rxjs6

I'm upgrading to angular7 with rxjs6: in mouseWheelEvent type I am getting "Property 'wheelDelta' does not exist on type 'WheelEvent'" . Do we have any alternative for wheelDelta ? mouseWheelFunc(event: MouseWheelEvent): void { // var event = window.event || event; // old IE support let delta = Math.max(-1, Math.min(1, (event.wheelDelta || -event.detail))); if ( delta > 0) { this.mouseWheelUp.emit(event); } else if ( delta < 0) { this.mouseWheelDown.emit(event); } // for IE event.returnValue = false; // for Chrome and Firefox if ( event.preventDefault) { event.preventDefault(); } } ERROR in

Previously I was using rxjs-5 and I was using observable.partition as follows: const [isTiming$, isNotTiming$] = this.store.select(state => state.tetris.isTiming) .partition(value => value); After upgrade angular to 8 rxjs got upgraded to rxjs-6 which started throwing following error: providers/timer.provider.ts(27,5): error TS2339: Property 'partition' does not exist on type 'Observable<boolean>'. when I checked in older rxjs implementation it was implemented as follows: import { Observable } from '../Observable'; import { partition as higherOrder } from '../operators/partition'; /** * Splits

Initially, I had a function that simply checked for the presence of a token and, if it was not present, sent the user to the login header. Now I need to implement the logic of refreshing a token when it expires with the help of a refreshing token. But I get an error 401. The refresh function does not have time to work and the work in the interceptor goes further to the error. How can I fix the code so that I can wait for the refresh to finish, get a new token and not redirect to the login page? TokenInterceptor import {HttpErrorResponse, HttpEvent, HttpHandler, HttpInterceptor, HttpRequest}

Can anyone help with the scenario where this._getReactions$.next() not working whenever this.http.get(...) gets an error. I want to keep observable alive to take the next input. private _getReactions$: Subject<any> = new Subject(); constructor() { this._getReactions$ .pipe( switchMap(() => { return this.http.get(...) // http request }), catchError(error => { console.log(error); return empty(); }) ) .subscribe(data => { console.log(data) //results handling }); } onClick() { this._getReactions$.next(); } If observable dies it calls it error handler and they are closed you can't send anything

Any suggestions, how this can be rewritten in more promise-chaining style?: this.apiService.sendPutRequest('/api/users/activate', usrObj).pipe( map(() => { return this.apiService.sendGetRequest('/api/users/' + this.currentUserId).pipe( map(data => { return this.setActiveUser(data).pipe( map(() => { return this.apiService.sendGetRequest('api/tasks/user/' + this.currentUserId).pipe( map(tasks => { return this.taskService.setCurrentUserTasks(tasks); }) ); }) ); }) ); }) ); You can use switchMap for handling observables and tap for side efects handling. And you need to subscribe because it's cold
