XuanwoandEC2 Default User 8d10f25121 feat(nodejs): expose structured job progress (#4815)
TypeScript job handles now expose structured progress through
`progress()` and an optional synchronous callback to `wait()`. Snapshots
preserve unknown fields and missing counters, and job listings include
progress and pause state. Existing `status()` strings and no-argument
`wait()` behavior remain compatible.

Wait callbacks observe the existing backend poller. Observer exceptions
are logged without changing the job outcome. A best-effort ETA is
available only from compatible samples with positive progress, and is
omitted during initialization, queueing, or pause.

Part of ENT-3500.

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 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 more complete examples.
