By default, if there is a `config.json` file in the current directory of the `cc-backend` process, it will be loaded even without the `--config` flag.
You find documentation of all supported configuration and command line options [here](./configs.README.md).
## Database initialization and migration
Every cc-backend version supports a specific database version.
On startup the version of the sqlite database is validated and cc-backend will terminate if the version does not match.
cc-backend supports to migrate the database schema up to the required version using the `--migrate-db` command line option.
In case the database file does not yet exist it is created and initialized by the `--migrate-db` command line option.
In case you want to use a newer database version with an olden version of cc-backend you can downgrade a database using the external [migrate](https://github.com/golang-migrate/migrate) tool.
In this case you have to provide the path to the migration files in a recent source tree: `./internal/repository/migrations/`.
## Development
In case the REST or GraphQL API is changed the according code generators have to be used.
