How can structure apollo-server?

Question

I would like to handle all entity-related things in the entity file. What do I mean by that?

Let's say I have two entities called User and Post

I would like to do all kinds of stuff like type, query and resolver for User inside the user.ts file.

Similarly, Post related things should be in post.ts.

I have a problem with typeDefs and resolver in the main file, in this case index.ts

Is there any example to handle that?

My intention is

src
├── schema
│   ├── user
│   │   │    index.js(it has its own resolver, types,queries, and mutations)
│   ├── order
│   │   └── index.js((it has its own resolver, types,queries, and mutations))
│   └── index.js
└── app.js
