Managing Complexity

"The Data Access layer should be in its own project", was one of the points that I came across during a discussion with another architect from my team. The reasoning was that if it is separate, it wouldn't impact the service using it. While on the surface the logic seems sound, do we ever stop and think, hmm do we really need to introduce this complexity? How many times do we see us switching from SQL Server to Mongo DB? Is the additional complexity and work really worth it?

Software Developers, especially those from object oriented language background (C#, Java, etc.) tend to love complexity. I too have been guilty of the same. But recently I came across a tweet which made me pause and take notice.

One should always follow SOLID principles while developing but also keep in mind the practicalities of the situation. Not all of us are developing the next Netflix, mostly we are just putting data over text boxes.

Managing complexity and your itch to create a truly flexible software is a balancing act. My advice would to keep it simple and match your needs not some lofty version of ideal software that you have in mind.

Integrating React with SonarQube using Azure DevOps Pipelines

In the world of automation, code quality is of paramount importance. SonarQube and Azure DevOps are two tools which solve this problem in a continuous and automated way. They play well for a majority of languages and frameworks. However, to make the integration work for React applications still remains a challenge. In this post we will explore how we can integrate a React application to SonarQube using Azure DevOps pipelines to continuously build and assess code quality. Creating the React Application Let's start at the beginning. We will use npx to create a Typescript based React app. Why Typescript? I find it easier to work and more maintainable owing to its strongly-typed behavior. You can very well follow this guide for jsx based applications too. We will use the fantastic Create-React-App (CRA) tool to create a React application called ' sonar-azuredevops-app '. > npx create-react-app sonar-azuredevops-app --template typescript Once the project creation is done, we

Centralized Configuration for .NET Core using Azure Cosmos DB and Narad

We are living in a micro services world. All these services are generally hosted in Docker container which are ephemeral. Moreover these service need to start themselves up, talk to each other, etc. All this needs configuration and there are many commercially available configuration providers like Spring Cloud Config Server, Consul etc. These are excellent tools which provide a lot more functionality than just storing configuration data. However all these have a weakness - they have a single point of failure - their storage mechanism be it a file system, database etc. There are ways to work around those but if you want a really simple place to store configuration values and at the same time make it highly available, with guaranteed global availability and millisecond reads, what can be a better tool than Azure Cosmos DB! So I set forth on this journey for ASP.NET Core projects to talk to Cosmos DB to retrieve their configuration data. For inspiration I looked at Steeltoe Con

Add Git Commit Hash and Build Number to a Static React Website using Azure DevOps

While working on a React based static website recently, there was a need to see exactly what was deployed in the Dev/Test environments to reduce confusion amongst teams. I wanted to show something like this: A quick look at the site's footer should show the Git Commit Hash and Build Number which was deployed and click through to actual commits and build results. Let's see how we achieved this using Azure DevOps. Git Commit Hash Azure DevOps exposes a variable called  $(Build.SourceVersion) which contains the hash of the commit. So I defined a variable in the Build Pipeline using it. Build Id and Build Number Azure DevOps also exposes two release time variables  $(Build.BuildId) and  $(Build.BuildNumber) which can be used to define custom variables in the pipeline. So we have a total of 3 variables defined: Next we use these variables in our React App. I created 3 global variables in index.html and assigned a token value to them. < script   type = "text/JavaScript&quo
