[TrackableEntities.*.js] Support Client-Side Change Tracking for JavaScript Clients

[tonysneed]

Build JavaScript libraries to support client-side change tracking in Single Page App apps. We'll need to create the following libraries:

• TrackableEntities.Common.Core.js
• TrackableEntities.Common.js
• TrackableEntities.Client.js

We could start out by using a tool to reverse engineer from C# to JavaScript. But I would like to write the libraries in TypeScript. We will have to figure out the best strategy for observing entities for property changes and observing collections for adding or removing items.

Hi tony,

While I was researching on the subject, I found several existing change tracking system on top of knockout that I'm currently using in my single page applications. This one looks promising

Are you already working on the 3.0 version ?
I would love to have access to preliminary work and contribute. I really need this JavaScript support as I have to move a huge WPF + STE + WCF + EF application to the web.

I've been spending time getting up to speed on the whole world of JavaScript and learning TypeScript. But it would be great to have some help with this, at least to have a sounding board. What I'd like to do is design the JS change tracker to be independent of any other framework, but then be able to take advantage of things like observables and immutables to optimize performance. Do you have any JS background? I'm coming from a classic C# background, so I've had to made some adjustments. :)

I'm also coming from a c# background and adjusting like you. Fortunately I have some people in my team with a strong JavaScript background that would help.

Sounds good - I'll start on a design doc.
