# Start a local test validator
light test-validator

## ensure you have the Solana CLI accessible in your system PATH

// createRpc() defaults to local test validator endpoints
import {
  Rpc,
  createRpc,
} from "@lightprotocol/stateless.js";

const connection: Rpc = createRpc();

async function main() {
  let slot = await connection.getSlot();
  console.log(slot);

  let health = await connection.getIndexerHealth(slot);
  console.log(health);
  // "Ok"
}

main();

Devnet

Replace <your-api-key> with your actual API key. Get your API key here, if you don’t have one yet.

import { createRpc } from "@lightprotocol/stateless.js";

const RPC_ENDPOINT = "https://devnet.helius-rpc.com?api-key=<your_api_key>";
const connection = createRpc(RPC_ENDPOINT);

async function main() {
  let slot = await connection.getSlot();
  console.log(slot);

  let health = await connection.getIndexerHealth(slot);
  console.log(health);
  // "Ok"
}

main();
