@boarteam/fix-dict-fixt11

The FIXT.1.1 transport-layer dictionary as data (74 fields / 7 session messages / 4 components) for the @boarteam/fix engine. FIXT.1.1 is the session protocol that carries FIX 5.0+ application messages: the standard header/trailer (a strict superset of the FIX 4.4 envelope, adding ApplVerID(1128), CstmApplVerID(1129), ApplExtID(1156)), plus the session messages — Heartbeat(0), TestRequest(1), ResendRequest(2), Reject(3), SequenceReset(4), Logout(5), and Logon(A) with its required DefaultApplVerID(1137). Generated from the QuickFIX/J FIXT11.xml data dictionary — never hand-maintained.

Use it for transport-layer tooling (session-message construction and validation, layer attribution) or pair it with an application dictionary. For a batteries-included FIX 5.0 SP2 dictionary that already contains this envelope, use @boarteam/fix-dict-fix50sp2.

import { createFixEngine } from '@boarteam/fix';
import { dictionary, message, Enums } from '@boarteam/fix-dict-fixt11';

const fix = createFixEngine(dictionary);
// A typed FIXT Logon: DefaultApplVerID(1137) is REQUIRED by the LogonBody type.
const wire = message('A')
  .set('EncryptMethod', '0')
  .set('HeartBtInt', 30)
  .set('DefaultApplVerID', Enums.ApplVerID.FIX50SP2) // '9'
  .render({
    SenderCompID: 'ME',
    TargetCompID: 'YOU',
    MsgSeqNum: 1,
    SendingTime: '20260801-12:00:00',
  });

Exports: dictionary (the data; version === beginString === 'FIXT.1.1'), Tags/TagNames, MsgType/MsgTypeNames, Enums (e.g. Enums.ApplVerID, Enums.SessionRejectReason), a top-level const + same-name type per enumerated field, DICTIONARY_VERSION, and the typed message API (message, MessageBodies with the 7 admin bodies, isMessageType, MessageOf<M>).

Provenance & coverage

• Structure: QuickFIX/J FIXT11.xml (vendored at a pinned commit; provenance and SHA-256 recorded in the generator repo). Header: 30 members including the HopGrp (NoHops) component; trailer: SignatureLength/Signature/CheckSum.
• Descriptions: FIX Orchestra FIXTSession.xml (FIX.5.0SP2_EP247, Apache-2.0). 73/74 fields are documented; MsgType(35) enumerates the full FIX 5.0 message-type code set but only the session-layer codes carry session-layer descriptions (recorded in dictionary.coverageGaps).
• Known limitation: XMLnonFIX(n) is deliberately not shipped: QuickFIX/J master comments it out and quickfix-go omits it entirely; only quickfix C++ ships it. Restoring it later is additive (a minor release); shipping it now and dropping it later would be breaking. Messages carrying 35=n parse flat with a parse/unknown-msgtype issue.

Requires @boarteam/fix as a peer dependency.
