        // The url pointing to API definition.
        URL:          "http://localhost:8080/swagger/doc.json",
        DeepLinking:  true,
        DocExpansion: "list",
        DomID:        "#swagger-ui",
        // The UI prefix URL (see route).
        Prefix:       "/swagger",
    }
    swaggerUI := swagger.Handler(swaggerFiles.Handler, config)

    // Register on http://localhost:8080/swagger
    app.Get("/swagger", swaggerUI)
    // And the wildcard one for index.html, *.js, *.css and e.t.c.
    app.Get("/swagger/{any:path}", swaggerUI)

    app.Listen(":8080")
}
  1. Run it, and navigate through http://localhost:8080/swagger/index.html, you should see the Swagger 2.0 API documentation page.

  2. If you want to disable swagger when some environment variable is set, use DisablingHandler instead of Handler.

swagger.DisablingHandler(swaggerFiles.Handler, "THE_OS_VARIABLE_NAME_HERE", config)
