Goatkeeper

GoatKeeper is an HTTP middleware for Golang that validates HTTP requests and their responses according to types defined in OpenAPI Specification.

Goals

• Single source of truth for APIs using OpenAPI specifications
• Ensuring request and response conformity to the specification

Installation

$ go get -u github.com/ashutoshgngwr/goatkeeper

Usage

spec, err := ioutil.ReadFile("./openapi-spec.yaml")
if err != nil {
  panic("unable to read openapi spec file")
}

middleware, err := goatkeeper.NewMiddlware(
  &goatkeeper.MiddlewareOptions{
    OpenAPISpec:      spec,
    ValidateResponse: true,
  })

if err != nil {
  panic("unable to initialize goatkeeper middleware")
}

With Gorilla mux

r := mux.NewRouter()
r.Use(middleware)
// r.Handle ...

With vanilla Golang

s := &http.Server{
  Addr:    ":8080",
  Handler: middlware(myAPIHandler),
}

log.Fatal(s.ListenAndServe())
