So, the frontend (that runs in the browser) would try to reach `/openapi.json` and wouldn't be able to get the OpenAPI schema.

Because we have a proxy with a path prefix of `/api/v1` for our app, the frontend needs to fetch the OpenAPI schema at `/api/v1/openapi.json`.

* Automatische Dokumentation der Datenmodelle mit <a href="https://json-schema.org/" class="external-link" target="_blank"><strong>JSON Schema</strong></a> (da OpenAPI selbst auf JSON Schema basiert).
* Um diese Standards herum entworfen, nach sorgfältigem Studium. Statt einer nachträglichen Schicht darüber.

* Automatyczna dokumentacja modelu danych za pomocą <a href="https://json-schema.org/" class="external-link" target="_blank"><strong>JSON Schema</strong></a> (ponieważ OpenAPI bazuje na JSON Schema).
* Zaprojektowane z myślą o zgodności z powyższymi standardami zamiast dodawania ich obsługi po fakcie.
* Możliwość automatycznego **generowania kodu klienta** w wielu językach.
