Angular_TourOfHeroes

Welcome to the Angular_TourOfHeroes wiki!

This is abaout the tutorial from angular.com As Web http connection we use go fiber. We will use go as Backend and angular with graph ql as Frontend to create a strong variable Development.

This package is created for costumers, which want a web based HMI in their company

Beckhoff could be a base with ads. You can visualize complex TwinCat enviroments with just changing your angular webpage.

You do not longer need a machine programmer, you can just hire a web developer to create your machine HMI

ads2web's Issues

Not possible to create hero without init

export class HeroDetailComponent implements OnInit {
@input() hero : Hero = { //Warum kann ich hier kein element erzeugen, ohne es zu initialisieren
id: 1,
name: 'Windfurz'
};

export class HeroDetailComponent implements OnInit {
@input() hero : Hero;

I would say the lower thing should work to

Error read Route

On branch in_appNavigation
FIle /src/app/hero-detail/hero-detail.component.ts Zeile 22
Property get does not exist
Ich bekomme es nicht hin die ID aus der Route auszulesen. Ich bekomme immer compiler Fehler

go http

Its not possible to send two different http serves.
/foo works

but together just the first one in log. is working

Array access for Hero Element

On branch in_appNavigation
FIle /src/app/hero.services.ts Zeile 22
Ich bekomme über find keinen Zugriff auf das Array Element Hero.
Mit einem return eines statischen Hero HEROES[1] funktioniert es.

Go return Hero Array

c.fiber could not return Hero[]
so i tried it with return c.JASON[a]
That just return the struct but not the data in the Hero[]

Hero service takes 2 s

In app/heroes/heroes.components.ts
the getHeroes() need in line 20 time to get the Heroes. But the code is still running and go on with undefined. Later ther HeroService send the Heroes and you can see the arry on the webbrowser, but the console printing the erroes.
We need to wait until the getHeroes() is finished
