How to set gin mode to release mode?

Question

I need to set gin mode to release mode. How should I do it?

Now when I run my API there is a hint like this:

[GIN-debug] [WARNING] Running in "debug" mode. Switch to "release" mode in production.
 - using env:   export GIN_MODE=release
 - using code:  gin.SetMode(gin.ReleaseMode)

I tried gin.SetMode(gin.ReleaseMode) but it does not work. I initialize my router here:

gin.SetMode(gin.releaseMode)    
router := gin.Default()

You have to call SetMode method before you initialize the gin router. E.x:

gin.SetMode(gin.ReleaseMode)
router := gin.New()

Just set GIN_MODE=release to your environment config.

Env config? you meant the `.env` file – shamon shamsudeen May 06 '20 at 08:23
Not sure if that'll work. You can simply set env name in our console before starting the application or can pass in as single statement like `GIN_MODE=release go run main.go` – Kunal Kapadia May 07 '20 at 10:06

@iambatman you would have to use a library to load an env file. – user3875913 Oct 16 '20 at 10:36

Just add gin.SetMode(gin.ReleaseMode) in your main function.

I will try it with upper case R in "ReleaseMode". – Soroosh Oct 14 '17 at 13:56

The upper case R is fundamental! – Gwyneth Llewelyn Jun 10 '20 at 10:47

gin.SetMode(gin.ReleaseMode)

This works. Remember that you need to set this before creating the router in your init function/main. It does not seem to work otherwise i.e Your code would look something like this.

func init() {
    gin.SetMode(gin.ReleaseMode)
    r := NewRouter()
    err := r.Run("8080")
}

The init function is called for each source file after all the packages are imported and the variables are initialized. https://golang.org/doc/effective_go.html#init

It would seem you do this by calling the SetMode method from within your app. Probably in your main, or possibly in an init function.

Yes I do, I call it in main function. So where is the right place to call it? – Soroosh Oct 14 '17 at 13:55
