go-swagger-ui

go-swagger-ui provides a simple way to serve Swagger UI in your Go web application. It embeds Swagger UI and provides a customizable http.Handler to serve it.

Features

• Provides a customizable HTTP Handler to serve Swagger UI.
• Supports many of Swagger UI's configuration options.
• Supports dynamic UI configuration in your Go application.
• Provides a CLI application to open OpenAPI specification files in a Swagger UI instance (browser window).

Installation

To install the go-swagger-ui package, use the following command:

go get github.com/alexliesenfeld/go-swagger-ui

Usage

package main

import (
	"fmt"
	swaggerui "github.com/alexliesenfeld/go-swagger-ui"
	"log"
	"net/http"
)

func main() {
	http.HandleFunc("/", swaggerui.NewHandler(
		swaggerui.WithHTMLTitle("My Example Petstore API"),
		swaggerui.WithSpecURL("https://petstore.swagger.io/v2/swagger.json"),
		swaggerui.WithTryItOutEnabled(true),
		swaggerui.WithPersistAuthorization(true),
	))

	fmt.Println("Starting server at port 8080")
	if err := http.ListenAndServe(":8080", nil); err != nil {
		log.Fatal(err)
	}
}

CLI Usage

Install the CLI application:

go install github.com/alexliesenfeld/go-swagger-ui/cmd/swui@latest

You can then use the CLI tool to serve OpenAPI spec files in a separate Swagger UI instance in a browser window.

swui /path/to/openapi-spec.yaml

swui also allows you to reload the browser window to see changes made to the spec file.

Roadmap

• Embed Swagger UI
• Provide simple but powerful http.Handler that is compatible with major web libraries
• Allow to change the majority of configuration parameters from within a Go application
• Make it possible to configure multiple spec file urls
• Provide a CLI tool to view OpenAPI spec files locally in a browser
• Add OAuth2 configuration possibilities (https://github.com/swagger-api/swagger-ui/blob/master/docs/usage/oauth2.md)
• Make plugins configurable
• Make presets configurable
• Allow using CDN instead of embedding Swagger UI
