Format

useFetchMarketCode

const { isLoading, marketCodes } = useFetchMarketCode();

Return	Description	Type	Format
isLoading	State of fetching market codes data	Boolean	true : Loading, false : Done
marketCodes	All market codes of Upbit	ObjectArray	{ market: string, korean_name: string, english_name: string } [ ]

useUpbitWebSocket

const { socket, isConnected, socketData } = useUpbitWebSocket(
  targetMarketCodes,
  type,
  option
);

Default Value

targetMarketCodes : [
  { market: "KRW-BTC", korean_name: "비트코인", english_name: "Bitcoin" },
]
type : "ticker"
option : { throttle_time: 400, max_length_queue: 100 }

Argument	Description	Type	Format
targetMarketCodes	Targeted market codes to Websocket API	ObjectArray	{ market: string, korean_name: string, english_name: string} [ ] - targetMarketCodes should be strictly Object Array, not Object .
type	Websocket Connection Type	String	"ticker" "orderbook" "trade" - Strictly above one of the three types above
option	throttle_time : period of updating socketData max_length_queue : In "trade" type, max length of trade history queue	Object	{ throttle_time: number, max_length_queue: number } - Too Low throttle_time (less than 400ms) may cause unexpectable bug. - Too Large max_length_queue can make too large memory use.

Return	Description	Type	Format
socket	WebSocket object which is created by useUpbitWebSocket	WebSocket object
isConnected	State of Websocket Connection	Boolean	- true : Connected - false : NonConnected
socketData	recieved data from upbit websocket server	ObjectArray
