Truffle Smart Contract Loader For Server Side:

Use case: You want to use the generate truffle build/contracts abi definitions to call SmartContracts from a Server:

Example:

CONSTRUCTOR VARIABLES:

CONTRACTS_PATH="<PATH TO TRUFFLE PROJECT>/build/contracts"
PRIVATE_KEY=""
BLOCKCHAIN_URL="http://localhost:7545"
NETWORK_ID=5777

CODE:

const CAMPAIGN_LOAD_ABIS = new Set([
    "CampaignTrust",
    "PollingBooth",
    "DistributionFactory",
    "CampaignRegistry",
    "CampaignManager",
    "KingTokenERC667",
    "TestContract",
    "RealMath"
]);

let contractManager = new ContractManager(process.env.CONTRACTS_PATH, process.env.PRIVATE_KEY, process.env.BLOCKCHAIN_URL, process.env.NETWORK_ID);
let instances = contractManager.getContractsInstances(CAMPAIGN_LOAD_ABIS);

//Invoke SmartContract
let userAddress = (await contractManager.getWallet()).address
console.log("Invoking KingTokenERC667 SmartContract To Get User Balance:")
console.log(`User Balance For ${userAddress} is`, parseInt(await instances.KingTokenERC667.balanceOf(userAddress)));
