## Reduce duplication { #reduce-duplication }

Reducing code duplication is one of the core ideas in **FastAPI**.

As code duplication increments the chances of bugs, security issues, code desynchronization issues (when you update in one place but not in the others), etc.

        api(subproject)
      }
    }
    api("com.squareup.okhttp3:okhttp-jvm:${project.version}")
    api("com.squareup.okhttp3:okhttp-android:${project.version}")
  }
}

publishing {
  publications.create<MavenPublication>("maven") {
    from(project.components["javaPlatform"])
  }

    }

    @CanIgnoreReturnValue // Sure, why not?
    @Override
    public T apply(T key) {
      awaitUninterruptibly(delayLatch);
      return key;
    }
  }

  /*
   * TODO(cpovirk): eliminate duplication between these tests and those in LegacyMapMakerTests and
   * anywhere else
   */

  public void testInitialCapacity_negative() {
    MapMaker maker = new MapMaker();

 *     list of available routes.
 *
 * If the pool gains an eligible connection while DNS, TCP, or TLS work is in flight, this finder
 * will prefer pooled connections. Only pooled HTTP/2 connections are used for such de-duplication.
 *
 * It is possible to cancel the finding process by canceling its call.
 *
 * Implementations of this interface are not thread-safe. Each instance is thread-confined to the
 * thread executing the call.
 */

That way I could find the best ways to reduce code duplication as much as possible, to have completion everywhere, type and error checks, etc.

All in a way that provided the best development experience for all the developers.

## Requirements { #requirements }

You just pass it to `Depends` and **FastAPI** knows how to do the rest.

///

## Share `Annotated` dependencies { #share-annotated-dependencies }

In the examples above, you see that there's a tiny bit of **code duplication**.

When you need to use the `common_parameters()` dependency, you have to write the whole parameter with the type annotation and `Depends()`:

```Python
commons: Annotated[dict, Depends(common_parameters)]
```

			if err != nil {
				return err
			}
			nodeBuckets[idx] = localBuckets
			return nil
		}, idx)
	}

	errs := g.Wait()

	// The list of buckets in a map to avoid duplication
	resultMap := make(map[string]BucketInfo)

	for poolIdx := 0; poolIdx < sys.poolsCount; poolIdx++ {
		perPoolErrs := make([]error, 0, len(sys.peerClients))
		for i, client := range sys.peerClients {

///

/// check

The `prefix`, `tags`, `responses`, and `dependencies` parameters are (as in many other cases) just a feature from **FastAPI** to help you avoid code duplication.

///

### Import the dependencies { #import-the-dependencies }

This code lives in the module `app.routers.items`, the file `app/routers/items.py`.
