### Import `FastAPI` { #import-fastapi }

You import and create a `FastAPI` class as normally.

And we can even declare [global dependencies](dependencies/global-dependencies.md) that will be combined with the dependencies for each `APIRouter`:

{* ../../docs_src/bigger_applications/app_an_py310/main.py hl[1,3,7] title["app/main.py"] *}

        if (crudMode != expectedMode) {
            throwValidationError(messages -> {
                messages.addErrorsCrudInvalidMode(GLOBAL, String.valueOf(expectedMode), String.valueOf(crudMode));
            }, errorHook);
        }
    }

    /**
     * Encodes permission strings into an array.
     *

	input       chan *queueItem           // input for workers
	queue       chan *queueItem           // output from workers in order
	err         error                     // global error state, only touched by Reader.Read
	bufferPool  bpool.Pool[[]byte]        // pool of []byte objects for input
	kvDstPool   bpool.Pool[[]jstream.KVS] // pool of []jstream.KVS used for output

        if (port <= 0) {
            port = SmbConstants.DEFAULT_PORT;
        }

        // Perform cleanup and health checks without global synchronization
        cleanup();
        performHealthCheck();

        if (log.isTraceEnabled()) {
            log.trace("Exclusive " + nonPooled + " enforced signing " + forceSigning);
        }

Doing that in separated functions that don't share logic or variables together is more difficult as you would need to store values in global variables or similar tricks.

Because of that, it's now recommended to instead use the `lifespan` as explained above.
