    2.0.0-alpha.13 • Public • Published


    Breeze data management for JavaScript clients.
    See the docs for more info about what Breeze does and how to use it.

    Install from npm

    npm install breeze-client@next

    Build using ng-packagr

    Run npm run build. This will create files in the '\dist' dir. The directory structure is the Angular Package Format.

    adapter-*/                Breeze adapter definitions (*.d.ts) for ajax, data service, model library, and uri builder
    bundles/                  Breeze and adapter libraries in UMD
    esm5/                     Breeze and adapter libraries as ES5 modules (separate source files)
    esm2015/                  Breeze and adapter libraries as ES6 modules (separate source files)
    fesm5/                    Breeze and adapter libraries as ES5 modules (combined source files)
    fesm2015/                 Breeze and adapter libraries as ES6 modules (combined source files)
    spec/                     TypeScript definition files (.d.ts) for tests
    src/                      TypeScript definition files (.d.ts) for source
    breeze-client.d.ts        TypeScript definition file (links to the files in src/) 
    breeze-client.metadata.json      Metadata for Angular AOT
    index.d.ts                Main entry point
    LICENSE                   MIT
    package.json              Package metadata
    public_api.d.ts           Main entry point

    It will also create breeze-client-{version}.tgz in the main directory. This file can then be installed in a project using

    npm install ..\{path}\breeze-client-{version}.tgz

    Build API Docs

    Run npm run typedoc. This will create a '\docs' dir. click on the 'index.html' in this folder to see the docs.

    Breaking Changes

    API is almost identical to the original (breezejs 1.x) but small changes are noted below:

    • Breeze no longer depends upon Q.js. But it does depend on a ES6 promise implementation. i.e. the existence of a global Promise object. The setQ function is now a no-op.
    • The names of the enum values no longer have "Symbol" at the end. E.g. EntityStateSymbol is now EntityState.
    • The DataServiceOptions interface is now DataServiceConfig to be consistent with other naming
    • The initializeAdapterInstances method is removed; use the singular config.initializeAdapterInstance method.

    ### Adapter Changes The names of the adapter files have changed. E.g. breeze.dataService.webApi is now adapter-data-service-webapi, and the locations have changed due to Angular-compatible bundling.

    Also, the aggressive tree-shaking of tsickle/terser/webpack in Angular 8 removes the functions that the Breeze adapters use to register themselves! So you need to register them yourself.

    If you have this:

    import 'breeze-client/breeze.dataService.webApi';
    import 'breeze-client/breeze.modelLibrary.backingStore';
    import 'breeze-client/breeze.uriBuilder.odata';
    import { BreezeBridgeHttpClientModule } from 'breeze-bridge2-angular';

    Replace it with this:

    import { config } from 'cdt-breeze-client';
    import { DataServiceWebApiAdapter } from 'breeze-client/adapter-data-service-webapi';
    import { ModelLibraryBackingStoreAdapter } from 'breeze-client/adapter-model-library-backing-store';
    import { UriBuilderODataAdapter } from 'breeze-client/adapter-uri-builder-odata';
    import { AjaxHttpClientAdapter } from 'breeze-bridge2-angular';

    Note that now you do not import the BreezeBridgeHttpClientModule, just the AjaxHttpClientAdapter.

    Then, in your constructor function (for your module or Entity Manager Provider):

    constructor(http: HttpClient) {
        // the order is important
        config.registerAdapter('ajax', <any>function() { return new AjaxHttpClientAdapter(http); });
        config.initializeAdapterInstance('ajax', AjaxHttpClientAdapter.adapterName, true);

    The above has been tested on Angular 7 and 8, and should work for earlier versions.

    For apps that use global JavaScript libraries, the UMD versions are still available, under the bundles directory:

    <script src="node_modules/breeze-client/bundles/breeze-client.umd.js"></script>
    <script src="node_modules/breeze-client/bundles/breeze-client-adapter-model-library-backing-store.umd.js"></script>
    <script src="node_modules/breeze-client/bundles/breeze-client-adapter-data-service-webapi.umd.js"></script>
    <script src="node_modules/breeze-client/bundles/breeze-client-adapter-ajax-angularjs.umd.js"></script>

    Compile Notes

    In general we have avoided using null parameters in favor of undefined parameters thoughout the API. This means that signatures will look like

    a(p1: string, p2?: Entity)

    as opposed to

    a(p1: string, p2?: Entity | null);

    This IS deliberate. In general, with very few exceptions input parameters will rarely say 'p: x | null'. The only exceptions are where we need to be able to pass a null parameter followed by one or more non null params. This is very rare. SaveEntities(entities: Entity[] | null, ...) is one exception.

    Note that this is not a breaking change because the underlying code will always check for either a null or undefined. i.e. 'if (p2 == null) {' so this convention only affects typescript consumers of the api. Pure javascript users can still pass a null in ( if they want to)

    Note that it is still acceptable for api calls to return a null to indicate that nothing was found. i.e. like getEntityType().

    Jasmine tests

    1. from command line run 'npm install jasmine -g' ( global install). run 'jasmine' from top level breeze-next dir.

    2. from vs code debugger add this section to 'launch.json'

           "name": "Debug Jasime Tests",
           "type": "node",
           "request": "launch",
           "program": "${workspaceRoot}/node_modules/jasmine/bin/jasmine.js",
           "stopOnEntry": false,
           "args": [
           "cwd": "${workspaceRoot}",
           "sourceMaps": true,
           "outDir": "${workspaceRoot}/dist"

      run 'npm install jasmine' // local install
      set breakpoint and hit Ctrl-F5.
