Define your models once — get TypeScript types, runtime validation, and DB metadata from a single .as model.
Documentation · Database Guide
Generic database abstraction layer for Atscript. Provides unified CRUD, relations, views, aggregations, and schema sync — all driven by @db.* annotations in your .as models. Pluggable adapters connect any database engine (SQLite, PostgreSQL, MongoDB, MySQL).
pnpm add @atscript/db@db.table "users"
interface User {
@meta.id
@db.default.increment
id: number
@db.index.unique "email_idx"
email: string
name: string
}
import { DbSpace } from "@atscript/db";
import { createAdapter } from "@atscript/db-sqlite";
const db = createAdapter("./myapp.db");
const users = db.getTable(User);
await users.insertOne({ name: "John", email: "john@example.com" });
const all = await users.findMany({ filter: { name: { $eq: "John" } } });| Entry | Purpose |

Annotation helpers for adapter plugins |
- Annotation-driven schema: table names, indexes, column mappings, defaults, primary keys
- Pluggable adapters via
BaseDbAdapter— same code works with any database - Automatic write pipeline: defaults, validation, ID preparation, column mapping
- Embedded object flattening (
__-separated columns) and@db.jsonstorage - Relations:
@db.rel.to,@db.rel.from,@db.rel.viawith nested writes - Views:
@db.viewwith joins, filters, materialized views, aggregation - Schema sync: FNV-1a hash drift detection, distributed locking, column/table renames
- Array patch operations:
$insert,$upsert,$update,$remove,$replace - Type-safe queries with
FlatOf<T>for autocomplete on filters and projections
