	// contains filtered or unexported fields
}

ChiMiddleware is a handler that exposes prometheus metrics for the number of requests, the latency and the response size, partitioned by status code, method and HTTP path.

func NewChiMiddleware

func NewChiMiddleware(name string, buckets ...float64) *ChiMiddleware

NewMiddleware returns a new prometheus ChiMiddleware handler.

func (ChiMiddleware) Handler

func (c ChiMiddleware) Handler(next http.Handler) http.Handler

func (ChiMiddleware) Zero

func (c ChiMiddleware) Zero(codes []int, methods []string, paths []string)

type Handler

type Handler struct {
	// contains filtered or unexported fields
}

func New

func New(clientID, clientSecret, redirectURL string, frontendRenderer Renderer) *Handler

func (*Handler) RefreshCallback

func (h *Handler) RefreshCallback(w http.ResponseWriter, r *http.Request)

Token refresh helper endpoint. Takes a valid oauth2 token containing an access code and a refresh token, and returns a fresh token in return.

func (*JSONRenderer) Render

func (r *JSONRenderer) Render(w http.ResponseWriter, code int, err error, token *oauth2.Token)

type Renderer

type Renderer interface {
	Render(w http.ResponseWriter, code int, err error, token *oauth2.Token)
}

type Response

type Response struct {
	Error error  `json:"error,omitempty"`
	Token string `json:"token,omitempty"`
}

type TextRenderer
