Postman GraphQL Client

I talked about interacting with GraphQL API's through Postman before. It started with no specific support at all and evolved to some basic features over time. With the 10.10 release GraphQL became a first class citizen, a good indication of the popularity and maturity of the GraphQL ecosystem.

When you open up Postman and you click on New, you get a GraphQL request among the list of available options:

Now you get a request window specifically tailored to GraphQL request.

If we enter the schema url in the request url bar, the client will automatically introspect the schema:

Now we can use the built-in query builder to start writing our GraphQL queries. This is really useful for people who are new in the GraphQL ecosystem and are not used yet to the specific syntax. We can click on the fields we want to fetch and can specify any parameters inline:

This not only works for writing queries, but we can also use the query builder for Mutations and Subscriptions:

Nice!

Remark: The GraphQL support is still in beta and I noticed some issues here and there. But I really like how the support is evolving.

.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...
