Hi People, can anyone know how to connect the web3 code to private Ethereum

What are you using, if web3 than use web3's http provider, if truffle than change truffle config files to point to your nodes

I am asking after deployment of smart using truffle

I want to call the smart contract functionality from web3

Change the truffle config files to point to your node

I already changed the truffle config and deployed in the private Ethereum

Then how to call the smart contract functionality
