# Return a Response Directly { #return-a-response-directly }

When you create a **FastAPI** *path operation* you can normally return any data from it: a `dict`, a `list`, a Pydantic model, a database model, etc.

By default, **FastAPI** would automatically convert that return value to JSON using the `jsonable_encoder` explained in [JSON Compatible Encoder](../tutorial/encoder.md){.internal-link target=_blank}.

	minioClient, err := minio.New(stsEndpointURL.Host, opts)
	if err != nil {
		log.Fatalf("Error initializing client: %v", err)
	}

	// Use minIO Client object normally like the regular client.
	if bucketToList == "" {
		bucketToList = minioUsername
	}
	fmt.Printf("Calling list objects on bucket named `%s` with temp creds:\n===\n", bucketToList)

# Security { #security }

There are many ways to handle security, authentication and authorization.

And it normally is a complex and "difficult" topic.

In many frameworks and systems just handling security and authentication takes a big amount of effort and code (in many cases it can be 50% or more of all the code written).

		Secure: stsEndpointURL.Scheme == "https",
	}
	minioClient, err := minio.New(stsEndpointURL.Host, copts)
	if err != nil {
		log.Fatalf("Error initializing client: ", err)
	}

	// Use minIO Client object normally like the regular client.
	fmt.Printf("Calling list objects on bucket named `%s` with temp creds:\n===\n", bucketToList)
	objCh := minioClient.ListObjects(context.Background(), bucketToList, minio.ListObjectsOptions{})

error message, but this package reserves the right to not force a fault on
freed memory. That means a valid implementation of this package is to just
allocate all memory the way the runtime normally would, and in fact, it
reserves the right to occasionally do so for some Go values.

## Create a Project { #create-a-project }

First, create a directory for your project.

What I normally do is that I create a directory named `code` inside my home/user directory.

And inside of that I create one directory per project.

<div class="termy">

```console
// Go to the home directory
$ cd

# from the current origin/master.
# copy and edit the 'go run' command by hand to use a different branch.
v%.zip:
	git fetch origin master
	go run ../../src/cmd/go/internal/fips140/mkzip.go v$*

# normally mkzip refuses to overwrite an existing zip file.
# make v1.2.3.rm removes the zip file and and unpacked
# copy from the module cache.
v%.rm:
	rm -f v$*.zip

You can use the same dependency *functions* you use normally.

### Dependency requirements { #dependency-requirements }

They can declare request requirements (like headers) or other sub-dependencies:

{* ../../docs_src/dependencies/tutorial006_an_py39.py hl[8,13] *}

### Raise exceptions { #raise-exceptions }

These dependencies can `raise` exceptions, the same as normal dependencies:

When referring to the remote machine, it's common to call it **server**, but also **machine**, **VM** (virtual machine), **node**. Those all refer to some type of remote machine, normally running Linux, where you run programs.

## Install the Server Program { #install-the-server-program }

When you install FastAPI, it comes with a production server, Uvicorn, and you can start it with the `fastapi run` command.

### Normal **FastAPI** { #normal-fastapi }

First, write all your **FastAPI** application as normally:

{* ../../docs_src/extending_openapi/tutorial001.py hl[1,4,7:9] *}

### Generate the OpenAPI schema { #generate-the-openapi-schema }
