## Overview

This is a small Express badminton-court booking API with booking creation, listing, conflict checks, deletion, and health endpoints. The nested `badminton-booking-api/server.js` is the more complete implementation: it reads and writes `db.json` and includes an in-memory fallback. The tree contains a second, divergent root-level server; this graph describes the nested implementation. The HTML is present, but its contents were not sampled, so its interaction with the API is not inferred.

Main entry points: [`badminton-booking-api/server.js`](https://github.com/chutikan489622-star/api_681310006/blob/main/badminton-booking-api/server.js) (Booking storage), [`badminton-booking-api/db.json`](https://github.com/chutikan489622-star/api_681310006/blob/main/badminton-booking-api/db.json) (JSON file)
