Go Language – First Impressions

Just wrote something small with Go Language. Simple CRUD/webservice with MySQL using gorilla mux and sqlx, but it is almost plain golang. If anything wrong about it, tell me 😉

Here are my impressions about it:

  • it feels pragmatic from the beginning
  • probably you don’t need any frameworks at all to use it
  • simpler = better, simplicity as a feature
  • quite easy to write REST application
  • the build in package manager ‘go get’ is cool thing
  • compilation & running time of go server is much faster than java
  • it doesn’t eat much of resources
  • you can use many text editors or IDEs for it (IntelliJ has Go Plugin)
  • gofmt – one and the only code formatter
  • designed for special needs, not for everything
  • it is easy to find examples by googling it, good enough community
  • return multiple values from Go functions – nice feature
  • syntax not beautiful like Python but still good
  • the build in ‘testing’ package – ok, but too simple (testify looks better)
  • concurrency – believe that it is nice, but didn’t tried it yet
  • it is much different than Scala – complexity vs simplicity
  • I think that I could be very productive with Go if i will get used to it
  • Docker, Kubernetes, CoreOs,  Consul, Flynn, Lime, Google, Dropbox…
  • heard that golang is good for ‘real time apps’ – want to try it soon
  • it seems to be good for building command-line tools
  • it is different than Java, little bit tricky at beginning, but easy to start 😉
  • ‘good when you need to write something yourself instead of using library’
  • need to find idea for real project, because I kinda like Go
