# Ticketsystem
A ticket system with backend and frontend components.
## Components
- **[Backend]** - The server-side API and business logic
- **[Frontend]** - 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:
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:
`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;
> }
> ```

## Usage of AI
Github Copilot CLI was used with the model Claude Haiku 4.5 to generate most of the documentation:
### Prompt
Generate comments for cargo doc describing the indivilual components and create links to relevant structs, functions etc.
### Output
The comments with `///` or `//!`
I've gone over most of it and modified it to my needs and opinions
