JavaScript Qdrant gRPC Client

This repository contains the gRPC client for the Qdrant vector search engine.

Installation

npm install @qdrant/js-client-grpc
# or
yarn add @qdrant/js-client-grpc
# or
pnpm i @qdrant/js-client-grpc

Usage

Run the Qdrant Docker container:

docker run -p 6334:6334 qdrant/qdrant

Instantiate a client

import {QdrantClient} from '@qdrant/js-client-grpc';

const client = new QdrantClient({host: '127.0.0.1', port: 6334});
// or
const client = new QdrantClient({url: 'http://127.0.0.1:6334'});

Make requests

Use an endpoint from collections API:

try {
    const result = await client.api('collections').list({});
    console.log('List of collections:', result.collections);
} catch (err) {
    console.error('Could not get collections:', err);
}

Support

The gRPC implementation relies on the native node module node:https. For the time being, no JavaScript runtime other than Node / Deno are supported (though support for web may be added). Both Deno and Node support full-duplex, HTTP trailers and all the necessary bits for gRPC. Under the hood, the client uses connect-es to communicate with the server.

Releases

Major and minor versions align with Qdrant's engine releases, whilst patch are reserved for fixes regarding the current minor release. Check out RELEASE.md for more info on release guidelines.
