Web3js – Web3js Not Connecting to TestRPC in Localhost

javascriptnodestestrpcweb3js

I am simply trying to run web3js in a node console and connect it to a testrpc running in localhost.

I run my testrpc like so:

> ganache-cli
Ganache CLI v6.0.3 (ganache-core: 2.0.2)

Listening on localhost:8545

This looks all good to me, I then open a tmux session and run the following lines in a simple node cli:

// Load Libraries
  var solc = require("solc");
  var fs = require("fs");
  var Web3 = require("web3");

// Connect Web3 Instance
  var web3 = new Web3(new Web3.providers.HttpProvider(`http://localhost:8545`));

// Global Account Accessors
  var acct1 = web3.eth.accounts[0];

> acct1
undefined

As you can see the value acct1 is empty, when I go back to my tmux session running testrpc, I cannont see the eth_account command which should have been executed.

If I run netstat -tuplen I can indeed see that testrpc is running on port 8545:

tcp6       0      0 :::8545                 :::*                    LISTEN      1000       3431613     50196/node

It looks like there were many changes made in web3 so to now access the accounts you need to use the following:

web3.eth.personal.getAccounts().then(res => console.log(res)) to list all accounts ..... or web3.eth.personal.getAccounts().then(res => console.log(res[0])) to display account[0] etc
