A couple of days ago Facebook released Yarn, a new package manager for Javascript, with a focus on speed and consistent package dependency management across machines. With Yarn, engineers still have access to the npm registry, so I thought it worth the try to test the claimed speed improvements between package installation using yarn and npm default installation process. For my tests I used ng-lightning, a project for…
In this post we are going to explore what we need in order to setup a local environment for our Azure Functions implementation, and how we can easily update our Azure Functions App through GitHub, using continuous integrations. Let’s start with some details about Azure Functions. What is Azure Functions? Azure Functions is a serverless event-driven experience that extends the existing Azure App Service platform; serverless…
In this post we are going to explore a feature provided by Azure App Service called “Testing in production” that allows you to direct a portion of live user traffic to one or more deployment slots of your web app before swapping this deployment slot to production. You can, thus, analyze your app, check for exceptions or errors, and make certain everything works properly, before your app…
In this post we are going to explore: how to simulate CPU-load hosted on an Azure web app; how you can set simple rules for automatic scaling; and how to setup alerts to get notified when your app is under pressure. Let’s start by creating a very simple ASP.NET core web api application. The default web api template in Visual Studio is more than OK….
Sometimes, it is helpful to be able to set a timer to auto shutdown your PC, after a certain amount of time. In Windows 10 you can do that through many ways, but essentially, using the same command. Command Prompt Type shutdown -s -t 300 where 300 is the amount of seconds to wait till the shutdown start (around 5 minutes) Powershell The…
A common practice to increase the performance and availability of a web application is to distribute it in multiple servers across the globe. Thus, customers will be served from the data-center that is closer to them, thus reducing response latency. In addition, when one server confronts downtime, other servers will handle the requests without the user noticing it. In this post we will explore how easy it is to setup…
In order to use .NET Core on your Mac, you first need to install the latest version of OpenSSL. The easiest way to get this is from Homebrew.

After installing brew, you need to do the following:
1 2 3 4 | ~$ brew update ~$ brew install openssl ~$ ln -s /usr/local/opt/openssl/lib/libcrypto.1.0.0.dylib /usr/local/lib/ ~$ ln -s /usr/local/opt/openssl/lib/libssl.1.0.0.dylib /usr/local/lib/ |
When trying to initialize a basic .NET project through dotnet new or restoring packages on an existing one, using dotnet restore, you might come across…
In this post we are going to use Visual Studio Team Services to automate the build and deployment task of an ASP.NET Core Web application to Azure. What is Visual Studio Team Services? Visual Studio Team Services (VSTS) provide a fast and easy way to plan, build and ship software across a variety of platforms. Whether you work in the cloud, on-premises,…
In this tutorial we are going to map a network drive on our computer to a file storage in the cloud using Azure File Storage. This can be very helpful if you want to share files among multiple computers and, bearing in mind that the storage is in the cloud, you can scale your drive as much as you need. First of all, let’s start with…
Sometimes you may need to render a certain view as string, for example when you want to send an email where usually the body is pure html. To do so, you need to create a service that takes two arguments: the first one is a string representing the path to the view you want to render; the second one is an object that is used from…
