cljs

(call! state kind)

(call! state kind params)

(call! state kind params handler & options)

Make a websocket RPC.

state - client or sever state (from create fn) connection-id - (server only) to select the client connection you want to call kind - used to dispatch behavior, typically a keyword params - (optional) any clj form (data) needed to support the :kind of request handler - (optional) (fn [RESPONSE]) invoked when a response to the request is received (reply? implied true)

OPTIONS - a map and/or key/value pairs:

close! clj/s≠

clj

(close! state connection-id)

Close the connection with connection-id

cljs

(close! state)

(close! state code-or-reason)

(close! state code reason)

Close the connection. code (optional) https://developer.mozilla.org/en-US/docs/Web/API/CloseEvent#status_codes reason (optional) A human-readable string explaining why the connection is closing

connect! cljs

(connect! client path csrf-token)

Open a websocket connection to the server.

client - client state atom path - URI path to the websocket handler. The protocol and host are determined by the window location. csrf-token - required for security. Default strategy is session/key from server.

connection clj/s

(connection id socket)

Returns a map holding connection data. A connection will contain, but is not limited to, these keys:

:id - a unique string id for the connection :socket - network communication channel :request-counter - to generate next request id in sequence for this connection :open? - boolean :responders - (maybe) map of request-id -> (fn [payload]) to handle responses :last-active-at - time of last send or receive of data

connection-request! clj/s

(connection-request! server conn-atom kind params responder)

connection-responder! clj/s

(connection-responder! conn-atom id)

create clj/s

(create message-handler & args)

Returns a atom to hold all the state and configuration to run a websocket client or server.

message-handler - (fn [REQUEST]) to handle incoming RPC requests.

REQUEST: :request-id - each connection has it's own sequence starting at 1 :kind - used to dispatch behavior (see BUILTIN KINDS below) :params - any clj form (data) needed to support the :kind of request :reply? - true iff a response is expected :connection-id - uniquely identifying the connection to the server :request - (server only) the ring request that initiated the websocket connection

BUILTIN KINDS (values for :kind key in requests) :ws/open - a connection is opened {:params nil} :ws/close - a connection is closed {:params nil} :ws/hello - sent from server to client when a connection is opened {:params nil} :ws/error - an error occurred {:params error-map} :ws/timeout - a request with {:reply? true} did not receive a response within :request-timeout milliseconds

RESPONSE: :response-id - id corresponding to originating request :payload - any form

OPTIONS - a map and/or key/value pairs: :on-data - (fn [data]) when incoming data fails to parse (edn) or satisfy request? or response? :request-timeout - (default: 5000) milliseconds to wait before cancelling request. nil -> never timeout. :atom-fn - (default: core/atom) type of atom to story the state. Maybe reagent/atom. :ping-interval - (default: 30) seconds between keep-alive pings on inactive connections. nil -> no pings

handler clj

(handler server request)
