websocket candles api nodejs

WebSocket Candles API for Node.js: Reconnect-Safe Setup

Integrate websocket candle feeds in Node.js with deterministic reconnect and stale-state handling.

Runnable example

Node.js websocket connection

const ws = new WebSocket(
  "wss://api.realmarketapi.com/ws/candles?ApiKey=YOUR_KEY&SymbolCode=BTCUSDT&TimeFrame=M1"
);
ws.onmessage = (evt) => console.log(evt.data);

Production notes

  • Add exponential backoff with jitter for reconnect attempts.
  • Expose clear disconnected/degraded UI states to end users.
  • Bound in-memory message buffers during outage recovery.
