In my previous 2 blogs I have shown you how to build a HTTP/2 webserver. In these blogs we have covered self signed TLS certificates as well retrieving a Certificate via Letsencrypt. I mentioned there you will have to expose your server publicly on the internet. However I now figured out there is another way. So please continue reading. Let's Encrypt is a free, automated, and open certificate authority brought to you by the nonprofit Internet Security Research Group (ISRG). Letsencrypt imple…

Pretty often I see developers struggle with setting up a webserver running on https. Now some might argue, why to run a webserver on https during development? The reason for that is simple. If you would like to benefit from HTTP/2 features like server push, utilizing the http.Pusher interface, you will need to run your webserver on HTTP/2. That is the only way how you can very early on in the development process test this. In this blog I'm showing you how to do that in Go using Letsencrypt and…

In this blogpost I want to show you how you can easily get your React SPA app with clientside router work properly with your Nginx setup. I will also show you how to serve your React App over HTTP/2 and how you can leverage from http2 server pushes. To do so I will show you how to do that with the Nginx Docker image. When running your webapp using the development server you will in general not face any issues, however when running the static build on a production server you will most likely f…

In a previous blogpost I wrote how to create a Webserver in Go with graceful shutdown. This time I want to show you a more improved version which you can utilize better in your projects as it can be used as a drop in server.go file in your project where I also make use of some popular high performing libraries. In previous example I coded the full example in main.go. Although nothing wrong with that I learned while building microservices for a while it would be more convenient for me if I cou…

In this blogpost I want to show you how you can make a http webserver in Go with gracefull shutdown. Using this approach you allow the server to clean up some resources before it actually shuts down. Think about finishing a database transaction or some other long operation. We will be using the things we learned in my blogpost on concurency. So expect to see channels and go routines as part of the solution. When I create new http servers I usually start with an commandline flag to provide the…

In the last couple of years web applications technologies and frameworks went through a fast paced transformation and evolution. For all these evolutions there was coined a marketing term which (by coincidence) all end on …ive. So lets coin another one. In this article I'm going to explain you the basic concepts of all these principles which combined allow you to build an impressive web application. Responsive Web Design It started all back in (from top of my head) late 2010, with the idea o…
