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 | | Bool | boolean | | FilePos | bigint | | Missing | null | | AutoNumber | bigint | | UUID | string | | SHA1 | string |
