First, import web3 as such:

const Web3 = require('web3')

Then instantiate a variable (in my case web3) and set a provider:

const web3 = new Web3(new Web3.providers.HttpProvider('https://mainnet.infura.io/INFURA_ACCESS_TOKEN:8545'))

Then you can use all the available web3 methods.

Hope it helped you!

This metod stopped working in browser right? It is telling about CORS headers – gkucmierz Nov 05 '18 at 15:41
@gkucmierz I think you have to use NodeJS. Browsers won't allow CORS unless it's HTTP(S) apparently. – Philip Rego Sep 16 '20 at 01:51
