-# Borrow System API Documentation
+# Backend API docs
 
-## Overview
+If you want to cooperate with me, or build something new with my backend API, feel free to reach out!
 
-The Borrow System API provides endpoints for managing items, loans, and door access for a borrowing/locker system. All endpoints require authentication via an 8-digit API key passed as a URL parameter.
+On this page you will learn how my API works.
+
+## General information
+
+When you look at my backend folder and file structure, you can see that I have two files called `API`. The first file called `api.js` is for my web frontend, because this file works together with my JWT token service.
+
+**\*But I have built a second API. You can see the second API file in the same directory, the file is called `apiV2.js`.**
+
+This is the file that you can use to build an API.
+
+But first you have to get the Admin API key, stored in an `.env` file on my server.
+
+---
 
 ## Authentication
 
-All requests must include a valid API key in the URL path as the `:key` parameter. API keys are 8-digit numeric strings.
+All endpoints require the Admin API key (`ADMIN_ID`) as a URL parameter.
 
-## Endpoints
+Example: `/apiV2/items/{ADMIN_ID}`
 
-The Base URL for all endpoints is: `https://insta.the1s.de/backend/api`
+---
 
-### Get All Items
+## URL
 
-`GET /items/:key`
+- The frontend is currently running on `https://insta.the1s.de`.
 
-Returns all items in the system.
+- The backend is currently running on `https://backend.insta.the1s.de`.
 
-**Response 200:**
+You can see the status of this and all my other services at `https://status.the1s.de`.
 
-```json

+
+## Current endpoints
+
+### 1. Get All Items
+
+**GET** `/apiV2/items/:key`
+
+Returns a list of all items and their details.

-
-### Set Take Date
-
-`POST /set-take-date/:key/:loan_code`
-
-Records when items are physically taken by setting `take_date` to the current timestamp. Updates associated items to `in_safe = false` and sets `currently_borrowing` to the loan's username.
-
-**URL Parameters:**
-
-- **key** - API key
-- **loan_code** - A 6-digit numeric loan code
-
-**Response 200:** Empty JSON object on success.
-
-**Response 500:**

-
----
-
-### Set Return Date
-
-`POST /set-return-date/:key/:loan_code`
-
-Marks a loan as returned by setting `returned_date` to the current timestamp. Also updates all associated items to `in_safe = true`, clears `currently_borrowing`, and sets `last_borrowed_person`. Therefore, keep in mind that you must not call other endpoints that will change the safe state of an item after or before calling this endpoint, otherwise the state of the items will be inconsistent.
-
-**URL Parameters:**
-
-- **key** - API key
-- **loan_code** - A 6-digit numeric loan code
-
-**Response 200:** Empty JSON object on success.
-
-**Response 500:**
-
-```json
-{ "message": "Failed to set return date" }
-```
-
-> **Note:** This endpoint will fail if the loan has already been returned (i.e., `returned_date` is not `NULL`).
-
----
-
-### Open Door
-
-`GET /open-door/:key/:doorKey`
-
-Toggles the safe state of an item identified by its door key and returns the associated safe number.
-
-**URL Parameters:**
-
-- **key** - API key
-- **doorKey** - The door key identifier assigned to an item
-
-**Response 200:**
-
-```json
 {
-  "data": {
+  "message": "Loan not found"
-    "safe_nr": 3,
-    "id": 1
-  }
 }
 ```
 
-**Response 500:**
+---
-
-```json
-{ "message": "Failed to open door" }
-```
 
 ## Error Handling
 
-All endpoints return a `500` status code for server-side failures and a JSON body with a `message` field, except for **Get Loan by Code** which returns `404` when no matching loan is found.
+- `403 Forbidden`: Invalid or missing API key.
+- `400 Bad Request`: Invalid parameters (e.g., wrong state value).
+- `500 Internal Server Error`: Database or server error.

-# Docker
-
-## Prerequisites
-
-You have created an empty `docker-compose.override.yml` file in the root directory of this repository.
-
-## Docker Network
-
-If you want to run the stack in a docker network, you need to change the `BACKEND_HOST` variable in the root `.env` file
-to `stockhome-backend`. To add a docker network, create a `docker-compose.override.yml` file in the root directory of
-this repository with the following content:
-
-```yaml
-services:
-  admin-frontend:
-    networks:
-      - proxynet
-
-  backend:
-    networks:
-      - proxynet
-
-  usr-frontend:
-    networks:
-      - proxynet
-
-  no-as-a-service:
-    networks:
-      - proxynet
-
-  mysql:
-    networks:
-      - proxynet
-
-networks:
-  proxynet:
-    external: true
-```
-
-To start off I recommend to set the `BACKEND_HOST` variable to `localhost` and start the stack without a docker network.
-After you have started the stack and everything is working, you can add a docker network.
-
-## Ports
-
-### Change Exposed Ports
-
-If you want to change the exposed ports, you can do this in the `docker-compose.yml` file like so:
-
-```yaml
-services:
-  mysql:
-    ports:
-      - "3306:3306"
-
-  backend:
-    ports:
-      - "8004:8004"
-
-  usr-frontend:
-    ports:
-      - "80:80"
-```
-
-### Remove Exposed Ports
-
-If you want to remove the exposed ports, you can do this in the `docker-compose.override.yml` file like so:
-
-```yaml
-services:
-  mysql:
-    ports: !override [ ]
-
-  backend:
-    ports: !override [ ]
-
-  usr-frontend:
-    ports: !override [ ]
-```

-A small full‑stack system to log in, view available items, reserve them for a time window, and manage personal loans.
+Here you will find the source code of exactly the application that I have hosted.
 
-- Frontend: React + TypeScript + Vite + Tailwind CSS
+The main branch or the branch that I am developing on, is the `dev` branch.
-- Backend: Node.js + Express + MySQL + JWT (jose)
-- Orchestration: Docker Compose (backend + MySQL)

-
-## Features (high‑level)
-
-- Auth via JWT (login -> token cookie) using the backend route in [backend/routes/api.js](backend/routes/api.js).
-- After login, the app loads items, loans, and user loans and keeps them in localStorage.
-- Choose a date range to fetch borrowable items, select items, and create a loan.
-- Manage personal loans list (and delete a loan).
-
-Key frontend utilities:
-
-- [`utils.fetchData.fetchAllData`](frontend/src/utils/fetchData.ts): loads items, loans, and user loans after login.
-- [`utils.fetchData.getBorrowableItems`](frontend/src/utils/fetchData.ts): fetches borrowable items for the selected
-  time range.
-- [`utils.userHandler.createLoan`](frontend/src/utils/userHandler.ts): creates a new loan for selected items.
-- [`utils.userHandler.handleDeleteLoan`](frontend/src/utils/userHandler.ts): deletes a loan and syncs local state.
-- [`utils.toastify.myToast`](frontend/src/utils/toastify.ts): toast notifications.
-
-UI flow (main screens):
-
-- Period selection: [frontend/src/components/Form1.tsx](frontend/src/components/Form1.tsx)
-- Borrowable items + selection: [frontend/src/components/Form2.tsx](frontend/src/components/Form2.tsx)
-- User loans table: [frontend/src/components/Form4.tsx](frontend/src/components/Form4.tsx)
-
-## Development
-
-- The NAAS (no-as-a-service) and the mysql database are running in a docker container
-- `frontend`, `backend` and `admin` are both in a vite dev server and can be started by `npm run dev` in the root
-  directory.
-
-## Configuration notes
-
-- Vite/Tailwind integration via [frontend/vite.config.ts](frontend/vite.config.ts) and `@tailwindcss/vite`; CSS entry
-  uses `@import "tailwindcss"` in [frontend/src/index.css](frontend/src/index.css).
-- Toasts wired in [frontend/src/main.tsx](frontend/src/main.tsx) with `react-toastify`.
-- Local state is stored in `localStorage` keys: `allItems`, `allLoans`, `userLoans`, `borrowableItems`. Cross‑component
-  updates are signaled via window events from [`utils.fetchData`](frontend/src/utils/fetchData.ts).

-# React + TypeScript + Vite
-
-This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
-
-Currently, two official plugins are available:
-
-- [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react) uses [Babel](https://babeljs.io/) for Fast Refresh
-- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react-swc) uses [SWC](https://swc.rs/) for Fast Refresh
-
-## Expanding the ESLint configuration
-
-If you are developing a production application, we recommend updating the configuration to enable type-aware lint rules:
-
-```js
-export default tseslint.config([
-  globalIgnores(['dist']),
-  {
-    files: ['**/*.{ts,tsx}'],
-    extends: [
-      // Other configs...
-
-      // Remove tseslint.configs.recommended and replace with this
-      ...tseslint.configs.recommendedTypeChecked,
-      // Alternatively, use this for stricter rules
-      ...tseslint.configs.strictTypeChecked,
-      // Optionally, add this for stylistic rules
-      ...tseslint.configs.stylisticTypeChecked,
-
-      // Other configs...
-    ],
-    languageOptions: {
-      parserOptions: {
-        project: ['./tsconfig.node.json', './tsconfig.app.json'],
-        tsconfigRootDir: import.meta.dirname,
-      },
-      // other options...
-    },
-  },
-])
-```
-
-You can also install [eslint-plugin-react-x](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-x) and [eslint-plugin-react-dom](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-dom) for React-specific lint rules:
-
-```js
-// eslint.config.js
-import reactX from 'eslint-plugin-react-x'
-import reactDom from 'eslint-plugin-react-dom'
-
-export default tseslint.config([
-  globalIgnores(['dist']),
-  {
-    files: ['**/*.{ts,tsx}'],
-    extends: [
-      // Other configs...
-      // Enable lint rules for React
-      reactX.configs['recommended-typescript'],
-      // Enable lint rules for React DOM
-      reactDom.configs.recommended,
-    ],
-    languageOptions: {
-      parserOptions: {
-        project: ['./tsconfig.node.json', './tsconfig.app.json'],
-        tsconfigRootDir: import.meta.dirname,
-      },
-      // other options...
-    },

-# How to use Atoms
-Atoms are the fundamental building blocks of state management in this system. They represent individual pieces of state that can be shared and manipulated across different components.
-
-You can also name it global state.
-
-## Creating an Atom
-to create an atom you have to declare an atom like this:
-
-```ts
-import { atom } from 'jotai';
-
-export const NAME_OF_YOUR_ATOM = atom<type_of_your_atom>(initial_value);
-```
-
-In this project we declare all atoms in the `States/Atoms.tsx`file. Which you can find above this README file.
-
-## Using an Atom
-To use an atom in your component, you can use the `useAtom` hook provided by Jotai. Here's an example of how to use an atom in a React component:
-
-```tsx
-import { useAtom } from 'jotai';
-import { NAME_OF_YOUR_ATOM } from '@/States/Atoms';
-
-const MyComponent = () => {
-  const [value, setValue] = useAtom(NAME_OF_YOUR_ATOM);
-
-  return (
-    <div>
-      <p>Current value: {value}</p>
-      <button onClick={() => setValue(newValue)}>Update Value</button>
-    </div>
-  );
-};
-```
-
-As you can see, you can use `useAtom` like `useState` but the state is global. In this example `value` is the current state of the atom, and `setValue` is a function to update the state, which is also known as the setter function.
