mkdir if not exists using golang

Question

I am learning golang(beginner) and I have been searching on both google and stackoverflow but I could not find an answer so excuse me if already asked, but how can I mkdir if not exists in golang.

For example in node I would use fs-extra with the function ensureDirSync (if blocking is of no concern of course)

fs.ensureDir("./public"); 

Answer 1

Okay I figured it out thanks to this question/answer

import(     "os"     "path/filepath" )  newpath := filepath.Join(".", "public") err := os.MkdirAll(newpath, os.ModePerm) // TODO: handle error 

Relevant Go doc for MkdirAll:

MkdirAll creates a directory named path, along with any necessary parents, and returns nil, or else returns an error.

...

If path is already a directory, MkdirAll does nothing and returns nil.
