module_function def connect_to_playwright_server(ws_endpoint, &block)
  require 'playwright/web_socket_client'
  require 'playwright/web_socket_transport'

  transport = WebSocketTransport.new(ws_endpoint: ws_endpoint)

  connection.async_run

    ensure
      execution.stop
    end
  else
    execution
  end
end

.create(playwright_cli_executable_path:, &block) ⇒ Object

Recommended to call this method with block.

Playwright.create(…) do |playwright|

browser = playwright.chromium.launch
...

end

When we use this method without block, an instance of Puppeteer::Execution is returned and we must call execution.stop on the end. The instance of playwright is available by calling execution.playwright
