Few days ago Go 1.18beta1 was released and with it the first official generics support. I was embarrassed with standard Go’s HTTP handler functions for quite a while. If you are not familiar with Go, you probably wonder why, but if you are familiar, I believe you know. For example, implementing a RESTful API using idiomatic Go requires lot of code repetition in order to JSON decode request bodies and JSON encode response bodies....
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....
In these uncertain times and multiple months of remote work, at least we have some more time to dive into something new. I have been developing in Go since 2017, learned some TypeScript in the meantime, but few days ago I wanted to get into Rust once again. First time, approximately a year ago I gave up very quickly, realizing that Rust requires lot of time to learn and I didn’t have that much time at the moment....
