Writing Node Applications as a .NET Developer – My experience in Developing in Node vs .NET/C# (Part 3)

While the previous posts described what one needs to know prior to starting a Node project, what follows is some of my experiences that I came across while writing a Node application.  

How do I structure my project?

The main problem I had when developing my Node application was figuring out a sound application structure. As mentioned earlier, there is a significant difference between Node and C# when it comes to declaring file dependencies. C#’s using statement is more of a convenience feature for specifying namespaces and its compiler does the dirty work of determining what files and DLLs are required to compile a program. Node’s CommonJS module system explicitly imports a file or dependency into a dependent file at runtime. In C#, I generally inject a class’s dependencies via constructor injection, delegating object instantiation and resolution to an Inversion of Control container. In Javascript, however, I tend to write in a more functional manner where I write and pass around functions instead of stateful objects.

Coping with Device Rotation in Xamarin.Android

You think that you have your Android application in a state where you can demo it to your supervisor when you accidentally rotate your device and the app crashes. We have all been there before and the good news is that the fix is usually pretty simple even if it can sometimes take awhile to find.

This has always been an issue for Android developers, but I have found that, due to the unique interaction between your C# classes and the corresponding Java objects, it seems to be a little more sensitive with Xamarin.Android apps. In this post, we will discuss what happens when you rotate your device and cover the different techniques that you might choose to use to manage your application state through device rotations as well as the ramifications of each of them.

Writing Node Applications as a .NET Developer – Getting Ready to Develop (Part 2)

In the previous blog post, I provided a general overview of some the key differences between the two frameworks. With this out of the way we’re ready to get started writing an application. However, there are some key decisions to make regarding what development tools to use as well as getting the execution environment set up.

Selecting an IDE/Text Editor

Before I could write a line of code, I needed to decide on an IDE/Text Editor that I wanted to use to write my application. As a C# developer, I was spoiled with the number of features that Visual Studio offered a developer that allowed for a frictionless and productive developing experience. I wanted to have this same experience when writing a Node application so before deciding on an IDE, I had a few prerequisites:

  • Debugging capabilities built into the IDE
  • Unobtrusive and generally correct autocomplete
  • File navigation via symbols (CTRL + click in Visual Studio with Resharper extension)
  • Refactoring utilities that I could trust; Find/Replace wasn’t good enough

Writing Node Applications as a .NET Developer

As a .NET developer, creating modern web apps using Node on the backend can seem daunting.  The amount of tooling and setup required before you can write a “modern” application has resulted in the development community to display “Javascript Fatigue”; a general wariness related to the exploding amount of tooling, libraries, frameworks and best practices that are introduced on a seemingly daily basis.  Contrast this with building an app in .NET using Visual Studio where the developer simply selects a project template to build off of and they’re ready to go.

Universal Windows Platform – The Undiscovered Country for Windows Desktop Apps

It is unfortunate, but I think Dr. McCoy from Star Trek: The Original Series said it best: ‘Windows 10 Mobile is dead, Jim“…. and just to pile on with one more.

Buried underneath the red shirt like death of Windows 10 Mobile lies the amazing Universal Windows Platform (UWP).

The developer capabilities of the Universal Windows Platform have been documented in many a location.

UWP provides:

  • Full developer parity at the API and framework level across all flavors of Windows 10, Xbox One, HoloLens, and Windows 10 Mobile devices.
  • A simplified install model via APPX bundles.
  • A per-app separation of registry and file systems.
  • XAML controls ‘just work’ across all Windows 10 / UWP devices.
  • Targeting the UWP API set ensures that your app works across Windows 10 / UWP devices.

In my experience, there is nothing weirder than seeing your Windows 10 / UWP app just work on an Xbox One,  in a virtual projected rectangle via a HoloLens, and via mouse and keyboard on a standard Windows 10 PC.

Mobile App Services

Starting on a mobile app can be a daunting proposition.

Your stakeholders at Rex’s Gym really need this app to help drive customer retention, promote the business, and make payments a breeze.

Getting the development environment set up, learning a new language, understanding a wholly different API for screen layouts per-platform, having to go to the Apple Store and buy a Mac (which is the absolutely last thing you thought you would ever do).

Apple WWDC – The Worth of Being There

In this era of travel budget crackdowns and higher than normal oversight into technology budgets, the iOS software engineer can get lost in the shuffle when it comes to training time and opportunities to talk with other members of the iOS development community.

Due to the rise of the popularity of Apple’s iOS platform, Apple WWDC (Worldwide Developer Conference) has become the central rallying point for iOS developers. It seems that the entire iOS community gathers in San Francisco over the week of WWDC. Many developers go to San Francisco over the week of WWDC even if they don’t have a ticket to the conference.

C# vs. Swift – Iron Man vs. Captain America

In Captain America: Civil War we get to see the ultimate battle between Iron Man and Captain America.

It is a battle of simple gutty defense vs. smart weapons and flashy offense, humility vs. brashness, down in the dirt vs. up in the clouds.

To totally geek it up, the same kind of battle exists in the languages that software engineers use today and I believe this is especially true in the battle of C# vs. Swift.

Don’t worry, this really isn’t a versus type write up. If anything I seek to point out each language’s unique strengths, then show how software engineers can get into the right superhero mindset to really use those strengths, and be aware of the weaknesses, to create great solutions.

A Dive into SystemJS – Production Considerations

Previously we have looked at the basic configuration of SystemJS and what happens when you attempt to load modules. What we have covered so far is good enough for a development system, but things are different when you try to push your code to production and performance is much more important. It might be fine for a development system to make XHR requests for each individual script file, but that is not ideal for most production systems. This article will attempt to evaluate the production setup that is needed to attain good performance. [Read more…]

My Trek Through MinneBar 11

minnebar.logoOn April 23, 2016 I attended my first minnebar conference: minnebar 11

I am amazed that content of this quality was presented by community members for free. It was totally worth being inside and roaming the maze-like halls of Best Buy Corporate Headquarters on one of the few sunny Saturdays we get up here in the frozen tundra of Minnesota. The exposure to new technical topics was great, but more importantly experiencing the energy of the people who are active in the Minnesota tech community was the real core of the experience.
