## Summary `tokenizer` is a documented option, but initialization always passed the model name to `AutoTokenizer.from_pretrained`. Preserve the resolved tokenizer option, fall back to the model name when it is omitted, and identify the selected tokenizer in loading errors. Add five initialization regressions covering default model/tokenizer selection, an explicit tokenizer, registry variables, and tokenizer loading errors. They run in native Node child processes so the real ESM import works without changing Jest/CI flags. Model loaders are mocked and local/remote model access is disabled; these tests do not download models or test inference. ## Validation - Before: three regressions fail and two default-selection controls pass. After: all five pass. - New tests plus the existing registry and embedding-registry suites: 48 passed. - TypeScript compilation, changed-file Biome checks, and `pnpm run docs` pass; generated tracked docs are unchanged. - Checked with Node 24.14.1 / pnpm 11.1.1 on Linux, both with default Jest flags and the Linux CI ESM flag. The native binding and declarations came from the official `0.40.0-beta.13` packages, with registry integrity verified. Rebuilding Rust from source timed out during Cargo metadata resolution, before compilation; no Rust code is changed.
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);
