@askdb/sqlite

SQLite integration for AskDB. Bundles three pieces:

1. Dialect — re-exports SQLITE_DIALECT from @askdb/core. Pass dialect: SQLITE_DIALECT to ask() to target SQLite.
2. Connector — createSqliteConnector() implements the Connector contract from @askdb/introspect for live introspection mode.
3. Catalog runner — createSqliteCatalogQueryRunner(filePath) returns an introspection-only CatalogQueryRunner backed by better-sqlite3 (peer dependency, lazy-loaded). Introspects via sqlite_master and PRAGMA functions. Requires SQLite ≥ 3.16.

Install

pnpm add @askdb/core @askdb/introspect @askdb/sqlite

better-sqlite3 is an optional peer dependency — install it only when using live introspection mode:

pnpm add better-sqlite3

For one-off CLI introspection, include the driver in the same ephemeral command:

pnpm dlx -p askdb -p better-sqlite3 askdb introspect --engine sqlite --url ./my-database.db
npx -p askdb -p better-sqlite3 askdb introspect --engine sqlite --url ./my-database.db

Usage

NL→SQL

import { ask, loadSchema } from "@askdb/core";
import { SQLITE_DIALECT } from "@askdb/sqlite";

const schema = loadSchema("./my-app.schema");

const { sql } = await ask({
  question: "How many paid orders were created last month?",
  schema,
  model,
  dialect: SQLITE_DIALECT,
});

Introspection

import { introspect } from "@askdb/introspect";
import { createSqliteConnector, createSqliteCatalogQueryRunner } from "@askdb/sqlite";

const result = await introspect(
  { mode: "live", runner: createSqliteCatalogQueryRunner("/path/to/database.db") },
  { outDir: "./my-app.schema", schemaId: "my-app" },
  { connector: createSqliteConnector() },
);

Captured metadata

Tables, views, columns (SQLite affinity type strings), primary keys, unique constraints, foreign keys, and indexes. Requires SQLite ≥ 3.16 for pragma_* table-valued functions.
