Variables reliant on other variables within numerous Angular HTTP requests

A situation involves an Angular function with two HTTP GET requests, A and B. Request A returns data X while request B returns data Y, both of which are continuously changing in the backend. The goal is to display the real-time average of (X+Y)/2 using this function. How would you approach this scenario?

Answer №1

To achieve the desired outcome, utilize the rxjs zip operator which triggers an array of values when both calls emit their own respective values.

import { zip } from 'rxjs';
import { take, map } from 'rxjs/operators';

zip(call1, call2).pipe(
 take(1),
 map((dataArray) => { // calculate the average of the two values in your dataArray }
).subscribe(console.log)
