Hello Brad,
Thanks for your add.
You are right : speaking is something, acting is an other thing.
So go to oceanvirtuel.eu (Angular 7 + Node + Mongo, NOAA, ...), and judge
the complexity by regestering to the next regatta.
You will then tell me about complexity of web apps.
Do not postulate
Greetings,
Reading this post, and your other one regarding observables makes wonder
the point you wish to make.
Certainly most angular 2+ applications do not need redux, nor a 'store' of
any kind. This AiA podcast with Wes Grimes makes that rather clear
Thank you Herve,
I'm new to angular so i'm leaning something everyday :D. Just one question
though. Since the "customer" variable may not be set when the view is
rendered so the {{}} is the mechanism that angular is asynchonously watch
the var and render when the value is available? If it is
Hello Arnaud,
I am not saying that your way of doing things does not work, I am sure that
it works. I am also sure that, because you master it now, you code it fast,
so you feel good with it.
I just say that you spent certainly more time to implement your way, than
using the way that I
Hi

Hi Hervé,
With the observables I find it very easy to use the async pipe: you don't
have to subscribe, store the result, keep the subscription and unsubscribe
when the component is destroyed.
I may have missed something but I use this extensively and I have not
noticed any drawback yet.
Hello,
Many discussions here a related to the use of async data in Angular, so let
me recall the basics.
Angular is natively designed to handle the async processes, because nearly
everthing is async in javascript (loading, events, ...). To intend so
Angular simply use the elvis operator
Hello,
Redux is useless in Angular, worth, it can be harmfull, by causing a lot of
useless complexity that will be handicapping.
Redux is made to store the states of the variables of your application, but
Angular is two-way data binding, so the states of the variables are watched
natively.
Oupps, the declaration of customer in the typescript of the component is of
course useless, I forgot to delete it from an older version.

Here is the complete solution.
1) Angular store as a service
import { Injectable } from '@angular/core';
@Injectable({
providedIn: 'root'
})
export class StoreService {
customer: any;
constructor() { }
}
2) Api service to get the data and store it inside the store (a timeout is
used

Now, if you use an *angular service* as a store, the async process is the
same, you will just feed
store.customer
instead of only
customer
locally in your component.
And in your template you will use
{{store.customer?.name}}
directly, so a change of this will be instantly and natively
Here is your component, with a timeout to simulate an async process to get
some user data :
import { Component, OnInit } from '@angular/core';
@Component({
selector: 'app-mycomponent',
templateUrl: './mycomponent.component.html',
styleUrls: ['./mycomponent.component.css']
})
export class
Here is your component, with a timeout to setup the customer in order to

templateUrl: './mycomponent.component.html',
styleUrls: ['./mycomponent.component.css']
