According to lot of online polls, Visual Studio Code is the most popular IDE among Go developers. You can start Go development immediately after installing Go extension for VSCode, but some tuning may make your life easier. First of all, you may want to format the source code and reorganize imports automatically on each file save or code paste. In order to do so, put the following JSON snippet in your settings....
In the very early adoption of Go by the open source community, lot of developers already suggested the lack of generics. However, some other claimed that simplicity of Go shouldn’t be compromised by generics. Few days ago, the never ending discussions pro and contra generics are finally over. The proposal is accepted and we can expect generics in Go 1.18 somewhere in spring of 2022. You may wonder why does it take that long, but this is not just about the compiler but also some parts of the standard library may need to be rewritten in order to replace the old code which could benefit from generics....
If you have just started learning Go or already developing in Go for quite some time, you may noticed that most of the Go packages are imported directly from their respective VCS repositories, but there are some packages imported from URL’s like golang.org/x/text or go.uber.org/zap . If you try to visit such URL’s, you may see different results like being redirected to documentation or just some dummy page. This is completely different from packages hosted on GitHub, for example github....
If you don’t know yet, there were major changes by Google in protobuf and gRPC implementation for Go. New version should be better in all means so you should switch as soon as possible, if you are already using these technologies. In this article I am going to focus on Linux variant, but the upgrade procedure should be quite similar on OSX or Windows. In order to use protobuf compiler or generator, if you wish, you had to install protoc compiler....
Do you develop or plan to develop a Kubernetes native application in Golang, controller or operator? Such application strongly depends on being inside Kubernetes and development outside of Kubernetes may be a real hassle. Usually you have to build an image over and over again and restart the pod (with imagePullPolicy set to Always). This is very boring and time consuming procedure. Two years ago I developed an image to auto-recompile and auto-restart Go application, named go-reflex , but it was intented to be used by docker-compose....
