Monitor hapi based web service with Application Insights

Application Insights is a great tool which allows developers to get better understanding of what’s going on insight their applications and services. It’s platform-agnostic and can be used from pretty much everywhere: from ASP.NET and node.js on the server to client-only applications running in the browser. The documentation is quite good and will help you get started, but there is one thing that I found missing. There is a page describing how to interface Application Insights into node.js application, but it’s using node HTTP server in all the examples. While it might work for some, it doesn’t work for me. The app I’m currently working on uses hapi. In this post I’ll show how in just few lines of code you can instrument hapi-based application and get data flowing into Application Insights.

Moving datetimeformat.info to Azure Functions and GitHub Pages

I created datetimeformat.info couple years ago when I got tired of googling what the right custom format string for DateTime.ToString() method is. It used to be a simple ASP.NET site and I hosted it as an Azure Web App. The problem is, hosting it on Azure wasn’t cheap. datetimeformat.info does not get much traffic, there is minimal amount of logic there but because I hosted it on a single B1 Basic instance I used to spend ~$55 a month. Sure, I can pack multiple other websites and applications on the same instance and that money is something I get as part of my MSDN subscription anyway, but still, it felt wrong. That’s why today I updated it to use GitHub pages to serve static content and Azure Functions to provide required API. New cost of running the site: $0 (yes, zero!).

Programmatically creating a Pull Request against Visual Studio Team Services

There are certain scenarios, especially when developing software in environment which uses multiple repositories, where certain changes in a single git repository should be followed by another set of changes in another repository or repositories. Automating these tasks can make Continuous Integration pipeline and entire development system more efficient and let developers focus on writing code instead of manually dealing with multi-repository orchestration. Let’s see how that can be done using custom build scripts in Visual Studio Team Services.

Adding Matt operator to Roslyn - Binder

Following on my previous post where I showed how to add a new operator to C# and Roslyn today I’m going to describe how to make further progress on implementing matt operator: [email protected]. I already extender the Lexer and Parser to understand that new language construct. The next step is to make Binder aware of our new operator, to make sure it can only be used in the right places and with the right types. We also need to teach the compiler that <int> [email protected] <int> returns an int.
