-# Backend API (V2) Documentation
+# Backend API docs
 
-This document describes the current backend API routes and their real response shapes, based on the code in `backendV2`.
+If you want to cooperate with me, or build something new with my backend API, feel free to reach out!
 
----
+On this page you will learn how my API works.
 
-## Base URLs
+## General information
 
-- Frontend: `https://insta.the1s.de`
+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.
-- Backend: `https://backend.insta.the1s.de`
-- Base path: `https://backend.insta.the1s.de/api`
 
-Service status: `https://status.the1s.de`
+**\*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 **protected** endpoints require an API key as a path parameter `:key`.
+All endpoints require the Admin API key (`ADMIN_ID`) as a URL parameter.
 
-Rules for `:key`:
+Example: `/apiV2/items/{ADMIN_ID}`
-
-- Exactly 8 characters  
-- Digits only (`^[0-9]{8}$`)
-
-Example:
-
-```http
-GET /api/items/12345678
-```
-
-On missing / invalid key:
-
-- Status: `401 Unauthorized`
-- Body (exact message depends on `authenticate` in `backendV2/services/authentication.js`)
-
-Auth-related modules:
-
-- `backendV2/services/authentication.js`
-- `backendV2/services/database.js`
-
-Route handlers:
-
-- `backendV2/routes/api/api.route.js`
-- `backendV2/routes/api/api.database.js`

-#### Error response
+Each item has the following properties:
 
-```json
+- `id`: The unique identifier for the item.
-{ "message": "Failed to fetch items" }
+- `item_name`: The name of the item.
-```
+- `can_borrow_role`: The role ID that is allowed to borrow the item.
+- `inSafe`: Indicates whether the item is currently in the locker (1) or not (0). This variable/state can change over time.
 
-#### Status codes
+_You also get an http 200 status code._
-
-- `200 OK` – success, `data` is an array (possibly empty)
-- `401 Unauthorized` – invalid / missing key
-- `500 Internal Server Error` – database error or `success: false` from DB layer

-### 2.2 Toggle item safe state
+### 2. Change Item Safe State
 
-**POST** `/api/change-state/:key/:itemId/:state`
+**POST** `/apiV2/controlInSafe/:key/:itemId/:state`
 
-> You do not need this endpoint to set the states of the items when the items are taken out or returned. When you take or return a loan, the item states are set automatically by the loan endpoints. This endpoint is only for manually toggling the `inSafe` state of an item.
+Updates the `inSafe` state of an item (whether it is in the locker).
 
-Path parameters:
+- `state` must be `"1"` (in safe) or `"0"` (not in safe).
 
-- `:key` – API key (8 digits)
+#### Example Request
-- `:itemId` – numeric `id` of the item
-- `:state` – must be `"1"` or `"0"`
 
-Handler in `api.route.js` calls `changeInSafeStateV2(itemId)`, which executes:
+```
-
+POST https://backend.insta.the1s.de/apiV2/controlInSafe/your_admin_key/item_id/new_item_state
-```sql
-UPDATE items SET inSafe = NOT inSafe WHERE id = ?
 ```
 
-#### Example request
+#### Example Response
 
-```http
+```
-POST https://backend.insta.the1s.de/api/change-state/12345678/42/1
+{}
 ```
 
-(Will toggle `inSafe` for item `42`, regardless of the final `1`.)
+_An empty object means, that the operation was successful and no further information is returned._
 
-#### Successful response (current implementation)
+_You also get an http 200 status code._
-
-```json
-{
-  "data": null
-}
-```
-
-#### Error responses
-
-Invalid `state` (anything other than `"0"` or `"1"`):
-
-```json
-{ "message": "Invalid state value" }
-```
-
-Failed update:
-
-```json
-{ "message": "Failed to update item state" }
-```
-
-#### Status codes
-
-- `200 OK` – item state toggled
-- `400 Bad Request` – invalid `state` parameter
-- `401 Unauthorized` – invalid / missing key
-- `500 Internal Server Error` – database/update failure or `success: false` from DB layer

-# 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.

-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)

-- Docs: [docs/](docs)
-  - API docs (see below): [docs/backend_API_docs/README.md](docs/backend_API_docs/README.md)
-
-## 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
-
-- Scripts: see [frontend/package.json](frontend/package.json) and [backend/package.json](backend/package.json)
-  - Frontend: `npm run dev`, `npm run build`, `npm run preview`, `npm run lint`
-  - Backend: `npm start`
-- Linting: ESLint configured via [frontend/eslint.config.js](frontend/eslint.config.js)
-- TypeScript configs: [frontend/tsconfig.app.json](frontend/tsconfig.app.json), [frontend/tsconfig.node.json](frontend/tsconfig.node.json)
-
-## 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).

-# 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.
