Algorand Reader v1.1.3

Algorand reader provides a set of functions to read the Algorand blockchain status. It allows to get balances, check opt-in, get nft metadata ARC-69 compliant and more.

Installing

Install the package

npm install algorand-reader

Requisites

Most of the functions requires a provider like an Algodv2 client and an Index client. You could provide a custom client or initialize an know service provider like Algonode or use sandbox.

// Simple start with Algonode
import { Reader, ENetworks, AlgoNode } from 'algorand-reader'
const provider = new AlgoNode(ENetworks.TESTNET)
const reader = new Reader(provider)

// OR with Sandbox
import { Reader, ENetworks, Sandbox } from 'algorand-reader'
const provider = new Sandbox()
const reader = new Reader(provider)

// OR using a custom provider
import { Reader, ENetworks, Provider } from 'algorand-reader'
const provider = new Provider(
  'a'.repeat(64), // Algodv2-token
  'http://localhost', // Algodv2-server
  4001, // Algodv2-port
  '', // Indexer-token
  'http://localhost', // Indexer-server
  8980 // Indexer-port
)
const reader = new Reader(provider)

await reader.getAsaBalance(address, asaId)

// Check if the account is opted-in to an asa
await reader.isOptIn(address, asaId)

// Get circulating supply of an asa
await reader.getTokenCirculatingSupply(testId)

// Get metadata from an asa with ARC-69 standard
const nftId = 117345116
await reader.getAssetMetadata(indexerClient, nftId)
