    By default SQLite will only allow one thread to communicate with it, assuming that each thread would handle an independent request.

    This is to prevent accidentally sharing the same connection for different things (for different requests).

# CORS (Cross-Origin Resource Sharing)

<a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS" class="external-link" target="_blank">CORS or "Cross-Origin Resource Sharing"</a> refers to the situations when a frontend running in a browser has JavaScript code that communicates with a backend, and the backend is in a different "origin" than the frontend.

## Origin

    Using the cache in this step will **save** you a lot of **time** when building the image again and again during development, instead of **downloading and installing** all the dependencies **every time**.

5. Copy the `./app` directory inside the `/code` directory.

Uvicorn est un serveur ASGI rapide comme l'éclair, basé sur uvloop et httptools.

Il ne s'agit pas d'un framework web, mais d'un serveur. Par exemple, il ne fournit pas d'outils pour le routing. C'est
quelque chose qu'un framework comme Starlette (ou **FastAPI**) fournirait par-dessus.

C'est le serveur recommandé pour Starlette et **FastAPI**.
