@fast-firebird/drizzle

Drizzle ORM dialect and driver for Firebird 3/4/5/6, powered by @fast-firebird/core — pure TypeScript, zero native dependencies.

import { connect } from '@fast-firebird/core';
import { drizzle, firebirdTable, integer, varchar } from '@fast-firebird/drizzle';
import { eq } from 'drizzle-orm';

const users = firebirdTable('USERS', {
  id: integer('ID').primaryKey(),
  name: varchar('NAME', { length: 50 }),
});

const db = drizzle(await connect({ /* … */ }));

const rows = await db.select().from(users).where(eq(users.id, 1)).limit(10);

What works

• Query builder — select/insert/update/delete, joins, RETURNING, limit/offset translated to Firebird's FIRST/SKIP, multi-row inserts.
• All Firebird column types — including blobs (blob/blobText), timestamps, DECFLOAT, INT128.
• Transactions — db.transaction(), with nested transactions mapped to Firebird savepoints.
• Migrations — a plain-SQL migrator (migrate(db, { migrationsFolder })): lexicographic .sql files, per-statement commits (AUTODDL-style), tracked in a migrations table. drizzle-kit's generators are closed to third-party dialects, so migrations are hand-written SQL — which Firebird DBAs tend to prefer anyway.
• Introspection — introspectDatabase() reads the RDB$ system tables and generateDrizzleSchema() emits a ready-to-use schema file from an existing database.
• Relational queries — flat db.query.<table>.findMany()/findFirst() work; nested with: is rejected with a guidance error (Firebird has no JSON aggregation — planned via client-side decomposition, tracked in the repo).
