The code is simple : stay infura utilize ropsten Test network sol:

pragma solidity ^0.5.0;contract MyContract {    string value;    constructor() public {        value = "myValue";    }    function get() public view returns(string memory ) {        return value;    }    function set(string memory _value) public {        value = _value;    }}

js:

const Web3 = require('web3')const web3 = new Web3('https://ropsten.infura.io/v3/MY_INFURA_API_KEY')const contractAddress = '0x30951343d6d80d2c94897f1a81c53cc030aef879'const contractABI = ```[    {        "constant": false,        "inputs": [            {                "internalType": "string",                "name": "_value",                "type": "string"            }        ],        "name": "set",        "outputs": [],        "payable": false,        "stateMutability": "nonpayable",        "type": "function"    },    {        "constant": true,        "inputs": [],        "name": "get",        "outputs": [            {                "internalType": "string",                "name": "",                "type": "string"            }        ],        "payable": false,        "stateMutability": "view",        "type": "function"    },    {        "inputs": [],        "payable": false,        "stateMutability": "nonpayable",        "type": "constructor"    }]const contract = new web3.eth.Contract(contractABI, contractAddress)contract.methods.get().call((err, val) => {  console.log({ err, val })})
