Just wrote something small with Go Language. Simple CRUD/webservice with MySQL using gorilla mux and sqlx, but it is almost plain golang in dockerized environment. If anything wrong about it, tell me. If you know polish language you can check also this link: http://www.consdata.pl/blog/12-pirewsze-kroki-z-golang ;)

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
