      No news yet. BTW, there is a lively debate about whether there is any actual advantage to making async calls to a database. The argument against is that a RDB is not easily scaled and is often the bottle neck. Throwing even more requests at the RDB could create more trouble and wouldn't actually improve overall application throughput. Be careful what you wish for.

        Agree that this is a good idea. Why not contribute it yourself?

          Michael,

          We're definitely looking into this. In the meantime, please have a look at this previous request:

            Recent updates to Visual Studio 2012 (specifically Update 3) have broken the Breeze SPA VSIX templates, and with Visual Studio Update 4 just around the corner, we expect unanticipated changes to Visual Studio will break the templates yet again.

            We plan to update the Breeze SPA templates to be compatible with Visual Studio 2012 Update 4 shortly after it goes live.

              Related to this topic, Infragistics blogged about how they are using one of their solutions to enable grids in SPAs.

              It's worth checking out:

                  The reason we create a single POST for saves with WebApi is that it is by far the easiest and most compact way to send a complete bundle of entities to the server for the purpose of a save. However, nothing in Breeze is tied down to this. In fact, the Breeze OData adapter does exactly what you suggests, except that in order to accomplish it we have to create a multipart-mime message that internally contains a collection of put/patch and delete requests. The multipart-mime is necessary for transactional support. We do it this way because this is what the OData spec specifies.

                  In your request, you seem to be saying that the developer could use a REST API for saving a single entity, and a batch API (WebApi or OData batch) for saving all changes at once. This seems like the road to partial saves and all their problems.

                  I like the idea of supporting REST urls. Our WebApi implementation supports GET in a RESTful manner (e.g. /breeze/northwind/Customers), and we could add support for the getting a single customer via /breeze/northwind/Customer/4321.

                  Updates are another matter. The answers to this SO question about REST transactions imply that you should treat a “transaction” as its own resource. However, the answers disagree in the specifics. Some suggest that the transaction should first be created, then the resources added to it in separate requests, then committed in a final request. Painful.

                  http://stackoverflow.com/questions/147207/transactions-in-rest

                  We already give SaveChanges its own URL, to which we POST, which appropriately captures the non-idempotent semantics of the save.

                    Roger that. Moving this back to under review.

                    Frizzy, will you please give us more information on your use case for this request?

                    Given that Breeze supports auto-generated keys, and Breeze supports multi-part keys, what scenarios do you find using both at the same time to be helpful?

                    Thanks,

                    John

                      It isn't KO specific, but this our validation topic (and the DocCode sample) might help you:

                        Ed, can you provide a bit more information on what you'd like to see. A use case perhaps?

                        Thanks,

                          You can reuse the same EDMX with Breeze and DevForce (provided you're not using inheritance or complex types at this time). The one down side is that you can’t share the server-side query and save interceptors.
