Theme 1: Using Umbraco

16. The KILROY case – Umbraco DK Festival
10,000 destination pages
Problem: create and maintain 10.000 destination pages.
Solution: common destination structure with automatic
creation of sub pages. And onPublish event update of JSON
data files.

What do you do when you need to create a database
of stuff (e.g. staff list, product videos, events, etc.)?

The Umbraco Macro Cache - #h5is
Your are in big trouble, when you entire performance
strategy is the Umbraco Macro Cache…

25. The Law of Leaky Abstractions
"All non-trivial abstractions, to some degree, are leaky.
Abstractions fail. Sometimes a little, sometimes a lot. There's
leakage. Things go wrong. It happens all over the place when
you have abstractions."
Joel Spolsky, http://www.joelonsoftware.com/articles/LeakyAbstractions.html

26. The KILROY case – Umbraco DK Festival
A Robust Caching Solution
1. Use the standard ASP.NET cache
 Problem: when we deploy or when the AppPool recycles, we loose the
cache
2. Use Microsoft AppFabric.
 It provides a distributed, in-memory, application cache service in
separate process than the webserver.
 Problem solved: we have a persistent cache – even when the web
server restarts or the AppPool recycles
We update the cache OnPublish events or after timeout.

4 Quick Tips for Good (Razor)
Performance
…besides using custom caching :-)
27

28. The KILROY case – Umbraco DK Festival
Wisely use HasProperty and HasValue
if (myDynamicNode.HasProperty("myCoolProperty") &&
myDynamicNode.HasValue("myCoolProperty"))
{
int tmpInt;
if (int.TryParse(myDynamicNode.GetProperty("myCoolProperty")
.Value, out tmpInt))
....
}
28

29. The KILROY case – Umbraco DK Festival
Use DynamicNode Extensions and Razor common helper
public static class DocumentExtensions {
public static bool IsValidProperty(this DynamicNode doc, string propertyAlias)
{
if (doc.HasProperty(propertyAlias) && doc.HasValue(propertyAlias))
return true;
return false;
}
public static string GetPropertyAsString(this DynamicNode doc, string propertyAlias)
{
if (!doc.IsValidProperty(propertyAlias)) return string.Empty;
return doc.GetProperty(propertyAlias).Value;
}
public static int? GetPropertyAsInt(this DynamicNode doc, string propertyAlias)
...
}
Usage
int? myIntProp = myDynamicNode.GetPropertyAsInt("mypropertyAlias");

30. The KILROY case – Umbraco DK Festival
Use Children if first level search
Be aware of performance when using DynamicNode.Descendant(docType).
Use "Children" if possible.
For example to get a direct child node :
Don’t use:
DynamicNode dNode =
rootNode.Descendants("myDocType").Items.FirstOrDefault();
You can use instead :
DynamicNode dNode = rootNode.GetChildrenAsList
.Items.FirstOrDefault(x => x.NodeTypeAlias == "myDocType");
30

31. The KILROY case – Umbraco DK Festival
Dynamic notation considered harmfull?
Be aware of performance using dynamic notation like node.DocTypeName =>
same problem as last slide.
To get a direct child node :
Don’t use:
dynamic rootNode = new DynamicNode(xxx);
DynamicNodeList allMyDocType = rootNode.MyDocType; // can have performance issue
// PS : string myProp = rootNode.MyProp is OK is the prop exist
You can use instead:
DynamicNode dNode = rootNode.GetChildrenAsList
.Items.FirstOrDefault(x => x.NodeTypeAlias == "myDocType");

What’s in Our Toolbox?

34. The KILROY case – Umbraco DK Festival
The Basics + a Tip
 Visual Studio 2010 (and Resharper)
 Kiln (Mercurial)
 Shared MS SQL Database
XmlCacheEnabled = false
34

35. The KILROY case – Umbraco DK Festival
Deployment
 Deployment
 Web Deploy from Visual Studio
 XML Config transformations
 Updating Umbraco Doc Types and other settings
 Two approaches:
 Create an Umbraco Package containing every Doc Type, every
template, every macro and so on
 Create an Umbraco Package containing new and updates Doc
Types, templates etc.

Discussion
How do you deploy?
Have you felt the pain of updating an highly utilized
DocType?
