Function parseGeyserUpdate

parseGeyserUpdate(raw, config?): ParsedGeyserUpdate | null

Parse any raw Geyser subscription update into a typed discriminated union.

This is the main entry point — pass any raw update message from the gRPC stream and get back a fully parsed, typed object.

Parameters

raw: RawGeyserUpdate
The raw update object from the gRPC subscribe() stream.
config: GeyserParserConfig = {}
Optional parser configuration.

Returns ParsedGeyserUpdate | null

Parsed update with type discriminant, or null if the update was filtered out (e.g. vote transaction with skipVotes: true).

Example

import { parseGeyserUpdate } from '@oobe-protocol-labs/synapse-client-sdk/grpc';

stream.on('data', (raw) => {
  const parsed = parseGeyserUpdate(raw);
  if (!parsed) return; // filtered out

  switch (parsed.type) {
    case 'transaction':
      console.log(parsed.data.signature, parsed.data.programsInvoked);
      break;
    case 'account':
      console.log(parsed.data.pubkey, parsed.data.sol);
      break;
    case 'slot':
      console.log(parsed.data.slot, parsed.data.status);
      break;
  }
});
