What's new in JayData 1.4.0 alpha

OData v4 support (alpha)

JayData team's primary focus is to deliver the best OData client library for JavaScript. We were eager to read the news on OData v4 announcements and ASP.NET WebAPI improvements. As WebAPI OData evolves, we continously add new features. Our first OData v4 implementation build on the new olingo beta library provides testing opportunity to JayData developer community, the production-ready version will arrive in 2015 with many new features, aligned to WebAPI OData and olingo implementations.
Reading v4 endpoints require

Batch query support

Improve the performance of your application and simplify your code by the brand-new batchExecuteQuery() operator! This wonderful feature builds a

batch request for OData provider and builds a promise chain for you on WebSQL and IndexedDB providers.

Retrieve Articles and Categories with a single query
context.batchExecuteQuery([context.Articles, context.Categories]).then(..) 


Retrieve the result of the following queries:
-all articles - JayData uses the toArray() operator by default
-first 5 articles
-first category by passing the firs() operator as a parameter
-count of categories
context.batchExecuteQuery([
 context.Articles,
 { queryable: context.Articles.take(5) },
 { queryable: context.Categories, method: "first" },
 [context.Categories, "count"]
]).then(...)
