How to use the apollo-server-hapi.ApolloServer function in apollo-server-hapi

'use strict';

const { ApolloServer } = require('apollo-server-hapi')
const resolvers = require('./resolvers')
const typeDefs = require('./defs')

/**
 * Schema used by the Apollo GraphQL plugin for the hapi.js server.
 */
module.exports = new ApolloServer({
  typeDefs,
  resolvers
})

import { ApolloServer } from "apollo-server-hapi";
import { typeDefs } from "./defs";
import { resolvers } from "./resolvers";

/**
 * Schema used by the Apollo GraphQL plugin for the hapi.js server.
 */
export const apolloServer = new ApolloServer({
    typeDefs,
    resolvers,
});

//This should be in the config
            port: 8087
        }
    )

    const schema = makeExecutableSchema(
        {
            typeDefs,
            resolvers,
            resolverValidationOptions: {
                requireResolversForResolveType: false
            }
        }
    )

    const apolloServer = new ApolloServer(
        {
            schema,
            context: {
                db: prisma
            }
        }
    )

    await apolloServer.applyMiddleware({
        app: api
    })

    await apolloServer.installSubscriptionHandlers(api.listener)

    return api
 }
