Getting Started

Prerequisites

  • node >= v18.0.0
  • npm or yarn

Installation

Installation Methods

npm install @ar.io/sdk

Quick Start

The following examples demonstrate how to use the AR.IO SDK to retrieve a list of active gateways from the Gateway Address Registry (GAR) across different environments.

Node

Example Usage

import { ARIO } from '@ar.io/sdk/node'

// set up client
const ario = ARIO.init()
// fetch gateways
const gateways = await ario.getGateways()
console.log(gateways)

Web

Polyfills

Polyfills are not provided by default for bundled web projects (Vite, ESBuild, Webpack, Rollup, etc.) . Depending on your apps bundler configuration and plugins, you will need to provide polyfills for various imports including crypto, process and buffer. Refer to examples/webpack and examples/vite for examples. For other project configurations, refer to your bundler's documentation for more information on how to provide the necessary polyfills.

Environment Setup

import { ARIO } from '@ar.io/sdk/web'

// set up client
const ario = ARIO.init()
// fetch gateways
const gateways = await ario.getGateways()
console.log(gateways)

Output

The output for obtaining a list of gateways, regardless of the environment used, will follow the structure outlined below:
