BoxDB adapter for Drizzle

An asynchronous SQLite driver for Drizzle 0.45.x. Install @boxdb/client, @boxdb/drizzle-adapter, and drizzle-orm.

npm install @boxdb/client @boxdb/drizzle-adapter drizzle-orm

import { BoxDB } from "@boxdb/client";
import { createDrizzleDatabase, migrate } from "@boxdb/drizzle-adapter";
import { integer, sqliteTable, text } from "drizzle-orm/sqlite-core";

const users = sqliteTable("users", {
  id: integer().primaryKey({ autoIncrement: true }).$type<bigint>(),
  name: text().notNull(),
});
await using client = await BoxDB.open("data.db");
const db = createDrizzleDatabase(client, { schema: { users } });
await migrate(db, { migrationsFolder: "./drizzle" });
const rows = await db.insert(users).values({ name: "Ada" }).returning();

The driver supports relational queries, joins, prepared Drizzle queries, RETURNING, and atomic batch. Drizzle transaction callbacks use BoxDB transaction handles internally; nested callbacks use savepoints. You can also pass an existing BoxDB transaction to createDrizzleDatabase.

Write metadata and integer cells remain bigint. Use integer().$type<bigint>() for Drizzle integer columns. Boolean columns map to boolean and timestamp columns map to Date, without converting unrelated integer cells. Migrations use an INTEGER journal and apply SQL and journal entries in one transaction.

The adapter borrows $client; close it yourself or use await using. For cancellation across Drizzle work, open a BoxDB transaction with a signal and create the Drizzle database from its handle. Base-client ownership rules apply when mixing Drizzle and direct SQL.

BoxDB columns

Declare extended types with the adapter's column builders:

import { decimal, instant, json, uuid } from "@boxdb/drizzle-adapter";

const invoices = sqliteTable("invoices", {
  id: uuid().primaryKey(),
  amount: decimal({ precision: 20, scale: 2 }).notNull(),
  createdAt: instant("created_at").notNull(),
  details: json().$type<{ reference: string }>(),
});

decimal, uuid, instant, date, time, dateTime and interval use strings for parameters and results. BoxDB validates and normalizes values in the declared SQL columns; exact decimals and temporal microseconds survive without conversion to JavaScript Number or Date. Builders expose the native SQL declarations for schema generation. time("opens") declares a TIME column, using values such as "09:30:00.000000" without a date or zone. Create matching columns through BoxDB migrations.

json serializes and parses complete documents in the client. $type<T>() describes the application type; it does not validate that shape at runtime. SQL NULL remains null. JSON/JSONB SQL inspection and editing are unsupported.
