A module with a better and standard API exists
The new k6/experimental/websockets API partially implements the WebSockets API living standard.
When possible, we recommend using the new API. It uses a global event loop for consistency with other k6 APIs and better performance.
Call a function repeatedly, while the WebSocket connection is open.
Parameter | Type | Description |
---|---|---|
