Hands On with NodeJS

JavaScript NodeJS

Philly.Net NodeJS event.

Rob Keiser started event and walked through how to setup and run NodeJS manually.  Why might you use NodeJS.  Light weight, Demo API’s, etc.. Some big companies are doing it.  Supposedly, you can use it within Azure if you want.

1.      Go to NodeJS and Install Node on your PC.  Recommended you Reboot once you install product.
http://nodejs.org/
               Install Project
2.      Used Subline Text for Editor (i.e. No Visual Studio in this Demo)
Install http://www.sublimetext.com/

3.      Manually created files to start up a little webserver.  Rob walked through how to create different js files which started up the Server, do Routing, handle different URL requests, etc..  It was challenging to follow along as he was jumping between JS files and I was more concerned with getting at least some of it to work.

Below are some screen shots of a Working Demo, I have created to listen to requests on port 888 and write out to the console what URL’s you were hitting.  I stopped there. Feel free to try this yourself.
Create Server
Create Index
Create Router
Create RequestHandlers

             

 


Option #2 for trying NodeJS

Bill Wolff then started a Demo and used Visual Studio entirely for this work.  Much easier but It was actually good to do to it by hand first and I probably started to understand a little more about NodeNJ doing it myself.  Still, they didn’t a lot of background on NodeNJ and Why to use it. 

1.      Install Node.js Tool for Visual Studio
a.      http://nodejstools.codeplex.com/
** This requires you to Install NodeJS first!! It still needs that to run the product.
2.      Make sure you install TypeScript 1.4 for Visual Studio 2013 as well.  I must not have had this installed as after I created my Project, it failed for it.  I installed TypeScript and then my project built fine.  Last month’s Philly.Net event was TypeScript so maybe everyone else already had it installed.
a.      https://visualstudiogallery.msdn.microsoft.com/2d42d8dc-e085-45eb-a30b-3f7d50d55304
3.      Start Visual Studio
Create Multiple Projects and see how they work and are setup and work.  I recommend you do each on separate and run them in this example so you can review each site separately.
a.      Created Blank Node.JS Web Application
                                                              i.     Similar to Example Above.


b.      Created Basic Node.js Express 3 Application
                                                              i.      


c.      Created Starter Node.js Express 3 Application
                                                              i.     Great Website Example.  3-4 pages, Responsive design with Bootstrap, router pages, etc..

See Websites within Visual Studio


See Starter Express Application running below.  NodeNJ still runs as you can see as that is listening for the page requests.  Views use .jade extensions.  Jade is the Rendering engine, similar to Razor for MVC views.

Create your first Windows 10 IoT background app using Visual Studio 2017: Step by step guide

Create your first Windows 10 IoT background app using Visual Studio 2017: Step by step guide Recently, I went as a Sponsor to a .NET Code Camp and one of the raffle prizes we brought was a Raspberry Pi kit.   I was amazed at how many people wanted this device and many of them said they already had them.   They are fairly inexpensive and can be found on a lot of websites.   A few have a lot of capabilities but for this example, you just need a very basic one. I had picked up a Raspberry Pi soon after you could deploy Windows 10 on it and I’ve been slowly playing with it. I thought it would be extremely helpful to show my application logging through a cheap device as well as monitor a process I was running on my server.   Today I’m basically using it as an email generator. I have a process where when my kids create a new gift they want for their B-day, then I have my background process sending an email to everyone in my family members the gift they...

Performance Review Time!

Its  Performance Time ! Over the past 20+ years, I've both gotten performance reviews and given them in many of them too.  As a manager, it’s something you do once per year. Sure, you might do quarterly reviews or semi-annual reviews to make sure associates are on track but everyone cares about the annual review.  They are stressful for both the associate and the manager.  Everyone asks, why I didn't exceed my goals and/or how does this impact my merit increase. Managers have to make extremely tough decision to do what is best both for the organization as well as to meet the budget guidelines we are given. I’d first like to ask the question, do most people even like getting their performance review?  I suspect not.  I’m guessing most would just like to hear the merit increase and move forward. Why? It’s probably because most performance reviews are so poorly given. I admit, I’ve done it myself.  Most performance reviews seem to be rushed. We ...

Unit Test - Given When Then style

Really nice sample I found on the web that Explains the Given-When-Then Syntax style. The Given When Then style correlates closely to the Arrange Act Assert style for unit testing. Here's an example: [Test] public void RotateAngle_Given27Degress_Returns64Degrees() { //Arrange or Given var someAngleClass = new Angle(); //Act or When var result = someAngleClass.Rotate(27); //Assert or Then Assert.That(result, Is.EqualTo(64)); } Thanks:  http://stackoverflow.com/users/445105/joseph
