Build a Go Webserver on HTTP/2 using Letsencrypt

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 a self-signed certificate when working offline. In my previous blog I have already shown you how to use self-signed certificates in Nginx to use HTTP/2 features. I have also written a blog a long time ago on how to get a Letsencrypt certificate for your Azure website.

Manage Go tools via Go modules

In this blog I will cover how I’m managing and versioning the tools my Go projects depend on. Go Modules are available since Go 1.11. Using Go Modules you can manage the dependencies for your project. You can compare it to NPM in Nodejs projects or Maven in Java project or Nuget in .NET projects.

Improved graceful shutdown webserver

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.

Go webserver with graceful shutdown

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.

Go interfaces and type assertions

In this blog I would like to zoom in on Interfaces and type assertions in Go. Compared to language like c# and Java implementing interfaces works slightly different. In the remainder of this blog I want to give you a bit of theory and practical usecases. In case this is your first time working with Go you might want to check out this blog which shows you how to setup your development environment including a small hello world.

Start on your first Golang project

A couple of months ago I started to do some coding in Go a.k.a Golang. Not only because they have an awesome logo ;-). My main reason was because I wanted to have something running as bare metal as possible on my Raspberry Pi and I wanted to have it available for different platforms to be easy to install. Some other reasons are the ease of creating async code by using Go in front of your methods and the unique approach of channels to sync between go routines (threads). I have been reading a lot about Go since it was released in 2012, now it was time to really get my hands dirty and try it for myself. Curious, continue reading…
