddenly discover an option that seems completely „exotic” but when we sh...

Nowadays, asynchronous programming isn’t something unusual. We all know that when it comes to do some I/O operations or HTTP request, we should do it async. Why? There’re several reasons but two most important  are:Efficiency. In many cases, the code might work faster. That’s because it’s not forced to wait for the result. Instead, it can work on some other stuff and then come back for the response when it’s ready. Simple is that.Comfort. Async improves the comfort of using our applications. We don’t blo...

One thing that surprised me the most about the C# was the fact that it does not support multiple inheritances (which I knew from the C++). How can we deal with that? Of course, we use interfaces, since one class can implement more than one. But quickly we come to the very common problem...

In today’s post, we are going to explore another feature of the Aurelia framework or more precisely aurelia-fetch-client. So, in many cases, it would be nice to perform some specific actions when doing an AJAX request. For instance, before sending a request we want to log it into browser database like PouchDb. A more common example is calling a toastr on some error like 404, 500, 401. The problem with such a scenarios is that many developers duplicate their code in every single request/callback so they b...

When coding web applications we sometimes come to the point when we need to perform some action during user’s navigation. One of the most common examples would be authorization and checking whether the user has appropriate roles. Fortunately, Aurelia provides an access to route pipeline so it’s super easy to add some extra steps Let’s get to work!  Inspecting RouterConfiguration In order to add our custom pipeline steps, we need to create some routing for the application. I won’t describe the whole pr...

In the previous post, I presented to you the Aurelia – new, great JavaScript framework created by Rob Eisenberg. We also used its Command Line Interface (CLI) to create new Aurelia project with all its dependencies, unit tests, and HTTP server. As I announced back then, we’re going to play with CLI to generate some code inside our project. So, let’s get started!Aurelia CLI generator Okay, before our implementation, let’s find out what kind of code we can generate using Aurelia’s CLI. To do that, just ty...
