🖼🎑🌠

A utility to fetch and easily display Ethereum & Solana NFTs in a common format given any wallet.

built with ❤️ from the team @Audius.

Installation

# install peer dependencies if not already in your project
npm install @solana/spl-token @solana/web3.js

npm install @audius/fetch-nft

Basic Usage

import { FetchNFTClient } from "@audius/fetch-nft";

// Initialize fetch client
const fetchClient = new FetchNFTClient();

// Fetching all collectibles for the given wallets
fetchClient
  .getCollectibles({
    ethWallets: ["0x5A8443f456f490dceeAD0922B0Cc89AFd598cec9"],
    solWallets: ["GrWNH9qfwrvoCEoTm65hmnSh4z3CD96SfhtfQY6ZKUfY"],
  })
  .then((res) => console.log(res));

By default, fetch-nft uses the public Opensea API and the Solana mainnet RPC endpoint. To configure API keys and endpoints, see Usage With Configs.

Fetch Client

FetchNFTClient is the primary interface for using the library. When initializing the client, you may optionally pass in configs for the OpenSea and Helius clients used internally.

type OpenSeaConfig = {
  apiEndpoint?: string;
  apiKey?: string;
  assetLimit?: number;
  eventLimit?: number;
};

type HeliusConfig = {
  apiEndpoint?: string;
  apiKey?: string;
  limit?: number;
};

type FetchNFTClientProps = {
  openSeaConfig?: OpenSeaConfig;
  heliusConfig?: HeliusConfig;
  solanaConfig?: {
    rpcEndpoint?: string;
    metadataProgramId?: string;
  };
};

Main Functions

Getting Ethereum collectibles:

FetchNFTClient::getEthereumCollectibles(wallets: string[]) => Promise<CollectibleState>

Getting Solana collectibles:

FetchNFTClient::getSolanaCollectibles(wallets: string[]) => Promise<CollectibleState>

Getting all collectibles:

FetchNFTClient::getCollectibles({
  ethWallets?: string[],
  solWallets?: string[]
}) => Promise<{
  ethCollectibles: CollectibleState
  solCollectibles: CollectibleState
}>

Usage with Configs

import { FetchNFTClient } from '@audius/fetch-nft'

// OpenSea Config
const openSeaConfig = {
  apiEndpoint: '...',
  apiKey: '...',
  assetLimit: 10,
  eventLimit: 10
}

// Helius Config
const heliusConfig = {
  apiEndpoint: '...';
  apiKey: '...',
  limit: 10
}

const solanaConfig = {
  rpcEndpoint: '...',
  metadataProgramId: '...'
};

// Initialize fetch client with configs
const fetchClient = new FetchNFTClient({ openSeaConfig, heliusConfig, solanaConfig })

// Fetching Ethereum collectibles for the given wallets
fetchClient.getEthereumCollectibles([...]).then(res => console.log(res))

// Fetching Solana collectibles for the given wallets
fetchClient.getSolanaCollectibles([...]).then(res => console.log(res))
