问题 I want to include the Telegram login widget in my Angular application. For this, you have to include the following script: <script async src="https://telegram.org/js/telegram-widget.js?5" data-telegram-login="bot_name" data-size="large" data-auth-url="https://myurl.example/api/telegram" data-request-access="write"></script> Embedding scripts in Angular templates is not allowed, it will just be removed. (However, it is possible to include a script tag via this hack.) Is there a non-hacky way

问题 I am looking to create a super generic API Resolver in my application. I want all "GET" requests, possibly extend it to other verbs in the future, to use this resolver. I want to be able to pass the URL and the verb of the request to the resolver and then handle making the function call from there. This resolver will be used on any Angular route definition with a param called "id" and I want to be able to specify the return type for this resolver. This is conceptually what I am looking to do,

问题 In an Angular app, I use HttpClient and RxJS operators to make some API calls. For example: return this.httpClient.put(url, JSON.stringify(treeOptions)) .pipe( map(this.extractTreeData), catchError(this.handleError) ); The extractTreeData method basically changes some properties returned by the API: private extractTreeData(res: any) { let apiTree = res.data; // The tree comes inside the 'data' field let newTree : any; try { let str = JSON.stringify(apiTree); str = str.replace(/"children"/g, '

问题 I've migrated a project from Node 6 to Node 10 and in the process made some changes and version upgrades which resulted in failing test cases and whatever fixes I tried, the test are still failing on "ReferenceError: Zone is not defined" I've tried changing the versions of different dependencies incrementally from basic to latest and still the tests would not pass. Here is the Package json: "scripts": { "ng": "ng", "start": "ng serve", "build": "ng build", "build:prod": "ng build --prod --env

问题 I migrated to PrimeNG 6.1.7 and I've a problem with p-dropdown. This is my code import in app.module (taken from a simple example): import { BrowserModule } from '@angular/platform-browser'; import { NgModule } from '@angular/core'; import { AppComponent } from './app.component'; import { BrowserAnimationsModule} from '@angular/platform-browser/animations'; import {DropdownModule} from 'primeng/dropdown'; // include this for dropdown support @NgModule({ declarations: [ AppComponent ], imports
