The RelationalAI Software Development Kit for JavaScript

The RelationalAI (RAI) SDK for JavaScript enables developers to access the RAI REST APIs from JavaScript. The SDK provides first class TypeScript support.

• You can find RelationalAI product documentation at https://docs.relational.ai
• You can learn more about RelationalAI at https://relational.ai

Getting started

Requirements

• Node.js 14+

Installing the SDK

Install

$ npm install @relationalai/rai-sdk-javascript

Create a configuration file

In order to run the examples and, you will need to create an SDK config file. The default location for the file is $HOME/.rai/config and the file should include the following:

[default]
host = azure.relationalai.com
client_id = <your client_id>
client_secret = <your client secret>

# the following are all optional, with default values shown
# port = 443
# scheme = https
# client_credentials_url = https://login.relationalai.com/oauth/token

Client credentials can be created using the RAI console at https://console.relationalai.com/login

You can copy config.spec from the root of this repo and modify as needed.

Usage

The package provides readConfig helper that reads the configuration file

import { Client, readConfig } from '@relationalai/rai-sdk-javascript';

const config = await readConfig();
const client = new Client(config);

const result = await client.listEngines();

or you can build the config object

import { Client, ClientCredentials } from '@relationalai/rai-sdk-javascript';

const credentials = new ClientCredentials(
  'your client_id',
  'your client_secret',
  'https://login.relationalai.com/oauth/token',
);
const config = {
  credentials,
  host: 'azure.relationalai.com',
  scheme: 'https',
  port: '443',
};
const client = new Client(config);

const result = await client.listEngines();

Examples

Each of the example files in the ./examples folder is standalone and can be run from the command line, eg:

$ npm run example -- ./examples/listEngines.ts

$ npm run example -- ./examples/runQuery.ts -d dbName -e engineName -c "def output = 1 + 2"

Data Types

ResultTable maps Rel data types to their corresponding JavaScript equivalents. Full mapping:

Rel Data Type	JS Data Type
Int8, Int16, Int32	number
Int64, Int128	bigint
UInt8, UInt16, UInt32	number
UInt64, UInt128	bigint
Float16, Float32, Float64	number
Rational8, Rational16, Rational32	{ numerator: number; denominator: number; }
Rational64, Rational128	{ numerator: bigint; denominator: bigint; }
FixedDecimal all bit sizes(16, 32, 64, 128)	decimal.js
Char	string
String	string
DateTime, Date	Date
Year, Month, Week, Day	bigint
Hour, Minute, Second, Millisecond, Microsecond, Nanosecond	bigint
