Quick Start

import { AingDB } from "@triyatna/aingdb";

const db = await AingDB.open({
  path: "./app.msdb",
  encryption: {
    enabled: true,
    algorithm: "aes-256-gcm",
    kdf: "scrypt",
    passphrase: "secret",
  },
});

await db.schema.create({
  name: "users",
  columns: [
    { name: "id", type: "uuid", primary: true },
    { name: "email", type: "string", unique: true },
    { name: "name", type: "text" },
  ],
});

await db.table("users").insert({ id: "u1", email: "[email protected]", name: "Ana" });
const rows = await db.table("users").find({ email: "[email protected]" });

await db.close();

Feature Highlights

• Encrypted single-file WAL + immutable audit trail
• SQL: SELECT + WITH CTE, INNER/LEFT JOIN, WHERE, GROUP BY + agregat, Window (ROW_NUMBER, RANK, DENSE_RANK, LAG/LEAD), ORDER BY, LIMIT, RETURNING
• Optimizer: cost-based (ringan) dengan ANALYZE stats, predicate pushdown, IndexScan vs SeqScan, nested-loop join index-aware
• Indexes: multi-kolom, partial (predicate), expression (mis. LOWER(email)), Index Advisor
• Vector: HNSW multi-level (cosine/L2), efSearch dinamis, persistensi graf
• Search: FTS-lite (MATCH()), RTREE-lite (INTERSECTS())
• Observability: /metrics (Prometheus), /healthz
