Ethers.js - Node RPC Integration
Ethers.js is a standalone Typescript/Javascript for interacting with the Ethereum blockchain and its ecosystem.
To connect to a network through Node RPC using Ethers 6 or 5, you can use the JSON-RPC provider backed by HTTPS or WebSockets.

// Installation Instructions: https://docs.ethers.io/v6/getting-started
import { ethers } from "ethers";
const RPC_URL = `https://mainnet.gateway.tenderly.co/${process.env.TENDERLY_NODE_ACCESS_KEY}`
async function executeMethod() {
// Initialize an ethers provider instance
const provider = new ethers.JsonRpcProvider(RPC_URL);
const blockNumber = await provider.getBlockNumber();
console.log(blockNumber);
}
await executeMethod();Using WebSocket provider
