Parameters

none

Response

boolean — a boolean value that indicates whether a node is actively seeking peer connections. true if the client is actively listening for connections, false if not.

`net_listening` code examples

const ethers = require('ethers');
const NODE_URL = "CHAINSTACK_NODE_URL";
const provider = new ethers.JsonRpcProvider(NODE_URL);

const isListening = async () => {
const listen = await provider.send("net_listening");
console.log(listen);
}

isListening()

from web3 import Web3  
node_url = "CHAINSTACK_NODE_URL"
web3 = Web3.HTTPProvider(node_url)

is_listening = web3.provider.make_request('net_listening', [])
print(is_listening)

Use case

A method like net_listening can be used to monitor the network status of the Fantom node a developer connects to. Imagine a blockchain explorer where users can search for transactions, addresses, and other information on the Ethereum blockchain. To provide accurate information to its users, the website needs to be able to monitor the current status of its connection.
