I have deployed a contract using truffle on the testrpc network. I need to write a Javascript code that can connect to the contract and run the functions of the contract but I can't figure out how to do that.


I am now using truffle-contract and truffle-artifactor in order to connect to deployed contracts. Here is the artifactor code :

var Web3 = require('web3');
var fs = require("fs");
var Artifactor = require("truffle-artifactor");
var provider = new Web3.providers.HttpProvider("http://localhost:8545");
var contract = require("truffle-contract");
var temp = require("temp").track();
var path = require("path");
var requireNoCache = require("require-nocache")(module);

var abiVal = JSON.parse(fs.readFileSync('./build/contracts/DINRegistry.json'))

var contractData = {
    contract_name: "DINRegistry",
    abi: abiVal

var dirPath = temp.mkdirSync({
    dir: path.resolve("./"),

var my_path = '/home/lee/Music/DIN-master';
var expected_filepath = path.join(my_path, '/build/contracts/DINRegistry.json')

function artifactCreator() {
    const artifactor = new Artifactor(my_path);

        contract_name: "DINRegistry",
        abi: abiVal
    }, "./DINRegistry.sol.js")


The code isn't able to create the file DINRegistry.sol.js. What is incorrect in this code?

We had this same requirement in one of the project where we interacted with truffle deployed contract from JavaScript. You can check this script for reference - https://github.com/Imaginea/lms/blob/master/server/routes.js

Basically, we are doing following things -

  • define truffle artifacts
  • define web3 http provider, set provider
  • create contract instance with the help of deployed address.

Hope this helps.
