What about removing line 11 and use the following instead?

{{#featureCORS}}
	"github.com/gorilla/handlers"
{{/featureCORS}}

(which will avoid blank lines)

"github.com/gorilla/mux"
)

Same suggestion as above:

			{{#featureCORS}}
			handler = handlers.CORS()(handler)
			{{/featureCORS}}
