Easy way to automatically unsubscribe from RxJS observables in Angular components

import { Subscription, Observable } from 'rxjs';

const HAS_DECORATOR = Symbol('__safeSubscribeDecorator');
const SUBSCRIPTION = Symbol('__safeSubscribeSubscription$');
function SafeSubscribe(destructorName = 'ngOnDestroy') {
    return (classType) => {
        const originalDestroy = classType.prototype[destructorName];
        classType.prototype[destructorName] = function () {
            originalDestroy && originalDestroy.call(this);
            this[SUBSCRIPTION]?.unsubscribe();
            this[SUBSCRIPTION] = null;
        };
        classType.prototype[HAS_DECORATOR] = true;
    };
}
function safeSubscribe(target, ...args) {
    const sub = this.subscribe(...args);
    if (target) {
        const hasDecorator = Object.getPrototypeOf(target)[HAS_DECORATOR];
        if (!hasDecorator) {
            throw new Error(`${target.constructor.name} class must be decorated with @SafeSubscribe() otherwise Observable<T>.safeSubscribe() will have no effect.`);
        }
        if (!target[SUBSCRIPTION]) {
            target[SUBSCRIPTION] = new Subscription();
        }
        target[SUBSCRIPTION].add(sub);
    }
    return sub;
}
Observable.prototype.safeSubscribe = safeSubscribe;
