Upgrading Angular 2 from beta 17 to RC4–Lessons learned Part 2

This is a continuation of a previous blog post found here: http://bartwullems.blogspot.be/2016/08/upgrading-angular-2-from-beta-17-to.html

New router

We’re almost there. With the upgrade from beta to RC the Angular team throw away their first Angular 2 router implementation and build a new one. Let’s fix our code to use the updated router…

In my original code I had the following:

I updated it to the following:

Next, I extracted the router config to a seperate file and created a provider to load it inside the Angular bootstrap logic:

The code to get router data changes as well:

The information from the current route is accessible through the ActivatedRoute object. This is an observable and inside your component you can subscribe for changes. However in this sample I used the snapshot property which captures only the state on the moment we navigated to the component(which is sufficient for this example).

More information about the “new new” router can be found in the documentation: https://angular.io/docs/ts/latest/guide/router.html

.NET 8–Keyed/Named Services

A feature that a lot of IoC container libraries support but that was missing in the default DI container provided by Microsoft is the support for Keyed or Named Services. This feature allows you to register the same type multiple times using different names, allowing you to resolve a specific instance based on the circumstances. Although there is some controversy if supporting this feature is a good idea or not, it certainly can be handy. To support this feature a new interface IKeyedServiceProvider got introduced in .NET 8 providing 2 new methods on our ServiceProvider instance: object? GetKeyedService(Type serviceType, object? serviceKey); object GetRequiredKeyedService(Type serviceType, object? serviceKey); To use it, we need to register our service using one of the new extension methods: Resolving the service can be done either through the FromKeyedServices attribute: or by injecting the IKeyedServiceProvider interface and calling the GetRequiredKeyedServic...

Kubernetes–Limit your environmental impact

Reducing the carbon footprint and CO2 emission of our (cloud) workloads, is a responsibility of all of us. If you are running a Kubernetes cluster, have a look at Kube-Green . kube-green is a simple Kubernetes operator that automatically shuts down (some of) your pods when you don't need them. A single pod produces about 11 Kg CO2eq per year( here the calculation). Reason enough to give it a try! Installing kube-green in your cluster The easiest way to install the operator in your cluster is through kubectl. We first need to install a cert-manager: kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.14.5/cert-manager.yaml Remark: Wait a minute before you continue as it can take some time before the cert-manager is up & running inside your cluster. Now we can install the kube-green operator: kubectl apply -f https://github.com/kube-green/kube-green/releases/latest/download/kube-green.yaml Now in the namespace where we want t...
