Constants

const API_SUB_PATH = "/api/v1"

the sub path any API's are served over

const CONTEXT_ADDRESS = "address"

the context name we keep the address

const WEBSOCKET_SUB_PATH = "/ws"

the sub path the websocket server is mounted on

const X_LILYPAD_SIGNATURE_HEADER = "X-Lilypad-Signature"

this is the signature of the message

const X_LILYPAD_USER_HEADER = "X-Lilypad-User"

write some string constants for x-lilypad headers this is the address of the user

Functions

func AddHeaders

func AddHeaders(
	req *retryablehttp.Request,
	privateKey *ecdsa.PrivateKey,
	address string,
) error

func ConnectWebSocket

func ConnectWebSocket(
	url string,
	messageChan chan []byte,
	ctx context.Context,
) *websocket.Conn

ConnectWebSocket establishes a new WebSocket connection

func CorsMiddleware

func CorsMiddleware(next http.Handler) http.Handler

func GetAddressFromHeaders

func GetAddressFromHeaders(req *http.Request) (string, error)

this will use the client headers to ensure that a message was signed by the holder of a private key for a specific address there is a "X-Lilypad-User" header that will contain the address there is a "X-Lilypad-Signature" header that will contain the signature we use the signature to verify that the message was signed by the private key

func GetHandler

func GetHandler[T any](handler httpGetWrapper[T]) func(res http.ResponseWriter, req *http.Request)

wrap a http handler with some error handling so if it returns an error we handle it
