File-based Routing

Hey @hagopj13!

What do you think about using [`express-file-routing`](https://github.com/matthiaaas/express-file-routing) in this project? It makes the job of creating new routes way cleaner and less time consuming.

#### Directory Structure

Files inside your `/routes` directory will get matched an url path automatically.

```php
├── app.js
├── routes/v1
├── index.ts // index routes
├── posts
├── index.ts
└── :id.ts // dynamic params
└── users.ts
└── package.json
```

- `/routes/v1/index.ts` → /v1
- `/routes/v1/posts/index.ts` → /v1/posts
- `/routes/v1/posts/:id.ts` → /v1/posts/:id
- `/routes/v1/users.ts` → /v1/users

Review app.js, the /routes directory structure, and package.json alongside the proposed express-file-routing package. Determine whether the routing convention fits this boilerplate and define the expected route mappings before considering adoption.
