Current issues

 Debugging is not as great as Visual Studio. You'll need to know how to use the browser's JavaScript debugger fairly well  Not all binding errors show up in the console log sometimes you only see an error when you debug  It is possible to create circular dependency graphs and then your JavaScript will slow to a dog!


 IE developer toolbar  Using HTML inspector  Using JavaScript debugger  Using Network inspector

Risk: Is this mainstream?  Knockout is created as an open source project, by Steve Sanderson. Who is actually a Microsoft Program Manager in the ASP.NET team.  There are other template engines but they aren't as mature - some are still in beta. Knockout is stable and in version 2 already.  Has been proven to work for ASP.NET WCF, ASP.NET MVC, Ruby on Rails, and now SharePoint ;-)  Knockout supports other template engine as plugins.

Risk: looks difficult to learn

 A good grasp of the concepts is the right starting point hopefully I've provided that

 Next, go through the demos and experiment, and use that as a reference to build your own creations

What about if you can't use REST?

 You can use it with the client object model, load SPItem via SP.ClientContext and then use ko.mapping  For SP2007, you can also use which is a JavaScript wrapper library around SharePoint 2007/2010 SOAP Services  You can also use KO with your own custom REST services

Whoa! We don't do dirty Content Editor webparts!

 Take the entire content of the html file, and put it into a sandbox visual web part. This will create a sandbox solution and you can deploy that within your site collection.
