iriswagui

This package allows the user to easily add a Swagger UI to an Iris application. It does so by embedding the Swagger UI assets and adding a party to a parent party that implements all the necessary endpoints.

Basic usage example:

package main

import (
	"flag"
	"log"

	"github.com/alchemy/iriswagui"
	"github.com/kataras/iris/v12"
)

func main() {
	specPath := flag.String("spec", "data/swagger.json", "specification file `path`")
	addr := flag.String("addr", "127.0.0.1:8888", "listening address `host:port`")

	app := iris.New()
	party := app.Party("/documentation")

	config := iriswagui.Config{
		SpecRefs: []iriswagui.SwaggerSpecRef{
			{Name: "MyAPI", URL: *specPath},
		},
	}
    // Swagger UI will be served from /documentation/swagger
	err := iriswagui.HandleSwaggerUI(party, "/swagger", config)
	if err != nil {
		log.Fatalln(err)
	}

	err = app.Listen(*addr)
	if err != nil {
		log.Fatalln(err)
	}
}

Swagger UI configuration

Swagger UI is highly customizable. This package Config struct offers only minimal configuration options.
For instance, it accepts only a list of specification files and wether to use deep linking or not.
If only one specification file is added, Swagger UI will be configured to use BasicLayout, otherwise StandaloneLayout will be used along with the SwaggerUIBundle.plugins.Topbar plugin.
However, a complete custom configration can be specified by using the ExternalConfigURL field of the Config struct. When this field is not empty the configuration object will be fetched from this URL, ignoring all other fields.
