# datatrash
|
||||
|
||||
A file and text uploading service with configurable time limit
|
||||
|
||||
![Application screenshot](./screenshot.png)
|
||||
|
||||
## compiling
|
||||
|
||||
Compiling is a little strange.
|
||||
The SQL-statements are checked for correctness at compile-time, unfortunately this means that the
|
||||
database needs to be running at compile-time too.
|
||||
|
||||
To get set up:
|
||||
|
||||
- Start a postgresql somewhere
|
||||
- Set its connection url in the `.env` file
|
||||
- Run the `init-db.sql` script in the database (`cat init-db.sql | psql`)
|
||||
- Build the project `cargo build --release`
|
||||
|
||||
## running & config
|
||||
|
||||
At runtime the environment variable `DATABASE_URL` must be set (e.g. `postgres://localhost`).
|
||||
A folder named `files` needs to be created next to the application.
|
||||
|
||||
Other things are not configurable yet.
|
||||
|
||||
- The application listens on port 8000
|
||||
- The server url is `http://localhost:8000/`
|
||||
- The upload limit is 8MiB
|
||||
- The maximum filename length is 255
|
||||
- The uploaded files are stored in the `files` directory
