I have a little script just with the following function:

const Web3 = require('web3');
var web3Provider = new Web3(new Web3.providers.WebsocketProvider('ws://'));
const web3 = new Web3(web3Provider);

web3.eth.getAccounts().then(e => console.log(e));

But when I receive the callback, the script is never closed, it continues running (doing nothing). How can I stoped it? why it happens?


Unlike an HTTP connection, a WebSocket needs to be closed explicitly.

You can do it with:


Or more generally, with:

if (web3.currentProvider.constructor.name == "WebsocketProvider")

The latter will allow you to support both types of connection in your script.
