resolvers.js

    const NiceDataLoader = require('nicedataloader').NiceDataLoader;
    const pricesLoader = new NiceDataLoader(productResolver.getPrices);
    
    const resolvers = {
        Query: {
            Products: (obj, args, context, info) 
                    => productResolver.getProducts( args, context, info),
        },
        Products: {
            Prices: (parent, args, context, info) 
                        => pricesLoader.get(parent.id, args, context, info),
        .
        .
        .

        const mysqlPool = context.mysqlPool;
        const customerType = args.customerType;
        return new Promise((resolve, reject) => {
            productModel.getPrices(mysqlPool, keys, customerType).then((result) => {
            resolve(result);
        }).catch((error) => {
            reject(error);
        });
    };
