Bitget TypeScript SDK example: ws-public.ts

Bitget V2 Classic WebSocket websocket public example for the Siebly Bitget SDK, with TypeScript source for exchange REST API and WebSocket integration, setup, and production SDK docs.

What This Example Covers

Bitget WebSocket stream example in TypeScript.
Uses the Siebly Bitget SDK package bitget-api instead of hand-written WebSocket plumbing.
Source path: Bitget/V2 - Classic/Websocket/ws-public.ts.
Example category: V2 Classic WebSocket.
Imports SDK symbols including DefaultLogger, WebsocketClientV2, WS_KEY_MAP.
Calls SDK methods such as on(), subscribeTopic(), getWsStore().

How To Use This Example

Start here for the specific request or stream pattern, then check the matching SDK guide for install, credentials, and operational notes.
For WebSocket examples, keep reconnect, resubscribe, heartbeat, and event-handler behavior explicit in your service.

  wsClient.on('update', (data) => {
    console.log('WS raw message received ', data);
    // console.log('WS raw message received ', JSON.stringify(data, null, 2));
  });

  wsClient.on('open', (data) => {
    console.log('WS connection opened:', data.wsKey);
  });
  wsClient.on('response', (data) => {
    console.log('WS response: ', JSON.stringify(data, null, 2));
  });
  wsClient.on('reconnect', ({ wsKey }) => {
