What are some file structure best practices for apollo server?

import http from "http"; import express from "express"; import { ApolloServer } from "apollo-server-express"; import { makeExecutableSchema } from "graphql-tools"; import { mergeResolvers, mergeTypes } from "merge-graphql-schemas"; import path from "path"; import glob from "glob"; import fs from "fs"; (async () => { // TypeDefs const typeDefs = glob .sync(path.join(__dirname, "./**/*.graphql")) .map(f => fs.readFileSync(f, { encoding: "utf8" })); // Resolvers const resolvers = await Promise.all( glob .sync(path.join(__dirname, "./**/*.resolver.ts")) .map(async f => (await import(f)).resolver) ); // Mocks const mocks = await Promise.all( glob .sync(path.join(__dirname, "./**/*.mock.ts")) .map(async f => (await import(f)).mock) ); const schema = makeExecutableSchema({ resolvers: mergeResolvers(resolvers), resolverValidationOptions: { requireResolversForResolveType: false }, typeDefs: mergeTypes(typeDefs) }); const PORT = 4000; const app = express(); const server = new ApolloServer({ mocks: Object.assign({}, ...mocks), schema }); server.applyMiddleware({ app }); const httpServer = http.createServer(app); server.installSubscriptionHandlers(httpServer); httpServer.listen(PORT, () => { console.log( `🚀 Server ready at http://localhost:${PORT}${server.graphqlPath}` ); console.log( `🚀 Subscriptions ready at ws://localhost:${PORT}${ server.subscriptionsPath }` ); }); })();
