Functions

init

pub fn init(path: String, wrapper: fn(WebSocketEvent) -> a) -> Cmd(
  a,
)

Initialize a websocket. These constructs are fully asynchronous, so you must provide a wrapper that takes a WebSocketEvent and turns it into a lustre message of your application.

send

pub fn send(ws: WebSocket, msg: String) -> Cmd(a)

Send a text message over the web socket. This is asynchronous. There is no expectation of a reply. See init. Only works on an Non-Closed socket. Returns a Cmd(a) that you must pass as second entry in the lustre update return.
