Fixes #3269. ## What I observed Using a reranker in a hybrid query could keep the Node.js process alive even after `table.close()` and `db.close()`. ## Root cause The reranker callback bridge used a `ThreadsafeFunction` in referenced mode, which can keep the event loop alive longer than intended. ## Minimal fix - In `nodejs/src/rerankers.rs`, create the reranker callback TSFN in weak mode (`.weak::<true>()`). - Add a regression test in `nodejs/__test__/rerankers.test.ts` that spawns a child process, runs a rerank query, and asserts the process exits naturally. ## Validation - Built Node bindings successfully. - Ran targeted tests: `rerankers.test.ts` passes (including new regression test). - Pre-commit checks for changed files were run and clean.
LanceDB JavaScript SDK
A JavaScript library for LanceDB.
Installation

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);
