We will create a FastAPI **dependency** with `yield` that will provide a new `Session` for each request. This is what ensures that we use a single session per request. 🤓

Then we create an `Annotated` dependency `SessionDep` to simplify the rest of the code that will use this dependency.

### Create Database Tables on Startup

The important thing to remember is that **the first *type parameter*** you pass to `Annotated` is the **actual type**. The rest, is just metadata for other tools.

For now, you just need to know that `Annotated` exists, and that it's standard Python. 😎

Later you will see how **powerful** it can be.

3. Kopiere die Datei mit den Paketanforderungen in das Verzeichnis `/code`.

    Kopieren Sie zuerst **nur** die Datei mit den Anforderungen, nicht den Rest des Codes.

    Da sich diese Datei **nicht oft ändert**, erkennt Docker das und verwendet den **Cache** für diesen Schritt, wodurch der Cache auch für den nächsten Schritt aktiviert wird.

    val open: Boolean
    val cancel: Boolean
    this.withLock {
      cancel = !source.finished && source.closed && (sink.finished || sink.closed)
      open = isOpen
    }
    if (cancel) {
      // RST this stream to prevent additional data from being sent. This is safe because the input
      // stream is closed (we won't use any further bytes) and the output stream is either finished

Het belangrijkste om te onthouden is dat **de eerste *typeparameter*** die je doorgeeft aan `Annotated` het **werkelijke type** is. De rest is gewoon metadata voor andere hulpmiddelen.

Voor nu hoef je alleen te weten dat `Annotated` bestaat en dat het standaard Python is. 😎

Later zul je zien hoe **krachtig** het kan zijn.

/// tip

          // Don't include the (unused) separator in next split string.
          nextStart = offset;
          continue;
        }

        if (limit == 1) {
          // The limit has been reached, return the rest of the string as the
          // final item. This is tested after empty string removal so that
          // empty strings do not count towards the limit.
          end = toSplit.length();
          offset = -1;
