This will download the appropriate native library for your platform. We currently support x86_64 Linux, aarch64 Linux, Intel MacOS, and ARM (M1/M2) MacOS. We do not yet support Windows or musl-based Linux (such as Alpine Linux).

Usage

Basic Example

const db = await lancedb.connect('data/sample-lancedb');
const table = await db.createTable("my_table",
      [{ id: 1, vector: [0.1, 1.0], item: "foo", price: 10.0 },
      { id: 2, vector: [3.9, 0.5], item: "bar", price: 20.0 }])
const results = await table.search([0.1, 0.3]).limit(20).execute();
console.log(results);
