HTML5 comes with a lot of handy features which can really improve user experience of your web application significantly if you use them wisely. Caching cold data on the client, such as lookups can significantly save the amount of traffic, page load time and even you backed services load. One of the HTML5 features that can help you do this are sessionStorage and localStorage...read more

Logging is an essential part of the application. It gives you insights which allows you to see your application behavior or even user behaviour and actions taken by them in the application.Serilog is most probably the most popular library for logging in .NET Core applications...read more

Tagging Docker images is important to keep track of versions of the service running and to easily roll back in case of faulty behavior of the application. The version strategy which is the most clear and understandable is tagging image with version of the application for example ...read more

This is not a new subject and the support for handling WebApi input and output was introduced in .NET Core 2.0 and it's been there since then. There are couple of useful pages out there and it is even well documented on Microsoft official page Custom formatters in ASP.NET Core Web API...read more

With growing popularity of dotnet Core, Git and Docker, developers who used to work mainly on Windows are now getting used to CLI environment and obviously Linux. Windows is still a development environment platform of choice, bit since Microsoft already developed and published Visual Studio Code as a cross platform IDE for Windows, Linux and Mac. Although it is still not mature as Visual Studio 2017, it is a decent tool for .NET Core applications development...read more

In memory caching is not a bullet proof way of caching data in an application, especially if this application is distributed. The lack of synchronization between nodes can cause you application to misbehave showing wrong data or even throwing exceptions and crashing. This is one of the main reasons why distributed caching is the best way of doing the caching in your web application. But not all applications you might be developing need to run as distributed on multiple machines...read more

Recently I wanted to try to spin up a simple .NET Core application on my local cluster which I built in my previous article Manual setup of Kubernetes cluster on a Virtual Machine with kubeadm. The problem I had is that I needed to test applications in this cluster and deploy them as service in order to monitor potential issues behavior. As deployment of Kubernetes service needs an image to pull from, I decided to use dockerhub to push my test images, but they first needed to be created. ...read more

If you have a website like this one with articles and you would like to suggest most visited articles to your visitors, there are few ways to do this. One of them is definitely a custom solution that can track and store count of every visit per page you have, or without any re-inventing of wheel you can just hook to Google Analytics API to pull the data...read more

Few months back I wrote an article on how to create Linux daemon in .NET Core using generic host class introduced in 2.1 version of .NET Core. This code works just great on Linux OS when configured as a daemon in systemd and provides more less same concept you would have with Windows Service written in .NET Framework 4.x. The code works just fine on both Windows and Linux hosts, but because it is compiled as a Console Application, you do not really get to run it on your Windows machine as a Service...read more

Kubernetes is one of the most popular container orchestrator. It is platform agnostic and although it uses Docker as its default container engine it can also run on Rocket developed by Core OS team...read more

For my website, since it runs on Umbraco 6 and it is basically ASP.NET MVC application. To reduce load time and increase website performances I decided to alternate the response of the application and minify it using simple regular expression. Initially I was trying to do this with YUI Compressor library which has .NET port as NuGet YUICompressor.NET which works fine in most of the cases, but in my case does not skip PRE tags which I use for code snippets on the website...read more

Caching common data like lookups for example in memory of your app can increase significantly your MVC web application performances and response time. Of course this data has to be periodically refreshed. You can use various approaches to refresh data including expiry, but this can create potential bottle necks in your application since once data expires, you will use request thread to pull the data, cache and serve the request response back...read more

Pixel tracking, although it is the oldest method for tracking conversions in marketing, it is still used widely and some big companies like Facebook are still overing it as one of the methods for tracking the conversions of on your web pages. Tracking conversion via pixel method is still widely used because of it's simplicity. It does not require any complex client side implementation ant thee fore it ensures that it will execute on pretty much all the browsers that can load images...read more

Limiting the number concurrently running Tasks is not that often requirement in a code, but eventually you'll find yourself in the situation that for the most likely performance issues you'll have to limit number of concurrently running Tasks. One of these situations is when you have long running operations in the Task. If you spin up to many Tasks you will seriously degrade your application performance...read more
