It also gives you a lot of **responsibility**. You have to make sure that the data you return is correct, in the correct format, that it can be serialized, etc.

## Using the `jsonable_encoder` in a `Response` { #using-the-jsonable-encoder-in-a-response }

Because **FastAPI** doesn't make any changes to a `Response` you return, you have to make sure its contents are ready for it.

		// then we need to make sure we have unlocked
		// upto tolerance+1 - especially for RUnlock
		// to ensure that we don't end up with active
		// read locks on the resource after unlocking
		// only half of the lockers.
		return unlocksFailed >= tolerance
	}
	return unlocksFailed > tolerance
}

// checkQuorumLocked determines whether we have locked the required quorum of underlying locks or not

## Configuring Site Replication

- Configure an alias in `mc` for each of the sites. For example if you have three MinIO sites, you may run:

```sh

    AtomicBoolean setUpRan = new AtomicBoolean();
    Runnable setUp =
        () ->
            assertFalse("previous tearDown should have run before setUp", setUpRan.getAndSet(true));
    Runnable tearDown = () -> assertTrue("setUp should have run", setUpRan.getAndSet(false));
    return MapTestSuiteBuilder.using(new CheckSetUpHashMapGenerator(setUpRan))
        .named("setUpTearDown")
        .withFeatures(

    tests, either. This causes it to fail to find AtomicLongMapTest.

    Our workaround is to tell GWT that util.concurrent and all other packages
    have prod supersource, even if they have none. GWT is happy to ignore us
    when we specify a nonexistent path.

    (I hope that this workaround does not cause its own problems in the future.)

In your production system, you probably have a frontend created with a modern framework like React, Vue.js or Angular.

And to communicate using WebSockets with your backend you would probably use your frontend's utilities.

Or you might have a native mobile application that communicates with your WebSocket backend directly, in native code.

Or you might have any other way to communicate with the WebSocket endpoint.
