$("#movieTitleView").kendoMobileListView({
  dataSource: Northwind.Products.filter("it.Category_ID ==1").asKendoDataSource(),
   template: ...
});

Use JayData EntitySets as a read/write Kendo dataSources - and automate crud.

$('#grid').kendoGrid({
   dataSource: northwindContext.Products.asKendoDataSource(),
   editable: true,
   toolbar: ["create", "save", "cancel"],
});

WebAPI provider

Do you want to access ASP.NET WebAPI services from JavaScript without additional server-side modules? No problem! WebAPI provider for JayData is here.

Todo.setStore('remote', { name: 'webApi', dataSource: '/api/Todos'});
Read the folloging blogpost to learn how can you use JayData with WebAPI: How to use JayData with ASP.NET Web API - I

!! InlineCount() operation in OData provider
Write OData queries, which returns the not just the records but the number of records. This feature makes SharePoint 2013 app development much easier.

Northwind.Products
  .withInlineCount()
  .filter('it.Name.startsWith("Che")')
  .take(1)
  .toArray(function (items) {
    console.log(items.totalCount);
}

Easy paging using next() and prev()

JayData was able to retrieve a portion of records from the server/local storage by take() and skip() functions, now you are able to retrieve the next the previous chunks by accessing the next() and prev() functions of the resultset.

context.Todos.take(5).toArray().then(function (result) {
  result.next().then(function (nextResult) {
    console.log('next 5 todos', nextResult);
  });
});

context.Todos.take(5).skip(10).toArray().then(function (result) {
  result.prev().then(function (prevResult) {
    console.log('previous 5 todos', prevResult);
  });
});

Other new features:

type.create() factory methods in type system
Facebook provider supports length()
describeField, define field if not exsits.
Itemstore API improvements, usability

Changes

JayService: fullRoute from req.baseRoute

Northwind.Products
  .withInlineCount()
  .filter('it.Name.startsWith("Che")')
  .take(1)
  .toArray(function (items) {
    console.log(items.totalCount);
}

Easy paging using next() and prev()

context.Todos.take(5).toArray().then(function (result) {
  result.next().then(function (nextResult) {
    console.log('next 5 todos', nextResult);
  });
});

context.Todos.take(5).skip(10).toArray().then(function (result) {
  result.prev().then(function (prevResult) {
    console.log('previous 5 todos', prevResult);
  });
});

Other new features:

type.create() factory methods in type system
Facebook provider supports length()
describeField, define field if not exsits.
Itemstore API improvements, usability

Changes

JayService: fullRoute from req.baseRoute
upgraded to datajs 1.1.0 (custom modifications has been merged to patched js)
sqLite changed db logic
EntityContext-ItemStore refactor
storeToken can be function or object with typeName and args (for context create)
addMember() can define static properties, with third true parameter
static properties has store- and retriveProperty function, backingfield for value

Fixes

sqLite provider, db drop if changed creation mode
field convert from string: '' value is undefined, not an Exception with invalid value
jaydatamodules validate.js: call fromBinder withour data convert
OData provider: save null value on navigational property, to clear reference
mongoDB regex field operations unary NOT fix

WebAPI provider

Do you want to access ASP.NET WebAPI services from JavaScript without additional server-side modules? No problem! JayData is here and provides you the unified CRUD syntax, which makes you able to change your WebAPI implementation to OData later.

Todo.setStore('remote', { name: 'webApi', dataSource: '/api/Todos'});

!! InlineCount() operation in OData provider
Write OData queries, which returns the not just the records but the number of records. This feature makes SharePoint 2013 app development much easier.

Northwind.Products
  .withInlineCount()
  .filter('it.Name.startsWith("Che")')
  .take(1)
  .toArray(function (items) {
    console.log(items.totalCount);
}

The withInlineCount() applies the OData "allpages" parameter by default, but you can specify withInlineCount("none"), which is equivalent to leaving the withInlineCount() from the query.

Easy paging using next() and prev()

context.Todos.take(5).toArray().then(function (result) {
  result.next().then(function (nextResult) {
    console.log('next 5 todos', nextResult);
  });
});

context.Todos.take(5).skip(10).toArray().then(function (result) {
  result.prev().then(function (prevResult) {
    console.log('previous 5 todos', prevResult);
  });

ItemStore API v2

Since now ItemStore API can be used on each providers including local and cloud storages. We want to keep both ItemStore API and JavaScript Language Query (JSLQ) in the future, so you can choose your data access syntax according your taste.
We've extented the ItemStore API with filtering functionality as well. You can choose to use jQuery 1.8.0+ or Q promise/qDeffered.js to make it happen.

Entity operations for LocalStore provider

Query HTML5 localStorage like nobody else before! Filter objects using the following operations startsWith(), endsWith(), contains(), length(), substr(), toLowerCase(), toUpperCase(), trim(), ltrim(), rtrim()

Entity operations for IndexedDB provider

Forget the crazy cursors of IndexedDB API and filter, order, project and page records using JayData ItemStore API or JSLQ, because orderBy(), take(), skip(), first(), single() operations are supported by IndexedDB provider! How cool is that?!

Node.js support on Windows

According to your feature requests JayData can be used on Node.js in Windows environment, too. Install the JayData library from NPM, type require('jaydata') and publish data on the server-side or consume data (with static schema in this case).
