Package Exports

@lancedb/arrow-flight-sql-client
@lancedb/arrow-flight-sql-client/dist/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@lancedb/arrow-flight-sql-client) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

JavaScript Client for FlightSQL

This is a JavaScript client for FlightSQL. It allows you to easily query FlightSQL servers from your JavaScript applications.

Warning: This client is still experimental and in heavy development. If you'd like to help contribute, please reach out to us at the LanceDB Discord server.

Currently all testing is done on Node.

Installation

You can install the client using npm:

npm install @lancedb/flightsql-client

Usage

To use the client, you first need to connect to your database:

import { Client } from "@lancedb/flightsql-client";

const client = await Client.connect({
  host: "mydb.com:10025",
  username: "lancedb",
  password: "password",
});

Once you have connected to your database, you can run queries:

const result = await client.query("SELECT * FROM flights WHERE origin = 'SFO'");

Query results can be returned in a variety of formats but the simplest thing to do is to return them as an array of objects:

interface FlightRecord {
    origin: string;
    destination: string;
}

const flights = (await result.collectToObjects()) as FlightRecord[];
console.log(flights);
