Ha egy olyan CLI alkalmazást fejlesztesz amit a parancssorban kell használni webes API helyett, tekintsd meg: <a href="https://typer.tiangolo.com/" class="external-link" target="_blank">**Typer**</a>.

**Typer** a FastAPI kistestvére. A **CLI-k FastAPI-ja**. ⌨️ 🚀

# Dependencies with yield { #dependencies-with-yield }

FastAPI supports dependencies that do some <abbr title='sometimes also called "exit code", "cleanup code", "teardown code", "closing code", "context manager exit code", etc.'>extra steps after finishing</abbr>.

To do this, use `yield` instead of `return`, and write the extra steps (code) after.

/// tip

Make sure to use `yield` one single time per dependency.

- HPA controller will no longer emit a 'FailedRescale' event if a scale operation initially fails due to a conflict but succeeds after a retry; a 'SuccessfulRescale' event will be emitted instead. A 'FailedRescale' event is still emitted if retries are exhausted. ([#132007](https://g...

It is **HIGHLY encouraged** that you write or copy the code, edit it and run it locally.

Using it in your editor is what really shows you the benefits of FastAPI, seeing how little code you have to write, all the type checks, autocompletion, etc.

* `tax: float = 10.5` has a default of `10.5`.
* `tags: List[str] = []` has a default of an empty list: `[]`.

but you might want to omit them from the result if they were not actually stored.

For example, if you have models with many optional attributes in a NoSQL database, but you don't want to send very long JSON responses full of default values.
