 # Ticketsystem
 A ticket system with backend and frontend components.
 ## Components
 - **[Backend](../backend/index.html)** - The server-side API and business logic
 - **[Frontend](../frontend/index.html)** - The client-side user interface
 ## Usage
 ### Prerequisite
 #### IMPORTANT
 Before compiling the programm you have to install the rust toolchain. 
 For a guide to do this, visit: <https://rust-lang.org/tools/install/>
 A instance of a postgresql has to be accessible to the backend. Place the connection details in a .env file into the variable `DATABASE_URL`
 To setup the tables you either can create them manually by following the sheme specified in `backend/migrations` or apply them with sqlx
 To install sqlx run `cargo install sqlx` and then in the `backend` directory run `sqlx migrate run` to create the tables
 ### Environment
 The .env file has to be in the root directory of the project or in the same directory as the executable
 Keys:
 `DATABASE_URL`: Specifying the url and connection details for the database
 `TOKEN_SECRET`: The JWT token secret, can theoretically be anything but is more secure when generated with a tool, e.g: <https://jwtsecrets.com/>
 `ORIGIN`: The origin of the frontend, used for CORS rules
 `BACKEND_PORT`: The port which the backend should use to run on
 ### Backend
 The backend can either be run via `cargo run --release` or `cargo build --release` using the correct target architecture, e.g. 'x86_64-unknown-linux-gnu', 
 the executable will be placed in the `target/release` directory and can then be run via any method
 ### Frontend
 The HTML code for the frontend can be generated by using `trunk build`. The resulting files will end up in the `frontend/dist` directory and can be served over any webserver supporting wasm
 #### NOTE
 To install trunk run `cargo install trunk`
 #### IMPORTANT
 Requests from the frontend to /api/* have to be proxied to the Backend
 Example with nginx and frontend running at localhost:8000 and backend at localhost:9000 :
 ```nginx
 location /api/ {
  proxy_pass http://localhost:9000/api;
 }
 ```

 Github Copilot CLI was used with the model Claude Haiku 4.5 to generate most of the documentation
 Google Antigravity generated the Sequence Diagrams
 ### Prompt 
 Generate comments for cargo doc describing the indivilual components and create links to relevant structs, functions etc.
 Generate a sequence diagramm in @[README.md] behind the class diagramms
