Hosting dotnet core on Heroku

I've been getting back into building scrappy little web apps for my friends. On top of this, I recently joined a startup and getting away from Enterprise class software has made me make a huge mind-shift. In the recent past when I wanted to build apps I was thinking Kubernetes, Helm Charts, etc. However, in small app, and startup land reducing the barriers to ship is very important.

Exploring the dotnet cli

Now that dotnet core tools have been released I thought it would be good to look into the dotnet cli. This is a new command line interface to build, manage, compile and run dotnet core based applications

StatsN a modern statsd client for dotnet core, and dotnet 4.5

tl;dr click here

When we talk about capturing metrics in applications. One server/service that constantly is in all conversations monitoring, is statsd. Incase you have never heard of it, statsd is a udp/tcp server that you send your in-code metrics to. These metrics get aggregated by statsd, and are forwarded to various backends. Some backends are services like librato or sumologic. Other times you are sending metrics to time series databases such as graphite or god forbid influxdb.

This boils down to in code you can say "log whenever this block of code is hit" or say "measure how long this function takes to execute". These stories come together to form pretty graphs, and rich alerts. All of this enabled by statsd.

How the ASP.NET team made the web framework I have always wanted

So I know I do a lot of blogging about C#, or JavaScript, but I actually do a lot of nodejs apps as well as other languages. For a very long time I have not found the stack of my dreams. .NET has always been very close but there were multiple things about the app model that I was not a fan of. I think NancyFX has been the closest framework to my dreams in .NET land.

Wiring up client side logs into c#/node.js logging frameworks

Around a year ago I joined a new team where I work, and this team was starting to undertake a full rewrite of their code. We were going from a full c#/mvc app to a tiny c# api, and a very big SPA.

Early one one of the huge things to do was to make sure that our JavaScript error logs could land in our Log4Net infrastructure. I started to write something to do just that, and as I was coding I quickly realized this was less trivial that it sounded. We had something internal we could use, but it was tied to a lot of other code that we didn't want to pull in.

I started Bingling around and I stumbled across jsnlog. JSN log lets you quickly wire up your client side logs to your server. I have been able to get PR's into the code base and the guy behind it has been very friendly to me when I have had questions.

Moving from beta 7 to beta 8 in ASP.NET 5 (MVC 6)

So Beta 8 was recently announced, and I thought I'd update DotNetMashups to beta 8.

In case you havn't been paying attention, recently it was announced that helios was no longer a thing. Helios was the loader for ASP.NET 5 in IIS. Instead they are using the http Platform Handler to proxy the connections to kestrel.

So I thought that this was going to be a difficult update. I loaded the announcements repo in my browser and got to work. You can view the Pull request here.

Avoid the Godclass

I joined a team earlier this year, who own a core set of pages on our website. This part of the site makes us buckets of money, and was written by people whom are clearly smarter than me. However every platform is not without its quirks.

Most of the code is C# MVC but a lot of the problems with the platform are more historic architecture, and less .NET specific.

Razor Websites, lightweight C# web coding

I was exploring around github, and I stumbled upon an interesting project called Miniblog which was a lightweight blog engine written in c#. The thing that immediately stood out to me was the lack of a .csproj file.

As I dug around the code I realized this was not a Web App, which most of us were familiar with, but a websites project. I then suddenly realized that the whole thing only used razor!

I am a huge fan of Nancyfx because its much more lightweight than the MVC framework created at Microsoft. To say the least I am a massive fan of small tools, and micro frameworks. So when I realized this whole thing was powered by razor only I was immediately impressed.

I decided to dig around on the internet to see if anyone else was talking about this. I found out quickly that it has been possible for some time, but I didn't find many references about it.

The one thing that bummed me out about the Miniblog example was that it was not a web app. You can use nuget packages will websites, but you cannot make references to other projects in the solution. This was a problem for me, and unlike websites, web app's are precompiled which reduces application startup time.

Navigating the JavaScript waters in 2015

In this last year I have done much more JavaScript development than I have before. The landscape, and tools have exploded over the last few years. Gone are the days of JQuery widgets, and come forth have advanced virtual dom libraries, JavaScript servers, and multiple package managers. Along with new language features.
