NFT Fetcher and MongoDB Storage

This project fetches Non-Fungible Tokens (NFTs) issued by a specified project on the XRP Ledger and stores them in a MongoDB collection. The stored data includes the NFTokenID, owner address, URI pointing to the metadata file, and the contents of the metadata file.

Features

• Fetch NFTs from the XRP Ledger using xrpl.js.
• Retrieve and store metadata associated with each NFT.
• Store NFT data in a MongoDB database.

Prerequisites

• Node.js (version 14 or higher)
• MongoDB (local or remote instance)

Setup

1. Clone the Repository

git clone https://github.com/LetsEffingGo/XRPL-NFT-DB-Builder.git
cd XRPL-NFT-DB-Builder

2. Install Dependencies

npm install

This command installs the required packages, including xrpl, mongodb, and axios.

3. Configure the Environment

Ensure you have a MongoDB instance running.

sudo systemctl start mongod

You can either use a local MongoDB instance or a remote instance like MongoDB Atlas.

4. Run the Script

node dbBuilder.js

This script fetches NFTs issued by the specified XRP Ledger account and taxon, retrieves the metadata, and stores the data in MongoDB.

Configuration

• XRPL Settings: Update the issuerAddress and taxon in the script (index.js) to match your project's details.
• MongoDB Connection: Modify the mongoUri, dbName, and collectionName as needed.

const JSON_RPC_URL = "https://s1.ripple.com:51234/";
const issuerAddress = "[ISSUER_ADDRESS_HERE]";
const taxon = [COLLECTION_TAXON_HERE];
const mongoUri = "mongodb://localhost:27017/";
const dbName = "nft_db";
const collectionName = "nft_collection";

Usage

1. Ensure MongoDB is Running:

   • For a local instance, ensure the MongoDB service (mongod) is running.
   • For a remote instance, make sure you have the correct connection string and access credentials.

2. Fetch and Store NFTs:

   • Run the script as described above to fetch NFTs and store them in MongoDB.

Troubleshooting

• Connection Issues: Ensure that the MongoDB connection string is correct and that your MongoDB server is running.
• Fetching Metadata: If there are issues with fetching metadata, check the URI format and ensure the data is accessible.
