Overview

The ‘WebSocket` class represents WebSocket connections within a page. It provides the ability to inspect and manipulate the data being transmitted and received.

If you want to intercept or modify WebSocket frames, consider using ‘WebSocketRoute`.

Returns:

def closed?
  wrap_impl(@impl.closed?)
end

#expect_event(event, predicate: nil, timeout: nil, &block) ⇒ Object

Waits for event to fire and passes its value into the predicate function. Returns when the predicate returns truthy value. Will throw an error if the webSocket is closed before the event is fired. Returns the event data value.

#wait_for_event(event, predicate: nil, timeout: nil, &block) ⇒ Object

NOTE: In most cases, you should use [‘method: WebSocket.waitForEvent`].

Waits for given ‘event` to fire. If predicate is provided, it passes event’s value into the ‘predicate` function and waits for `predicate(event)` to return a truthy value. Will throw an error if the socket is closed before the `event` is fired.
