Here is a method I am trying to use:
getFilters(): Observable<Filters[]> {
let filters: Observable<Filters[]> = [
{
property: "Value",
property2: "Value2"
},
{
property: "Value3",
property2: "Value4"
}
return filters;
}
Unfortunately, I encountered this error message:
The type '{Property: string, Property2: string} is not assignable to the type Observable.
In order to achieve the desired outcome, you must establish an Observable:
import { Observable, of } from "rxjs";
getFilters(): Observable<Filters[]> {
let filters: Filters[] = [
{
property: "Value",
property2: "Value2"
},
{
property: "Value3",
property2: "Value4"
}
];
return of(filters);
}
After including the following imports, I was able to make it function:
import { Subscription, from } from "rxjs";
Subsequently, executing
return from(data);
Here is a breakdown of how the observable functions:
fetchData(): Observable<Data> {
let data = [
{
item: "Value",
description: "Description1"
},
{
item: "Value2",
description: "Description2"
}
];
return Observable.from(data);
}
Utilize it in this manner:
// Display each data item
let subscription = this.fetchData().subscribe(
x => console.log('onNext: %s', x),
e => console.log('onError: %s', e),
() => console.log('onCompleted'));
// => onNext: {item: "Value", description: "Description1"}
// => onNext: {item: "Value2", description: "Description2"}
