Lazy Loading your JavaScript Hierarchical Model

Mike Griffin — Mon, 30 Jan 2012 05:05:15 GMT

This was a quick video that was just made showing the full hierarchical object model being lazy loaded in JavaScript using entityspaces.js. It’s pretty cool stuff. It’s exactly like using the EntitySpaces Hierarchical Object Model in C# or VB.NET. It works nicely with Knockout as well.

From mobile devices to large scale enterprise solutions in need of serious transaction support, EntitySpaces can meet your needs. Whether you’re writing an ASP.NET application with medium trust requirements, a Mono application, or a Windows.Forms application, the EntitySpaces architecture is there for you. EntitySpaces is provider independent, which means that you can run the same binary code against any of the supported databases. EntitySpaces is available in both C# and VB.NET. EntitySpaces uses no reflection, no XML files, and sports a tiny foot print of less than 200k. Pound for pound, EntitySpaces is one tough, dependable .NET architecture.

What you can do with 7 lines of JavaScript?

Mike Griffin — Sun, 22 Jan 2012 17:38:09 GMT

Our entityspaces.js “Javascript (ORM) Data Access Framework Based on Knockout” is really becoming solid. We have written a full featured demo that will really surprise you considering we only had to write 7 lines of JavaScript code to Save, Add, Edit, RejectChanges, and Delete data. The Example is a pure HTML/JavaScript page. While it is true that there are more lines of JavaScript in the EXAMPLE PAGE that code is merely dealing with the Grid and MVVM view model, but even that code is trivial. Our entityspaces.js JavaScript classes (Employees in this example) and our WCF JSON Service were generated by EntitySpaces Studio in seconds. To see the 7 lines of required code see the code next to each button.

Features

Built upon Knockout and the MVVM Model
Supports WCF JSON Service and RESTFUL API's
Supports Full Hierarchical Data Models
Two Providers, either pure XHR or JQuery Ajax (you choose which one you want to use)
Tracks Row Level and Column Level Dirty State
Tracks Original Values so Edits can be Cancelled via RejectChanges

You can use your browsers “View Source” menu to see the full source for the page.
