@fast-firebird/core

A next-generation Firebird SQL driver for Node.js — pure TypeScript, zero native dependencies, speaking the Firebird wire protocol directly (protocols 13–20) with first-class support for Firebird 3, 4, and 5 — plus Firebird 6 (snapshot, protocol 20).

import { connect } from '@fast-firebird/core';

const db = await connect({
  host: 'localhost',
  database: '/data/employees.fdb',
  user: 'SYSDBA',
  password: 'masterkey',
});

const rows = await db.query('select first 5 * from employee where salary > ?', [50000]);
await db.disconnect();

Highlights

• Fast on real networks — statement allocate+prepare pipelined into one round trip, execute+fetch coalesced, adaptive fetch batching, deferred cleanup ops. Attachment.roundTrips exposes the flush counter.
• Blobs done right — eager by default (a SELECT gives you values), 64KB segments with deep pipelining, FB5 inline blobs (small blobs cost zero extra round trips), lazy modes per column/subtype, blob.stream(), blob.toFile(), read-ahead for streaming consumers. 11–149× faster than legacy drivers on blob workloads.
• Modern auth & wire crypt — SRP256/SRP (Firebird's exact SRP-6a variant), ARC4/ChaCha/ChaCha64 wire encryption on by default, wire compression, Legacy_Auth fallback for old servers.
• Complete type system — all Firebird types including INT128, DECFLOAT 16/34 (±Inf/NaN), TIMESTAMP/TIME WITH TIME ZONE (instant or ZonedDate), NUMERIC precision handling, charset layer resolved at prepare time (including CHARSET NONE legacy databases via charsetNoneEncoding).
• Production plumbing — connection pool (validation-on-borrow, idle eviction), per-connection statement cache, row streaming with backpressure, multi-statement script execution (isql-compatible SET TERM), savepoint nested transactions, transaction restart/auto-upgrade, await using support, POST_EVENT listeners, Services API (server info, gstat, gbak backup/restore).
• Real error messages — the full gds→message table (2539 entries) with SQLSTATE and complete status vector on every FirebirdError.
• Tested against real servers — 1016 tests across a Firebird 3/4/5/6 (+ Legacy_Auth) Docker matrix on every push.
