snowflake-promise

A Promise-based interface to your Snowflake data warehouse.

This is a wrapper for the Snowflake SDK for Node.js. It provides a Promise-based API instead of the core callback-based API.

Installation

npm i snowflake-promise

Basic usage

const Snowflake = require('snowflake-promise').Snowflake;
// or, for TypeScript:
import { Snowflake } from 'snowflake-promise';

async function main() {
  const snowflake = new Snowflake({
    account: '<account name>',
    username: '<username>',
    password: '<password>',
    database: 'SNOWFLAKE_SAMPLE_DATA',
    schema: 'TPCH_SF1',
    warehouse: 'DEMO_WH'
  });

  await snowflake.connect();

  const rows = await snowflake.execute(
    'SELECT COUNT(*) FROM CUSTOMER WHERE C_MKTSEGMENT=:1',
    ['AUTOMOBILE']
  );

  console.log(rows);
}

main();

• Streaming result rows
• Using traditional Promise then syntax (and older versions of Node.js)
  • Node 4.0.0 is the oldest supported version
• Turn on logging
