  4. Better non MS support

    Compared with other data client libraries Breeze is way ahead but it is still heavily tied to MS. It says it supports most dbs out the box but this is a bit misleading as you need a .NET provider which really means Windows. I've mainly worked on MS technologies but recent requirements mean a lot of our systems run on Linux and I'd like to use Breeze for this.

  5. Fix Navigation Property Update When Changing a Composite Foreign Key

    In an entity that has a navigation property based on a composite foreign key (i.e. based on more than one foreign key properties), when setting one of the FK properties, breezejs tries to update the navigation property, however it searches for the foreign entity using a single key instead of a composite key, so it never finds the property.

    To see what I mean and for a possible fix, please refer to breeze.debug.js (v.1.4.8) lines 4907 and 4908:
    key = new EntityKey(relatedNavProp.entityType, [newValue]);
    relatedEntity = entityManager.findEntityByKey(key);

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

  6. Support Web API 5.1.x

    When attempting to install the Breeze.Server.WebApi2 from nuget, this error is reported, and installation fails:

    Install failed. Rolling back...
    Updating 'Microsoft.AspNet.WebApi.Core 5.1.1' to 'Microsoft.AspNet.WebApi.Core 5.0.0' failed. Unable to find versions of 'Microsoft.AspNet.WebApi.WebHost, Microsoft.AspNet.WebApi.Owin' that are compatible with 'Microsoft.AspNet.WebApi.Core 5.0.0'.

  7. 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.

  8. optimize/compress data/bandwidth using nested arrays of values only

    Instead of current JSON format used to send data from server to client, optimize it so that only values are sent in an array (or nested arrays) - no need to send field names if schema is available, otherwise send a separate mini-schema (list of fields/types) along the data. Decode it on the client back to the current structure.
    This is especially important when trying to limit the data sent back using Select on the server (anonymous entities), each row includes a complete data type as a very long string - with many rows, this adds substantial overhead (almost always…

  10. EmailAddress validation issue

    Hello. You copied regex from .Net EmailAddressAttribute to client validation emailAddress. Server-side validation is with ignore case option, but on client - without it, so email with any uppercase letter is invalid.

  11. I still cannot find a good example of querying locally...

    it's the only reason left to continue with Breeze...and we can't get it to work without defining our own type. I looked through the sample code you have and there isn't an example with local querying.

  12. Access EntityManager from Node.JS as server side data access API

    I'm interested in being able to use the Breeze.js EntityManager and query capabilities within a node console service to access a remote Data Service that exposes an BreezeJS/OData compliant RESTful endpoint.

    We currently have a Data Service implemented using Node.js, MongoDB and the Breeze.js breeze-mongodb module.

    We have web browser hosted clients that access the MondgoDB using the Breeze.js client API (EntityManager) and the Data Service described above.

    I need to create another Node.js service that can access the same MongoDB database that the web browser hosted clients do, and for consistency/simplicity I would like to use the same data…

  13. .withHeaders for specifying optional headers to pass along

    If we have specific headers we want to pass along for certain calls and not others we don't have the ability to easily handle that when we are using an OData adapter. I've seen implementations where this is handled by setting values on the oData default http client, but that makes the setting occur for EVERY call when I would like to have a more granular level of control to be able to pass along headers in certain scenarios.

  15. support odata minimalmetadata

    breezejs does not support use of minimalmeta and jsonlight resposes are too big. I tried using

    //odata.defaultHandler.accept = 'application/json;odata=minimalmetadata';
    //odata.jsonHandler.useJsonLight = true;

    all operations but delete work. because delete depends on the full meta data

  16. Improve the error reporting when the json returned by breeze doesn't include fields it needs ie. $id $type

    Currently we get an obscure error message, such as "object #<object> has no method getproperty"...would be nice to get something like "JSON result is not in the required format, Breeze can't map your entities, $id and $type are required"

  18. Support Entity Framework 6 with WebAPI 1 / .NET 4.0

    Current EF6 support requires WebAPI 2, which only runs on .NET 4.5. Please consider adding support for using EF6 with WebAPI 1 on .NET 4.0 for those of us with old Windows 2003 Servers.

  19. Http POST for Queries to enable advanced search screens

    When creating advanced search screen it's easy to hit the url limit of 2000 approx characters, certainly when performing projection queries.

    Allowing queries to be sent using Http POST would remove that restriction.

  20. POST

    Allow POST for Queries when using DataJS. Breeze.AjaxPost.js Adapter only works when using Breeze Controller not when using regular OData Web API.
