Travis branch Codecov branch Go Report Card GoDoc

Usage

Start using it
  1. Add comments to your API source code, See Declarative Comments Format.
  2. Download Swag for Go by using:
$ go get -u github.com/swaggo/swag/cmd/swag
  1. Run the Swag in your Go project root folder which contains main.go file, Swag will parse comments and generate required files(docs folder and docs/doc.go).
$ swag init
  1. Download gin-swagger by using:
$ go get -u github.com/swaggo/gin-swagger
$ go get -u github.com/swaggo/files

And import following in your code:

import "github.com/swaggo/gin-swagger" // gin-swagger middleware
import "github.com/swaggo/files" // swagger embed files

Canonical example:
package main

import (
	"github.com/gin-gonic/gin"
	swaggerFiles "github.com/swaggo/files"
	"github.com/swaggo/gin-swagger"
	
	_ "github.com/swaggo/gin-swagger/example/basic/docs" // docs is generated by Swag CLI, you have to import it.
)

// @title Swagger Example API
// @version 1.0
// @description This is a sample server Petstore server.
// @termsOfService http://swagger.io/terms/

// @contact.name API Support
// @contact.url http://www.swagger.io/support
// @contact.email support@swagger.io

// @license.name Apache 2.0
// @license.url http://www.apache.org/licenses/LICENSE-2.0.html

// @host petstore.swagger.io
// @BasePath /v2
func main() {
	r := gin.New()

	url := ginSwagger.URL("http://localhost:8080/swagger/doc.json") // The url pointing to API definition
	r.GET("/swagger/*any", ginSwagger.WrapHandler(swaggerFiles.Handler, url))

	r.Run()
}
  1. Run it, and browser to http://localhost:8080/swagger/index.html, you can see Swagger 2.0 Api documents.

  1. If you want to disable swagger when some environment variable is set, use DisablingWrapHandler
Example with disabling:
package main

import (
	"github.com/gin-gonic/gin"
	swaggerFiles "github.com/swaggo/files"
	"github.com/swaggo/gin-swagger"
    
	_ "./docs" // docs is generated by Swag CLI, you have to import it.
)

// @title Swagger Example API
// @version 1.0
// @description This is a sample server Petstore server.
// @termsOfService http://swagger.io/terms/

// @contact.name API Support
// @contact.url http://www.swagger.io/support
// @contact.email support@swagger.io

// @license.name Apache 2.0
// @license.url http://www.apache.org/licenses/LICENSE-2.0.html

// @host petstore.swagger.io
// @BasePath /v2
func main() {
	r := gin.New()
    
    // use ginSwagger middleware to 
	r.GET("/swagger/*any", ginSwagger.DisablingWrapHandler(swaggerFiles.Handler, "NAME_OF_ENV_VARIABLE"))

	r.Run()
}

Then, if you set envioment variable NAME_OF_ENV_VARIABLE to anything, /swagger/*any will respond 404, just like when route unspecified.
