## Overview

This repository is a small Express API starter. A client sends requests to the server, which dispatches user requests to resource routes; those routes validate or retrieve user data through the in-memory store and return JSON responses. A separate health endpoint reports liveness. The README documents these capabilities, and the sampled source confirms their wiring. The user data store is in-memory and resets on server restart; no persistent database or external service is shown.

Main entry points: [`server.js`](https://github.com/mate-academy/claude-set-up-claude-on-a-project/blob/main/server.js) (Express server), [`routes/users.js`](https://github.com/mate-academy/claude-set-up-claude-on-a-project/blob/main/routes/users.js) (User routes), [`routes/health.js`](https://github.com/mate-academy/claude-set-up-claude-on-a-project/blob/main/routes/health.js) (Health route), [`db/store.js`](https://github.com/mate-academy/claude-set-up-claude-on-a-project/blob/main/db/store.js) (Memory store)

## Components

### API entry

- [Express server](https://github.com/mate-academy/claude-set-up-claude-on-a-project/blob/main/server.js): `server.js`

### API routes

- [User routes](https://github.com/mate-academy/claude-set-up-claude-on-a-project/blob/main/routes/users.js): `routes/users.js`
- [Health route](https://github.com/mate-academy/claude-set-up-claude-on-a-project/blob/main/routes/health.js): `routes/health.js`

### User state

- [Memory store](https://github.com/mate-academy/claude-set-up-claude-on-a-project/blob/main/db/store.js): `db/store.js`

### Other components

- **API client**
