Go (Golang) Naming Conventions: The Complete Reference

Go enforces naming conventions through its visibility rules: capitalized names are exported (public), lowercase are unexported (private).

Visibility by Case

func GetUser() {}  // Exported — accessible from other packages
func getUser() {}  // Unexported — package-private

Conventions

Element	Convention	Example
Package	lowercase, single word	http, fmt, json
Variable	camelCase	userName, maxRetries
Function (exported)	PascalCase	ParseJSON
Function (unexported)	camelCase	parseJSON
Interface	PascalCase + -er suffix	Reader, Writer, Stringer
Struct	PascalCase	HttpClient
Constant	camelCase or PascalCase	maxSize, StatusOK

Go-Specific Rules

• No SCREAMING_SNAKE_CASE for constants — Go uses camelCase/PascalCase
• Acronyms stay all-caps: HTTPClient, XMLParser, URL
• Getters don't use "Get" prefix: user.Name() not user.GetName()
• Package names should not repeat in exported names: http.Client not http.HttpClient
