 ## 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` which 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`.**

-But first you have to get an API Key. You can get the API key from my admin dashboard. When you don't have any access to my admin dashboard, please contact your administrator or me.
+This is the file that you can use to build an API.

-## Base URL
-
- Frontend: `https://insta.the1s.de`
- Backend: `https://backend.insta.the1s.de`
- Base path for this API: `https://backend.insta.the1s.de/apiV2`
-
-You can see the status of this and all my other services at `https://status.the1s.de`.
-
-_I have also build a [fallback page](https://git.the1s.de/theis.gaedigk/fallback-page). When only the application is down, you will see a friendly message and a link to the status page. (Only if the server is not down)_
+But first you have to get the Admin API key, stored in an `.env` file on my server.

 ---

 ## Authentication

-All endpoints require an API key as a path parameter named `:key`.
+All endpoints require the Admin API key (`ADMIN_ID`) as a URL parameter.

-Example: `/apiV2/items/:key`
-
-If the key is missing or invalid, the API responds with `401 Unauthorized`.
+Example: `/apiV2/items/{ADMIN_ID}`

-# 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/) (or [oxc](https://oxc.rs) when used in [rolldown-vite](https://vite.dev/guide/rolldown)) 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
-
-## React Compiler
-
-The React Compiler is not enabled on this template because of its impact on dev & build performances. To add it, see [this documentation](https://react.dev/learn/react-compiler/installation).
-
-## 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 defineConfig([
-  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 defineConfig([
-  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,

-# 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.

+**You have reached the `debian12` branch.**

-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
- Backend: Node.js + Express + MySQL + JWT (jose)
- Orchestration: Docker Compose (backend + MySQL)
-
-## Contents
-
- Frontend: [frontend/](frontend)
-  - Vite/Tailwind config: [frontend/vite.config.ts](frontend/vite.config.ts), [frontend/tailwind.config.js](frontend/tailwind.config.js)

-  - Schema/seed: [backend/scheme.sql](backend/scheme.sql)
- 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).
-
-## API documentation
-
-Refer to the dedicated API docs:
-
-`docs/backend_API_docs/README.md`
+The main branch or the branch that I am developing on, is the `dev` branch.

-# 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.

-# 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.
