  1. 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.

  4. 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).

  5. Support for MongoDB in ASP.NET Web API

    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.

  8. 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…

  9. Breeze + Knockout validation -> new features

    If App uses breeze and ko validation, I suggest to

    add knockout validation rules for every fetched entity as showed in code example (here coffee code implementation for dataPropeties):

    addRules = (breezeEntity) ->
    return if breezeEntity.koValidationRulesAdded
    entityType = breezeEntity.entityType
    for property in entityType.dataProperties
    continue unless property.validators.length > 0
    do (property) ->
    displayName = property.displayName or property.custom?.displayName or property.name
    breezeEntity[property.name].extend
    validation:
    validator: (value) ->
    if breezeEntity.entityAspect.validateProperty property.name, {displayName: displayName, entity: breezeEntity}
    @message = ""
    return true
    else
    @message = breezeEntity.entityAspect.getValidationErrors(property.name)[0].errorMessage
    return false
    message: ""
    return
    breezeEntity.koValidationRulesAdded = true
    return

    this code allows:
    1) to validate single property with usage of all…

  10. Validation integration with the FluentValidation framework.

    DataAnnotation is outdated and fills the POCO with dirt.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

  11. 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.

  12. 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.

  13. 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.

  14. 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…

  15. 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.

  16. 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…

  18. 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…

  19. 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.

  20. Support jqLite

    Single Angular incorporates the core functionality of jQuery in its internal jqLite, it would be helpful if Breeze could use jqLite so that the dependency on jQuery could be eliminated in Angular projects.
