DEPRECATED! Do not use for new code. See websockets.cljc.

Creates ChannelServer.

Params:

• handshake-data-fn (Optional) - Used by sente for adding data at the handshake.
• server-adapter (Optional) - adapter for handling servers implemented by sente. Default is http-kit.
• client-id-fn (Optional) - returns a client id from the request.
• dependencies (Optional) - adds dependecies to the fulcro handler.
• valid-client-id-fn (Optional) - Function for validating websocket clients. Expects a client-id.
• transit-handlers (Optional) - Expects a map with :read and/or :write key containing a map of transit handlers,

message-received clj multimethod

The primary multi-method to define methods for in order to receive client messages.

notify-listeners clj

(notify-listeners f listeners ws-net cid)

post-handler clj

remove-listener clj

(remove-listener listeners listener)

route-handlers clj

(route-handlers {:keys [config request]} _match)

Route handler that is expected to be passed to :extra-routes when creating a Fulcro app. Route handlers will look at optionally look at :ws-origin-whitelist in your config file, and validate origins trying to make a ws connection. If :ws-origin-whitelist is nil, origins will not be checked. The :origin key will also be treated as a valid origin if checking is enabled.

Example: Both the values in :origin and :ws-origin-whitelist will pass. Any other origin will return 403.

{:origin "localhost:8080"
 :ws-origin-whitelist "www.example.io:3000"}

Origins will not be checked.

{:origin "localhost:8080"}

simple-channel-server clj

                       {:keys [handshake-data-fn server-adapter client-id-fn

                               transit-handlers]})

Creates a channel server that uses the default server parser (you can use defmutation, defquery-root, etc.) for incoming requests. Any dependencies you need in the parsing environment will be injected into the :ws-net entry in the parsing env. In other words: this function makes the channel server depend on your stated dependencies, and the channel server itself appears under :ws-net in the parsing env. Thus, any injected dependencies will be there as well.

Params:

• handshake-data-fn (Optional) - Used by sente for adding data at the handshake.
• server-adapter (Optional) - adapter for handling servers implemented by sente. Default is http-kit.
• client-id-fn (Optional) - returns a client id from the request.
• dependencies (Optional) - adds dependecies to the :ws-net entry in the parsing environment.
• valid-client-id-fn (Optional) - Function for validating websocket clients. Expects a client-id.
• transit-handlers (Optional) - Expects a map with :read and/or :write key containing a map of transit handlers,

valid-client-id-atom clj

valid-client-id? clj

(valid-client-id? client-id)

Validate that the client id is a guid.

valid-origin? clj

(valid-origin? config request)

Validates origin based on a collection of whitelisted origin strings received from the config at :ws-origin-whitelist.
