-# Backend API docs (apiV2)
+# Borrow System API Documentation
 
-If you want to cooperate with me, or build something new with my backend API, feel free to reach out!
+## Overview
 
-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` 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.
-
----
-
-## 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)_
-
----
+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.
 
 ## Authentication
 
-All endpoints require an API key as a path parameter named `:key`.
-
-Example: `/apiV2/items/:key`
-
-If the key is missing or invalid, the API responds with `401 Unauthorized`.
-
----
+All requests must include a valid API key in the URL path as the `:key` parameter. API keys are 8-digit numeric strings.
 
 ## Endpoints

+**URL Parameters:**
 
-**DO NOT UPDATE THE STATE MANUALLY! (only if the item was taken with an admin key)**
+- **key** - API key
+- **loan_code** - A 6-digit numeric loan code

 ---
 
-### 5) Set take date (now) by loan code
+### Set Return Date
 
-POST `/apiV2/setTakeDate/:key/:loan_code`
+`POST /set-return-date/:key/:loan_code`
 
-Sets the `take_date` to the current server time.
+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.
 
-**Note:** I have updated this API route, so that everytime you return or take a loan, the state of the loaned items is automatically updated.
+**URL Parameters:**
 
-**DO NOT UPDATE THE STATE MANUALLY! (only if the item was taken with an admin key)**
+- **key** - API key
+- **loan_code** - A 6-digit numeric loan code
 
-Example request:
+**Response 200:** Empty JSON object on success.
 
-```
-POST https://backend.insta.the1s.de/apiV2/setTakeDate/12345/123456
+**Response 500:**
+
+```json
+{ "message": "Failed to set return date" }
 ```
 
-Example response:
-
-```
-{ "data": { /* update result */ } }
-```
-
-Status: 200 on success, 500 on failure.
+> **Note:** This endpoint will fail if the loan has already been returned (i.e., `returned_date` is not `NULL`).
 
 ---
 
-## Error handling
+### Open Door
 
-- 401 Unauthorized: Missing or invalid API key
-- 400 Bad Request: Invalid parameters (e.g., wrong state value)
-- 404 Not Found: Loan not found
-- 500 Internal Server Error: Database or server error
+`GET /open-door/:key/:doorKey`
 
----
+Toggles the safe state of an item identified by its door key and returns the associated safe number.
 
-If you have questions or want to collaborate, please reach out!
+**URL Parameters:**
+
+- **key** - API key
+- **doorKey** - The door key identifier assigned to an item
+
+**Response 200:**
+
+```json
+{
+  "data": {
+    "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.

+# 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 [ ]
+```

-# 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,
-      },
-      // other options...

-  - Backend: `npm start`

-- TypeScript configs: [frontend/tsconfig.app.json](frontend/tsconfig.app.json), [frontend/tsconfig.node.json](frontend/tsconfig.node.json)
+- The NAAS (no-as-a-service) and the mysql database are running in a docker container

 ## Configuration notes
