Reed Loden f23327af79 fix: use SPDX-compliant license name for nodejs packages (#2558)
Update license field from `Apache 2.0` to be `Apache-2.0` for all
Node.js packages.

This was causing GitHub's Dependency Review license check to fail with:
> The validity of the licenses of the dependencies below could not be
determined. Ensure that they are valid SPDX licenses

LanceDB JavaScript SDK

A JavaScript library for LanceDB.

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

  • Linux (x86_64 and aarch64 on glibc and musl)
  • MacOS (Intel and ARM/M1/M2)
  • Windows (x86_64 and aarch64)

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.
