ar-io sdk

The ar.io SDK provides functionality for interacting with the ar.io ecosystem of services (e.g. gateways and observers) and protocols (e.g. ArNS). It is available for both NodeJS and Web environments.

Prerequisites

• node>=v18.0.0
• npm or yarn

Installation

npm install @ar.io/sdk

or

yarn add @ar.io/sdk --ignore-engines

NOTE: The --ignore-engines flag i required when using yarn, as permaweb/aoconnect (opens new window) recommends only the use of npm. Alternatively, you can add a .yarnrc.yml file to your project containing ignore-engines true to ignore the engine check.

Quick Start

Loading the gateway list in NodeJS.

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

const ario = ARIO.init();
const gateways = await ario.getGateways();

console.log(gateways);

Output

Usage

The SDK is provided in both CommonJS and ESM formats and is compatible with bundlers such as Webpack, Rollup, and ESbuild. Utilize the appropriately named exports provided by this SDK's package.json (opens new window) based on your project's configuration. Refer to the examples (opens new window) directory to see how to use the SDK in various environments.

Web

Bundlers (Webpack, Rollup, ESbuild, etc.)

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

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

Note: polyfills are only provided when using the named @ar.io/sdk/web export (which requires moduleResolution: nodenext in tsconfig.json). If you are using the default export within a Typescript project (e.g. moduleResolution: node), you will need to provide your own polyfills - specifically crypto, fs and buffer. Refer to examples/webpack (opens new window) and examples/vite (opens new window) for references in how to properly provide those polyfills. For other project configurations, refer to your bundler's documentation for more information on how to provide the necessary polyfills.

Browser

<script type="module">
  import { ARIO } from 'https://unpkg.com/@ar.io/sdk';

  // set up client
  const ario = ARIO.init();
  // fetch gateways
  const gateways = await ario.getGateways();
</script>

Node

ESM (NodeNext)

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

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

CJS

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

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

Typescript

The SDK provides TypeScript types. When you import the SDK in a TypeScript project types are exported from ./lib/types/[node/web]/index.d.ts and should be automatically recognized by package managers, offering benefits such as type-checking and autocompletion.

NOTE: Typescript version 5.3 or higher is recommended.

ARIO Token & mARIO Token

The ArIO contract stores all values as mARIO (milli-ARIO) to avoid floating-point arithmetic issues. The SDK provides an IOToken and mIOToken classes to handle the conversion between ARIO and mARIO, along with rounding logic for precision.

All contract interactions expect values in mARIO. If numbers are provided as inputs, they are assumed to be in raw mARIO values.

Converting ARIO to mARIO

import { ARIOToken, mARIOToken } from '@ar.io/sdk';

const arioValue = 1;
const mARIOValue = new ARIOToken(arioValue).toMARIO();
console.log(mARIOValue); // 1000000 (mARIO)

const mARIOValue = 1_000_000;
const arioValue = new mARIOToken(mARIOValue).toARIO();
console.log(arioValue); // 1 (ARIO)

ARIO Process

APIs

init({ signer })

Factory function to that creates a read-only or writeable client. By providing a signer additional write APIs that require signing, like joinNetwork and delegateStake are available. By default, a read-only client is returned and no write APIs are available.

// read-only client
const ario = ARIO.init()

// read-write client for browser environments
const ario = ARIO.init({ signer: new ArConnectSigner(window.arweaveWallet, Arweave.init({}))});

// read-write client for node environments
const ario = ARIO.init({ signer: new ArweaveSigner(JWK) });

getInfo()

Retrieves the information of the ARIO process.

const ario = ARIO.init();
const info = await ario.getInfo();

Output

{
  "Name": "Testnet ARIO",
  "Ticker": "tARIO",
  "Owner": "QGWqtJdLLgm2ehFWiiPzMaoFLD50CnGuzZIPEdoDRGQ",
  "Denomination": 6,
  "Handlers": ["_eval", "_default_"], // full list of handlers, useful for debugging
  "LastTickedEpochIndex": 31 // epoch index of the last tick
}

getTokenSupply()

Retrieves the total supply of tokens, returned in mARIO. The total supply includes the following:

• total - the total supply of all tokens
• circulating - the total supply minus locked, withdrawn, delegated, and staked
• locked - tokens that are locked in the protocol (a.k.a. vaulted)
• withdrawn - tokens that have been withdrawn from the protocol by operators and delegators
• delegated - tokens that have been delegated to gateways
• staked - tokens that are staked in the protocol by gateway operators
• protocolBalance - tokens that are held in the protocol's treasury. This is included in the circulating supply

const ario = ARIO.init();
const supply = await ario.getTokenSupply();

Output

{

const balance = await ario
  .getBalance({
    address: 'QGWqtJdLLgm2ehFWiiPzMaoFLD50CnGuzZIPEdoDRGQ',
  })
  .then((balance: number) => new mARIOToken(balance).toARIO()); // convert it to ARIO for readability

Output

// value in ARIO
1_000_000

Configuration

The ARIO client class exposes APIs relevenat to the ar.io process. It can be configured to use any AO Process ID that adheres to the ARIO Network Spec (opens new window). By default, it will use the current ARIO testnet process (opens new window). Refer to AO Connect (opens new window) for more information on how to configure an ARIO process to use specific AO infrastructure.

// provide a custom ao infrastructure and process id
const ario = ARIO.init({
  process: new AoProcess({
    processId: 'ARIO_PROCESS_ID'
    ao: connect({
      MU_URL: 'https://mu-testnet.xyz',
      CU_URL: 'https://cu-testnet.xyz',
      GRAPHQL_URL: 'https://arweave.net/graphql',
      GATEWAY_URL: 'https://arweave.net',
    })
  })
});

Arweave Name Tokens (ANT's)

The ANT client class exposes APIs relevant to compliant Arweave Name Token processes. It can be configured to use any process ID that adheres to the ANT process spec. You must provide either a custom process data provider or a processId to the ANT class constructor to use.

Configuration

ANT clients can be configured to use custom AO processes. Refer to AO Connect (opens new window) for more information on how to configure the AO process to use specific AO infrastructure.

const ant = ANT.init({
  process: new AoProcess({
    processId: 'ANT_PROCESS_ID'
    ao: connect({
      MU_URL: 'https://mu-testnet.xyz',
      CU_URL: 'https://cu-testnet.xyz',
      GRAPHQL_URL: 'https://arweave.net/graphql',
      GATEWAY_URL: 'https://arweave.net',
    })
  })
});

Logging

The library uses the Winston (opens new window) logger for node based projects, and console logger for web based projects by default. You can configure the log level via setLogLevel() API. Alternatively you can set a custom logger as the default logger so long as it satisfies the ILogger interface.

Configuration

import { Logger } from '@ar.io/sdk';

// set the log level
Logger.default.setLogLevel('debug');

// provide your own logger
Logger.default = winston.createLogger({ ...loggerConfigs }); // or some other logger that satisifes ILogger interface

Pagination

Certain APIs that could return a large amount of data are paginated using cursors. The SDK uses the cursor pattern (as opposed to pages) to better protect against changing data while paginating through a list of items. For more information on pagination strategies refer to this article (opens new window).

Paginated results include the following properties:

• items: the list of items on the current request, defaulted to 100 items.
• nextCursor: the cursor to use for the next batch of items. This is undefined if there are no more items to fetch.
• hasMore: a boolean indicating if there are more items to fetch. This is false if there are no more items to fetch.
• totalItems: the total number of items available. This may change as new items are added to the list, only use this for informational purposes.
• sortBy: the field used to sort the items, by default this is startTimestamp.
• sortOrder: the order used to sort the items, by default this is desc.

To request all the items in a list, you can iterate through the list using the nextCursor until hasMore is false.

let hasMore = true;
let cursor: string | undefined;
const gateaways = [];
while (hasMore) {
  const page = await io.getGateways({ limit: 10, cursor });
  gateaways.push(...items);
  cursor = page.nextCursor;
  hasMore = page.hasMore;
}

Resources

Bundling

For ANS-104 (opens new window) bundling compatible with ar.io gateways, we recommend using turbo-sdk (opens new window). Turbo SDK provides efficient and reliable methods for creating and uploading data bundles to the Arweave network, which are fully compatible with ar.io gateways. Turbo supports fiat and crypto bundling and uploading with a focus on ease of use and reliability.

Gateways

Running a Gateway

To run your own ar.io gateway, you can refer to the following resources:

• ar-io-node repository (opens new window): This repository contains the source code and instructions for setting up and running an ar.io gateway node.
• ar.io Gateway Documentation (opens new window): This comprehensive guide provides detailed information on gateway setup, configuration, and management.

Running your own gateway allows you to participate in the ar.io network, serve Arweave data, and potentially earn rewards. Make sure to follow the official documentation for the most up-to-date and accurate information on gateway operation.

AO

This library integrates with AO (opens new window), a decentralized compute platform built on Arweave. We utilize AO Connect (opens new window) to interact with AO processes and messages. This integration allows for seamless communication with the AO network, enabling developers to leverage decentralized computation and storage capabilities in their applications.

For more information on how to use AO and AO Connect within this library, please refer to our documentation and examples.
