Types

type ApiHandlerFunc 

type ApiHandlerFunc func(
	r *request.Request,
	backend access.API,
	generator models.LinkGenerator,
) (interface{}, error)

ApiHandlerFunc is a function that contains endpoint handling logic, it fetches necessary resources and returns an error or response model.

type Handler 

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

Handler is custom http handler implementing custom handler function. Handler function allows easier handling of errors and responses as it wraps functionality for handling error and responses outside of endpoint handling.

func NewHandler 

func NewHandler(
	logger zerolog.Logger,
	backend access.API,
	handlerFunc ApiHandlerFunc,
	generator models.LinkGenerator,
	chain flow.Chain,
) *Handler

func (*Handler) ServeHTTP 

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

ServerHTTP function acts as a wrapper to each request providing common handling functionality such as logging, error handling, request decorators

type HttpHandler 

type HttpHandler struct {
	Logger zerolog.Logger
	Chain  flow.Chain
}

HttpHandler is custom http handler implementing custom handler function. HttpHandler function allows easier handling of errors and responses as it wraps functionality for handling error and responses outside of endpoint handling.

func NewHttpHandler 

func NewHttpHandler(
	logger zerolog.Logger,
	chain flow.Chain,
) *HttpHandler

func (*HttpHandler) VerifyRequest 

func (h *HttpHandler) VerifyRequest(w http.ResponseWriter, r *http.Request) error

VerifyRequest function acts as a wrapper to each request providing common handling functionality such as logging, error handling

type RouterBuilder 

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

RouterBuilder is a utility for building HTTP routers with common middleware and routes.

func NewRouterBuilder 

func NewRouterBuilder(
	logger zerolog.Logger,
	restCollector module.RestMetrics) *RouterBuilder

NewRouterBuilder creates a new RouterBuilder instance with common middleware and a v1 sub-router.

func (*RouterBuilder) AddRestRoutes 

func (b *RouterBuilder) AddRestRoutes(backend access.API, chain flow.Chain) *RouterBuilder

AddRestRoutes adds rest routes to the router.

func (*RouterBuilder) AddWsRoutes 

func (b *RouterBuilder) AddWsRoutes(
	stateStreamApi state_stream.API,
	chain flow.Chain,
	stateStreamConfig backend.Config,
) *RouterBuilder

AddWsRoutes adds WebSocket routes to the router.

func (*RouterBuilder) Build 

func (b *RouterBuilder) Build() *mux.Router

type SubscribeHandlerFunc 

type SubscribeHandlerFunc func(
	ctx context.Context,
	request *request.Request,
	wsController *WebsocketController,
) (subscription.Subscription, error)

SubscribeHandlerFunc is a function that contains endpoint handling logic for subscribes, fetches necessary resources

type WSHandler 

type WSHandler struct {
	*HttpHandler
	// contains filtered or unexported fields
}

WSHandler is websocket handler implementing custom websocket handler function and allows easier handling of errors and responses as it wraps functionality for handling error and responses outside of endpoint handling.

func NewWSHandler 

func NewWSHandler(
	logger zerolog.Logger,
	api state_stream.API,
	subscribeFunc SubscribeHandlerFunc,
	chain flow.Chain,
	stateStreamConfig backend.Config,
) *WSHandler

func (*WSHandler) ServeHTTP 

func (h *WSHandler) ServeHTTP(w http.ResponseWriter, r *http.Request)

ServeHTTP function acts as a wrapper to each request providing common handling functionality such as logging, error handling, request decorators

type WebsocketController 

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

WebsocketController holds the necessary components and parameters for handling a WebSocket subscription. It manages the communication between the server and the WebSocket client for subscribing.

func (*WebsocketController) SetWebsocketConf 

func (wsController *WebsocketController) SetWebsocketConf() error

SetWebsocketConf used to set read and write deadlines for WebSocket connections and establishes a Pong handler to manage incoming Pong messages. These methods allow to specify a time limit for reading from or writing to a WebSocket connection. If the operation (reading or writing) takes longer than the specified deadline, the connection will be closed.
