Go项目中需要main.go吗？

Question

Without a background in C and only "beginner" experience in Go I'm trying to work out whether main.go is actually required or is just a convention.

I'm looking to create a simple web API but could someone clarify this for me?

Answer 1

main.go as a file is not required.

However, a main package with a func main() is required for executables.

Your file name can be called whatever you want.

E.g

myawesomeapp.go

package main

func main() {
  fmt.Println("Hello World")
}

Running go run myawesomeapp.go will work as expected.
