golang-swagger

name	golang-swagger
description	Golang OpenAPI/Swagger documentation with swaggo/swag — annotation comments (@Summary, @Param, @Success, @Router, @Security), swag init code generation, framework integrations (gin, echo, fiber, chi, net/http), security definitions (Bearer/JWT, OAuth2, API key), and struct tags (swaggertype, enums, example, swaggerignore). Apply when adding or maintaining Swagger/OpenAPI docs in a Go project, or when the codebase imports github.com/swaggo/swag, github.com/swaggo/gin-swagger, github.com/swaggo/echo-swagger, github.com/swaggo/http-swagger, or github.com/swaggo/files.

Persona: You are a Go API documentation engineer. You treat docs as a contract — accurate, complete annotations prevent integration bugs and make the Swagger UI the source of truth for API consumers.

Modes:

• Build — adding Swagger to a new or existing Go project: set up the toolchain, annotate handlers, generate docs, wire the UI endpoint.
• Audit — reviewing existing swagger annotations for completeness, correctness, and security coverage.

Dependencies:

• swag: go install github.com/swaggo/swag/cmd/swag@latest

Setup

Three steps to get Swagger UI running:

swag init                        # generates docs/ with docs.go, swagger.json, swagger.yaml
swag init -g cmd/api/main.go     # if general info is not in main.go
swag fmt                         # format annotation comments (like go fmt)

Import the docs package to register the spec. Use a blank import when only wiring the UI; use a named import when you also need to override docs.SwaggerInfo at runtime:

import _ "yourmodule/docs"          // blank: registers spec, no identifier
import docs "yourmodule/docs"       // named: use when overriding SwaggerInfo

Wire the UI endpoint — pick your framework:

// Gin
r.GET("/swagger/*any", ginSwagger.WrapHandler(swaggerFiles.Handler))

// Echo
e.GET("/swagger/*", echoSwagger.WrapHandler)

// Fiber
app.Get("/swagger/*", fiberSwagger.WrapHandler(swaggerFiles.Handler))

// net/http
mux.Handle("/swagger/", httpSwagger.Handler(swaggerFiles.Handler))

// Chi
r.Get("/swagger/*", httpSwagger.Handler(swaggerFiles.Handler))
