 `app/data.server.ts` implements the `db` object which mimics an ORM in the style of [Prisma](https://www.prisma.io/). The method `db.user#findMany` logs _user#findMany_ to the console, for demo purposes.
 
-There's exactly one DataLoader factory `createUsersByIdLoader`, implemented in `app/loaders/userLoader.ts`. It's put on context of [createRequestHandler](https://remix.run/other-api/adapter#createrequesthandler) in `server/index.ts` as `usersById` which is made available to all Remix-loaders and -actions. Both the loaders of `app/routes/users.tsx` and `app/routes/users/_index.tsx` make calls to this loader. When inspecting the server logs while refreshing the page, you'll notice that there's only one log _user#findMany_ per request, proving that with this implementation, there's only one rountrip to the database.
