I am trying to wrap my head around observables. I love the way observables solve development and readability issues. As I read, benefits are immense.
Observables on HTTP and collections seem to be straight forward. How can I convert something like this to observable pattern.
This is from my service component, to provide authentication. I'd prefer this to work like other HTTP services in Angular2 - with support for data, error and completion handlers.
firebase.auth().createUserWithEmailAndPassword(email, password)
.then(function(firebaseUser) {
// do something to update your UI component
// pass user object to UI component
})
.catch(function(error) {
// Handle Errors here.
var errorCode = error.code;
var errorMessage = error.message;
// ...
});
Any help here would be much appreciated. The only alternative solution I had was to create EventEmitter
s. But I guess that's a terrible way to do things in services section
If you are using RxJS 6.0.0:
import { from } from 'rxjs';
const observable = from(promise);
