Don’t use Golang

Golang is a trend now but there is a lot of projects where you have to avoid of using it.

Let’s start from what kind of benefits brings Golang for your team/project:

– Easy to learn and get started with. This helps to grow your team quickly and involve new people even without any experience with Golang.

– Built-in concurrency and a robust standard library. Which allows to utilise your CPU in the most effective way and easily create multithreading applications (channels, mutex, atomic etc.).

– Strict types helps to avoid some basic coding issues. So these options shows us that Golang is a good tool for high performance projects and big growing teams.

But otherwise when your team is small and you don’t need to solve high performance tasks. That means that you will have some troubles like a very big codebase.

– Lack of generics in Golang will make you to write / support more code.

– Writing of multithreading programms even in Golang requires to have senior engineers. So that means you will have to spend more money on your team without any incomes from using Golang.

– It will take more time to release because you will need to write/support a bigger codebase.


When you don’t need to use Golang in your team/project?

– Your project is not simple (it is not quite small like some CLI utilities or small service) and it should be build as a monolithic application with a small team

– Your budget is not big and you don’t have too much time for release

– Your project is new and you have to release it ASAP to make money

– You don’t have any high performance problems which can not be solved on your current technical stack

TOP 5 of the most stupid questions about Golang for Interviews of Senior Engineers

  1. Slices vs Arrays – – I think some newbies in interviews think that it will show how deep the candidate understands internals of Golang type system. WAT? – Pls, don’t ask such questions just ask about cases.
  2. What is the String type in Golang? Is it mutable ? – no comments, I don’t even know what is the purpose of this question. LOL
  3. Why Golang needs Slices? – same as #2
  4. What programming language will you choose for development?
  5. Golang vs Node JS and why you prefer Golang instead of JS ?

Note №0 “Defeat your own fears on work”

Sometimes we have a task that causes a feeling of fear. This fear appears because the task has something new, something in what I am not experienced yet.

My list about how to solve this and defeat such fears:

  1. Relax and think why you have a fear
  2. Ask your supervisor/teammate for advice/support
  3. Find some examples of solutions for a similar task
  4. Prepare first version of solution and discuss it with somemone (superviser, client, teammate)
  5. Update your solution according to feedback from them and go back for review with your supervisor/teammate

    Steps 4-5 are repeatable unless you have a proper solution.

All of us made something in the first time and the fear is a normal for everyone.

Golang Application Template

Here is my template for Golang Application – https://github.com/ildarusmanov/gobase https://github.com/wajox/gobase

Only one thing that you have to do after git clone – replace all package name entries, from github.com/ildarusmanov/gobase github.com/wajox/gobase to [your_package_name]

UPD:

Template has been updated and moved into wajox/gobase repository.
