ngzone

I want to perform some action after Bluetooth connection is done and vice versa. Handled scenarios for connection and added success and failure handler also, and changing a flag to True and False in those handler functions. I printed that value using console.log, it changes in a component file but does not reflect in HTML. I tried using ngZone , but it's not working. Success and failure handle code are as follows: BluetoothService import { Injectable } from "@angular/core"; import { BLE } from '@ionic-native/ble'; @Injectable() export class BlueToothService { constructor(private ble: BLE){ }

Summary I created an Angular 6 library, but I get an error when I try to use it outside of the project in which it was created. This looks like a lot of code, but it's mostly boilerplate generated by the CLI. Minimal Working Test Case I created a very basic library with the Angular 6 CLI. ng new mylib cd mylib ng generate library example ng build --prod example I can then add <lib-example></lib-example> to src/app/app.component.html , run ng serve , and see the example component works as expected. Next I edit projects/example/src/lib/example.component.ts to add an an *ng-if="true" to the <p>

How would I go ahead with running a jasmine test for the following component: @Component({ moduleId: module.id, selector: "testComp", template: "<div>{{value}}</div>", }) export class TestComp { public value: string = "This is me"; constructor(public zone: NgZone) { this.zone.run(() => console.log("zone is here")); } } The following fails with the Can't resolve all parameters for NgZone: describe("test", () => { let fixture; let component; beforeEach(async(() => { TestBed.configureTestingModule({ declarations: [TestComp], schemas: [NO_ERRORS_SCHEMA], providers: [NgZone] }).compileComponents; }
