WebSocket Reference

The WebSocket interface provides framed, protocol-level messaging over an established TCP/TLS connection. The easy_handle must be converted to WebSocket mode before any send or receive operations can occur.

Setup

Method	Description	libcurl Reference
WebSocketConvert(easy_handle?)	Upgrades the handle to WebSocket mode, performing the handshake and configuring internal framing.	curl_ws_send
SetWebSocketFrameSize(frame_size := 10 * 1024, easy_handle?)	Configures the outgoing frame size limit (default 10 KB).	curl_ws_send

Transfer

Method	Description	libcurl Reference
WebSocketSend(content, flagArr := ["TEXT"], easy_handle?)	Transmits a framed WebSocket message. Accepts String, Integer, Object, Array, Map, and Buffer.	curl_ws_send
WebSocketReceive(easy_handle?)	Reads incoming WebSocket frames. Internally handles the CURL_WAITING_READY state.	curl_ws_recv
