Intro to Core

In this package you'll find two categories of things:
Observables (regular and specialised ones)
operators (functions that'll wrap the observable into an observable with additional mechanics)
What is an Observable?
Install
npm i @hullo/core
...then in your code:
import { Observable, map } from '@hullo/core'
​
new Observable(observer => {
  observer.next(1)
    .then(() => observer.next(2))
    .then(() => observer.next(3));
    .then(() => observer.complete());
}).pipe(map(n => n * 2)).subscribe({
  next: v => { console.log(v) }
});
​
// logs out 2,4 and 6
