Weston Pace 1a449fa49e refactor: rename drop_db / drop_database to drop_all_tables, expose database from connection (#2098)
If we start supporting external catalogs then "drop database" may be
misleading (and not possible). We should be more clear that this is a
utility method to drop all tables. This is also a nice chance for some
consistency cleanup as it was `drop_db` in rust, `drop_database` in
python, and non-existent in typescript.

This PR also adds a public accessor to get the database trait from a
connection.

BREAKING CHANGE: the `drop_database` / `drop_db` methods are now
deprecated.

LanceDB JavaScript SDK

A JavaScript library for LanceDB.

Installation

npm install @lancedb/lancedb

This will download the appropriate native library for your platform. We currently support:

  • Linux (x86_64 and aarch64)
  • MacOS (Intel and ARM/M1/M2)
  • Windows (x86_64 only)

We do not yet support musl-based Linux (such as Alpine Linux) or aarch64 Windows.

Usage

Basic Example

import * as lancedb from "@lancedb/lancedb";
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.vectorSearch([0.1, 0.3]).limit(20).toArray();
console.log(results);

The quickstart contains a more complete example.
