      There needs to be a metadata generator for POCO classes in projects where entity framework in not used. Reflection can be used to findout properties for generating metadata.

      • Support TypeScript final 1.0

        Now that TypeScript 1.0 is released it is time to update the breeze.d.ts file to support this final release.
        Also it would be nice if breeze.d.ts supports the actual export/import mechanism of TypeScript. Best example: knockout.d.ts

          • Automatically remove from cache items that were deleted by someone else if an Expand clause did not return it

            When multiple users play with similar data and one of the navigation property (to a list of children for example) has hard deletable items, it is possible for one user to load all the children in cache, then for another to delete those children. Then, for user 1, even if he refetches the parent objects with an expand clause to the children, Breeze will currently reattach even those children that were not returned from the server - the deleted ones. There is no easy way currently out of manually clearing the cache or querying directly for each child to check…

            • breeze.js createError function can't handle datajs errors

              My ODataController Post method was updating its entity's CreatedOn property with DateTime.Now value before it's saving to database.

              Apparently datajs doesn't like DateTime.Now value and gives an error with "Invalid date/time value".

              File: datajs-1.1.2.js - Line 2133

              After datajs throws the exception, it falls to breeze.js createError function. However, since it's expecting error.response property, it fails to continue by giving "response is undefined" message.

              File: breeze.debug.js - Line: 15302

              I've updated the function by adding a check for response property;

              function createError(error, url) {
              // OData errors can have the message buried very deeply - and nonobviously
              // this code…

              • Switch to Bluebird promises

                Bluebird promises are orders of magnitude faster than Q promises, they're more modern and they provide a more consistent API for now.

                Switching to them should show improvements in speed as well as debuggability (better long stack traces for example).

                • BreezeJS and Moongose

                  Hi All,

                  I am new to MEAN stack, I am to easily for Moongose based apps and developed rapid prototypes in less than 30 mins, but with Zaa example even though I can run the sample in 10 mins. The concept of metadata generation with respect to MEAN stack very confusing, where as for .NET MVC example I can easily understand.

                  • Validation integration with the FluentValidation framework.

                    DataAnnotation is outdated and fills the POCO with dirt. FluentValidation support would be a great addition.

                    • Specify the version of Express to install in the Zza Example

                      Express v4 differs a bit and will not work with the Zza Example. One recommendation would be to change the instructions until the express code is updated to: npm install express@3.5.1

                      Once the code is updated to support Express v4, remove that specific version from the instructions.

                          • More node.js / mongodb love

                            I fall in love with Breeze, but the support in node / mongodb still needs a lot of work. I can't live with breeze anymore but I can't support .NET.

                            I saw the TODO but wasn't updated since August 2013.

                            Things like associations would change it completely.

                            I vote for some sweet love for those who don't use .NET

                              • Support filters for multi-level relationships with derived types

                                Support filters for multi-level relationships with derived types, as in the currently valid OData 3 filter syntax:
                                BaseModel/derivedmodel.namespace.on.server/DerivedModelProperty

                                Currently this almost works if you specify the property name as above, except that it always defaults the data type of the predicate to string, even if a data type is specified. This is due in part to the syntax failing the RX_IDENTIFIER check.

                                • Tools for meta data creation for breeze not depending on a server-side ORM and tools for ORM-less server-code generation

                                  For me ia server-side ORM for a web application is a wrong cut. I think business logic should go as close to the data as possible to guarantee consistency, protection, and security. This means to me using stored procedures and database functions wherever possible (in a relational environment) and reasonable. In addition, if done right it's arguably unbeatably fast. The role of the Web API should be to provide access to the data across the network but not processing it.

                                  Let's suppose we have to query the database for all open orders for a certain customer including order items and…

                                    I'd like to use MongoDB with ASP.NET Web API. This would require translation of OData queries to MongoDB query syntax in C#, using the MongoDB C# driver.

                                      The related entity never gets found since the key consists only of a single…
