Tools needed:

Node.js
NPM
VS Code

Create a new repository, initialize NPM, and install the XRPL.js package:

mkdir helloWorld
cd helloWorld
npm init
npm i xrpl

Create a new app.js file in the repository:

touch app.js

Open the file and paste this code into it:

// Pull the XRPL package into the file
const XRPL = require('xrpl');

// Create an async function to console log of the ledger index
const displayLastLedgerIndex = async () => {
  // Connect to the XRPL client via a desired network
  const client = new XRPL.Client('wss://xrplcluster.com');
  await client.connect();

  // Request XRPL client information
  const ledgerInfo = await client.request({
    command: 'ledger',
    ledger_index: 'validated',
  });

  // Console log the ledger index
  console.log(`Hello World, from the XRPL. The last index was: ${ledgerInfo.result.ledger_index}`);

  // Disconnect from the XRPL client
  await client.disconnect();
};

// Call the async function
displayLastLedgerIndex();

Now, run this code:

node app.js
