parseTpSlFrame

Parse a raw defilytics frame into a TpSlNotification, or null when the frame isn’t a report (control frames, malformed JSON, missing payload, or wrong shape). watchTpSlNotifications calls this on every inbound message; call it directly to parse frames you receive on your own socket.

The wire shape is single-wrapped — the data field is the payload, not a nested envelope:

{
  "app_name": "Hyper-EVM_COH-Low-Cap_Production",
  "primary_identifier": 9565,
  "secondary_identifier": 0,
  "address": "0xaE96…",
  "type": "report",
  "timestamp": 1782821982,
  "data": { "coh_quote_id": "…", "conditional_order_type": "…", "state": "…", "details": {}, "successful": true },
}

quoteId resolves to primary_identifier when non-zero, else falls back to secondary_identifier (the temp id).

import { parseTpSlFrame } from "@symmio/trading-core";
 
const frame = parseTpSlFrame(event.data);
if (frame) {
  console.log(frame.quoteId, frame.state, frame.successful);
}
