Use bitcoincashjs Library

const bitcore = require('bitcoincashjs');

const HdPublicKey = new bitcore.HDPublicKey.fromString(xpubKey);
            const derivedPublicKey = HdPublicKey.derive("m/0/" + index).publicKey;
            const address = derivedPublicKey.toAddress();
            requestObj.BCHAddress = address.toString();

to verify Transaction use blocktrail-sdk

const blocktrail = require('blocktrail-sdk');
const client = blocktrail.BlocktrailSDK({
    apiKey: apiKey,
    apiSecret: apiSecret,
    network: "BCC",
    testnet: false
});

then you can call many function of client like

    client.addressTransactions(bitAddress[i].BCHAddress,
     async function (err, addressTxs) {
         //Code here 
    });
