In the last few months, my Twitter feed has been dominated by one topic, tRPC. tRPC is a library that provides type-safety between your front end and backend, in theory, it allows you to quickly build applications. In today’s post, I would like to explore tRPC, its capabilities and features, and how it could be used in a project. To get started, I will create a new Node.js app using Express. If you prefer to use React or Next.js see the official docs. ...
I enjoy writing unit tests and any tools that make writing tests easier are appreciated. For the last year, I have incorporated AutoFixture into all of my unit tests. I have found AutoFixture to be an excellent tool, it changed the way I approach the “Arrange” phase. Previously, my arrange phase involved manually assigning values to properties, in a small class that is referenced by a few tests, you may tolerate manually assigning values. Once you start to deal with a class that has many properties such as nested properties as shown on the “Employee” class below, things get out of hand. ...
In my last post, Kubernetes In WSL - Connect to a service from Windows, I explored a few ways to connect to a Kubernetes service from the host machine, Windows. In the end of that blog post, I stated that using HostPort was the best option because at the time I did not know how to assign a static IP address to WSL. Without using a static IP address, when WSL is restarted a new IP is assigned. Having a dynamic IP made it harder for me to connect to a Kubernetes service from Windows as I would need to update all my configurations whenever a new IP was assigned to WSL. ...
Today’s post is a follow-up to my Use Kubernetes In WSL blog post, where I outlined how to install Kubernetes on WSL. As noted at the end of the post, I was having issues connecting from the host, a windows machine, to Kubernetes in WSL. Connection Issue The main issue I was facing was that I could not connect to a pod running on Kubernetes using window’s localhost. Take the following Nginx deployment obtained from the official Kubernetes documentation. ...
If you are a fan of the strategy pattern, and you find yourself adding a lot of conditional logic around each strategy then you should consider replacing all branching logic using inversion of control. Take the following code as an example. It defines a strategy for reading different file types. For simplicity, the code writes out to the console a message, in a real-world application, the logic would be far more complex, but we are not interested in that logic, rather we are interested in how the strategy pattern works and how we can improve its usage. ...
A while back I made a blog post titled, Tools For The Modern Day Developer, in which I listed the tools I thought at the time every developer should be using. Today, I still stand by that list, but I would like to add an additional tool that lately has become super useful to me, that tool is Mockoon. Mockoon is a free and open-source mock API tool created by Guillaume in 2017. It offers Docker support, a CLI, importing and exporting of Mockoon environments, it works with OpenAPI 3.0 files. In many ways it feel like Postman, even the UI feels like the old classic Postman UI. ...
There have been a few instances where I could not figure out a problem within WSL. Problems that would be easier to fix if I had a UI instead of just an instance of the WSL shell. If you find yourself in such a situation know that you can install the UI portion, a Linux desktop on top of WSL. Once the UI has been installed you can RDP into the WSL instance allowing you to use the WSL distro as if it were natively installed on your machine. ...
If you are writing unit tests in .NET, you may eventually find the need to generate code coverage reports to show how much coverage your project has. The best tool for code coverage reports in my experience has been coverlet because it supports both .NET Framework and .NET Core. NUnit NUnit, the tried and tested framework originally being a port of JUnit. A powerful tool that when combined with coverlet console can be used to generate code coverage reports. To demonstrate, I will create an NUnit test project targeting .NET Framework 4.8 along with a Class Library type project also targeting .NET Framework 4.8 ...
If you find yourself in need of having to use Kubernetes in WSL, know that it is possible, hard, but possible. It might require upgrading your machine to Windows 11 if you are on Windows 10 and a few other packages. Prerequisite To get started we need to know what version of Windows you are on. This is important because Kubernetes will be installed using Microk8s, which requires having snap installed and working. Snap won’t work in older Windows builds. ...
A few months ago I was looking for a new HTTP client to use within my applications. I first checked on awesome dotnet under the HTTP section to see what projects the .NET community is using instead of the default HTTP client. One that immediately stands out is RestSharp, this project has been around for a while and is overall a good choice, but I was looking for something new and fresh, that is when I came across Flurl. ...
