Changelog

3.X

• 3.0.2

  • Re-re-re-re-re-added in ping-pong timer. Child sockets will also send ping/pongs through their parent sockets and BitMEX side is cool with that.
  • Started adding proper notation for functions.
  • Bug Fix: this in place of variable refernce in function.

• 3.0.1

  • Bug Fix: standalone: true ignored the autoconn: true option.

• 3.0.0

  • Added DOCS.md
  • Another Complete rewrite. Five minutes into a bot and the flaws of the last one were apparent.

2.X

• 2.1.0
  • Added full object breakdown for the objects this library exports.
  • Removed stream.reply() and socket.command() in lieu of internal event messages _download and _upload. stream.on('_download', type, reply) for all raw messages received on the socket. To send commands back stream.emit('_upload', { }) with the object being a valid message to BitMEX. { op: "subscribe", args: "trade" } for example. To change the message type, add a type item to the object. { type: 2 } sends an empty dc message.
  • Subscriptions to specific channels (trade:XBTUSD) now emit their events under the global table and emit a second param for the channel. stream.on('subscribe', (table, channel) => {}) If channel is omitted, it's the global table subscribe(table), otherwise it's a specific one subscribe(table:symbol).
  • Added REST API to BitmexStream object. stream.send(dir, type = 'GET', data = {}). Streams that have authenticated on the socket may also perform private REST functions such as making new orders or whatever other permissions the API key allows.
• 2.0.2
  • Fixed bug in stream.on('partial|insert|update|delete', (table, data, row) => {}): data was sending wrong data object.
  • Added force param to stream.authenticate(key, secret, force = false): stream.authenticate() won't add the authenticate message to socket queue if stream isn't already connected unless force is true. It will however add the supplied key/secret to the secureContext for authentication later if connect() is called manually.
  • Added changelog.
• 2.0.1
  • Added ping/pong back for main socket.
  • Improved docs somewhat with examples on disconnect() and connect()
• 2.0.0
  • Complete rewrite and simplification of base library.
