fiber-swagger

fiber middleware to automatically generate RESTful API documentation with Swagger 2.0.

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

3. 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

4. Download fiber-swagger by using:

$ go get -u github.com/arsmn/fiber-swagger/v2

And import following in your code:

import "github.com/arsmn/fiber-swagger/v2" // fiber-swagger middleware

Canonical example:

package main

import (
	swagger "github.com/arsmn/fiber-swagger/v2"
	"github.com/gofiber/fiber/v2"

	// docs are generated by Swag CLI, you have to import them.
	// replace with your own docs folder, usually "github.com/username/reponame/docs"
	_ "github.com/arsmn/fiber-swagger/v2/example/docs"
)

	app.Get("/swagger/*", swagger.HandlerDefault) // default

	app.Get("/swagger/*", swagger.New(swagger.Config{ // custom
		URL: "http://example.com/doc.json",
		DeepLinking: false,
		// Expand ("list") or Collapse ("none") tag groups by default

		},

		OAuth2RedirectUrl: "http://localhost:8080/swagger/oauth2-redirect.html",
	}))

	app.Listen(":8080")
}

5. Run it, and browser to http://localhost:8080/swagger, you can see Swagger 2.0 Api documents.
