@NiklasFeurstein, further discussion available at Discussion Room. – Rudrika Sep 3 '19 at 5:42
I think this is what you are looking for:
const Web3 = require('web3');
const web3 = new Web3('wss://ropsten.infura.io/ws/v3/<yourID>');
const abi = "placeYourABI";
const address = 'yourContractAddress';
const contract = new web3.eth.Contract(abi, address);
contract.getPastEvents('allEvents', {
fromBlock: 0,
toBlock: 'latest'
}).then(function(events){
console.log(events);
});
Replace the variables. Take note of the URL. Websocket URL is not only different by wss at the front.
This code is tested and surely works.
EDIT: Please write why you downvote this answer! It is completely correct.
