# 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.

!!! note "Technical Details"
    Any function that is valid to use with:

	  Variables are described below.
	- The name of a field of the data, which must be a struct, preceded
	  by a period, such as
		.Field
	  The result is the value of the field. Field invocations may be
	  chained:
	    .Field1.Field2
	  Fields can also be evaluated on variables, including chaining:
	    $x.Field1.Field2
	- The name of a key of the data, which must be a map, preceded

            "class OnField { @B(A.class) String foo; }",
            "class OnParameter { void foo(@B(A.class) int x) {} }"
        outputs.snapshot { run language.compileTaskName }

        when:
        a.text += "/* change */"
        run language.compileTaskName

        then:
        outputs.recompiledClasses("A", "OnClass", "OnMethod", "OnParameter", "OnField")
    }

# Abhängigkeiten mit yield

FastAPI unterstützt Abhängigkeiten, die nach Abschluss einige <abbr title="Manchmal auch genannt „Exit Code“, „Cleanup Code“, „Teardown Code“, „Closing Code“, „Kontext Manager Exit Code“, usw.">zusätzliche Schritte ausführen</abbr>.

Verwenden Sie dazu `yield` statt `return` und schreiben Sie die zusätzlichen Schritte / den zusätzlichen Code danach.

!!! tip "Tipp"
    Stellen Sie sicher, dass Sie `yield` nur einmal pro Abhängigkeit verwenden.
