I have used Golang to develop business codes for a while. In this paper, I will sort out my experience and summarize common class libraries for easy reference. As I am a heavy Java user, I can not help but compare and ridicule, please forgive me.

Go do business development?

Here’s what it’s like to do business development with GO:

• advantages

  • Cloud native preferred, save within the province
  • Great for scripting, an alternative to Python

• disadvantages

  • If you don’t use it well, there will be panic. Direct process exit of online service is quite serious
  • Go does not have a SNAPSHOT version of Maven. It is based on the commit hash and date as the pseudo version. Invalid version is very easy to appear
  • Writing object-oriented is a bit of a chore, with a receiver for each method, unlike Java
  • The support of IOC is not as good as Java’s ioc standard and ecology. For example, Uber/DIG cannot inject map structure by name
  • Godoc is too crude and not as neat as Javadoc
  • There are no annotations or generics (it’s supported in the new version, but can’t be used properly until the surrounding ecosystem supports it), and the language is much weaker
  • As for coroutines, business development doesn’t seem to help
  • The package mechanism is very strange, the default is the last one, it is easy to conflict, not easy to identify, if the alias is added, it is a disaster, very bad analysis
  • Lack of a useful Test suite, unlike Java’s Juint, where you can just write a few annotations, which can be quite taxing

conclusion

The cost of business development with GO is quite high, which is definitely not saved within the province. If it is a big company, it can spend money on it, I have no words. Small and medium-sized companies, if their team is not go background, want to start from zero, feel the cost is quite large, personal opinion.
