Please first search existing issues for the feature you are requesting;
it may already exist, even as a closed issue.

Describe the feature.

Please give us as much context as possible about the feature. For example,
you could include a story about a time when you wanted to use the feature,
and also tell us what you had to do instead. The last part is helpful
because it gives us an idea of how much harder your life is without the
feature.

You could **deploy a server** yourself using a combination of tools, you could use a **cloud service** that does part of the work for you, or other possible options.

For example, we, the team behind FastAPI, built [**FastAPI Cloud**](https://fastapicloud.com), to make deploying FastAPI apps to the cloud as streamlined as possible, with the same developer experience of working with FastAPI.

```console
$ pip install "fastapi[standard]"

---> 100%
```

</div>

**Note**: Make sure you put `"fastapi[standard]"` in quotes to ensure it works in all terminals.

## Example { #example }

### Create it { #create-it }

Create a file `main.py` with:

```Python
from fastapi import FastAPI

app = FastAPI()


@app.get("/")
def read_root():

## 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.

For example, you cannot put a Pydantic model in a `JSONResponse` without first converting it to a `dict` with all the data types (like `datetime`, `UUID`, etc) converted to JSON-compatible types.
