web3-net

What is web3-net?

The web3-net package is a sub-package of the web3.js library that provides network-related functionalities for interacting with Ethereum nodes. It allows developers to retrieve information about the network, such as the network ID, peer count, and listening status.

What are web3-net's main functionalities?

Get Network ID

This feature allows you to retrieve the network ID of the connected Ethereum network. The network ID is a unique identifier for different Ethereum networks (e.g., Mainnet, Ropsten, Rinkeby).

const Web3 = require('web3');
const web3 = new Web3('http://localhost:8545');
web3.eth.net.getId().then(console.log);

Get Peer Count

This feature allows you to get the number of peers currently connected to the Ethereum node. This can be useful for monitoring the health and connectivity of your node.

const Web3 = require('web3');
const web3 = new Web3('http://localhost:8545');
web3.eth.net.getPeerCount().then(console.log);

Check if Node is Listening

This feature checks if the Ethereum node is currently listening for network connections. It returns a boolean value indicating the listening status.

const Web3 = require('web3');
const web3 = new Web3('http://localhost:8545');
web3.eth.net.isListening().then(console.log);
