 ## Authentication
 
-All endpoints require the Admin API key (`ADMIN_ID`) as a URL parameter.
+All endpoints require an API key as a path parameter named `:key`.
 
-Example: `/apiV2/items/{ADMIN_ID}`
+Example: `/apiV2/items/:key`

+If the key is missing or invalid, the API responds with `401 Unauthorized`.

+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
-
-- 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).

+# 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,
