Technical KnockOut

The other day I was working on a little demonstration of using OWIN to serve local files, use dependency injection, and server Web API in a modern SPA (Single Page Application).

Almost as an afterthought, I decided to use KnockoutJS and jQuery from a minimal HTML page. This was overheard by colleagues, and a firestorm erupted...

"You should have used AngularJS instead; It would take less lines of code."

So I pulled down AngularJS and changed my demo to placate the angry threats wishes of the religious zealots thoughtful developers at my desk.

For the record, this is the code I wrote using KnockoutJS and jQuery:
and here is the AngularJS version:

Trying to provide equally readable formatting, the Knockout solution takes one less line of code even though you are loading two JavaScript libraries. The only fair way to count lines is to count semicolons. Both have three. That's a tie.

What about the size of the libraries being loaded. Well, Angular includes a jqLite, a stripped down version of jQuery. It takes 50.5 kb. KnockoutJS takes 20.9 kb and jQuery 28.9 kb for a total of 49.8 kb. You can't say either one has much of an advantage there

I'm not going to argue the merits of one library over another. I think they serve different purposes. For the purposes of my very simple demo, I have a hard time seeing where either has any real advantage.

So, the answer is... do whatever makes you (or the barbarians at your gate) the most happy.

If you want to look at it, here is a complete GitHub repository with my solution.

Database Projects, SQL Unit Tests, and TeamCity

Image
Continuous Integration  is a really good idea, especially when you are working with a team of developers. There are lots of tools out there that can help your team build better quality into your application. TeamCity by JetBrains is one such tool that has been around for awhile; specifically, it is the one that my company uses. Visual Studio has Database Projects   SQL Server Data Tools  to address some of the inconsistencies that developers face when using a database as a storage layer; Things like version control and consistent deployment. It also includes SQL unit tests , which fills a huge gap if any  of your logic is in the database. Many organizations moved away from logic in the database years ago because it was tricky (at best) to verify logic on the data tier, of course, they were also making changes directly to the database itself... but I digress. If you are using SQL Server Data Tools, and run your unit tests locally, it is a joy to behold. Your data...

Building nice XML from SQL Server Tables

The XML functionality of SQL Server is vast, however, the best subset of that functionality that I've found may be demonstrated in the following example: Unfortunately, the example result is listed before the code. Join all the desired tables together Set the desired root element Set the path to an empty string to avoid an extra XML element at the root of each resulting row Provide an XPATH name with attributes for each of the desired columns (select * doesn't work well) Keep all the selected columns together by XPATH name or you'll split your xml attributes See my next blog entry for my best way to shred the xml

Brent: Programmer. Gamer. Cheapskate. All around good guy.

So... not being one that can leave a sore spot alone, when Brent Brown sent me an email Brent his "preferred" blog link so that I could update the link I had created to Stubenville , I naturally couldn't just update my previous blog entry. I needed to take the opportunity to pour lemon juice, salt, and vinegar into the wound until it became a pulp of agonized flesh. It may be because that's the way I am, but it may also be because Brent really needs this kind of opposition in his life. After all, he has a wonderful wife and cute kids, but as far as I can see, nobody that really gives him the harassing that he needs to keep his life in balance. That's where I come in. I don't know what the big deal is... after all, I liked the Stubenville (not Stupid-ville, that's a whole other wound that needs opening from time to time) thread. However, since he isn't there any more, I suppose that it has a limited shelf life. So, if anyone actualy reads my blog, you...
