NFT reader

Motivation

Abstract the NFTs data manipulation from the business logic. While NFTs can follow different ARC's, this library should abstract the ways of decoding metadata or digital media to show into the different marketplaces. The main idea is to handle metadata & digital media of the NFT easily, doesn't matter the ARC the NFT is following. You as client, should not understand the ARCs at all to develop under Algorand .

Supported ARCs

• ARC 0003
• ARC 0019
• ARC 0069

Available methods

Arc class:

• getStandard(): <arc3 | arc19 | arc69 | custom>
• getAssetMetadata()
• getAssetDigitalMedia()
• validateDigitalMediaIntegrity()
• validateMetadataIntegrity()

Examples

Installation

npm i nft-reader

Getting started

Typescript

import { NFTReader } from 'nft-reader';
const nftReader = new NFTReader({
    token: '',
    host: 'http://localhost',
    port: '8980',
});

Javascript vanilla

const { NFTReader } = require('nft-reader');

Getting metadata from ASA id

import { NFTReader } from 'nft-reader';
const nftReader = new NFTReader({
    token: '',
    host: 'http://localhost',
    port: '8980',
});
const asaId = 1;
const metadata = await nftReader.getAssetMetadata(asaId);
console.log(metadata);

From existing Indexer instance

import { Indexer } from 'algosdk';
const token  = "";
const server = "http://localhost";
const port   = 8980;
const indexerClient = new Indexer(token, server, port);

const nftReader = new NFTReader(indexerClient);

TODO:

• tests for integrity

• getStandard() should return an array of arcs

• extra-metadata support

• localization metadata field integrity check

• v2:

  • methods for creating NFTs following each ARC
