**FastAPI** has optional support for GraphQL (provided by Starlette directly), using the `graphene` library.

You can combine normal FastAPI path operations with GraphQL on the same application.

## Import and use `graphene`

GraphQL is implemented with Graphene, you can check <a href="https://docs.graphene-python.org/en/latest/quickstart/" target="_blank">Graphene's docs</a> for more details.

Import `graphene` and define your GraphQL data:

```Python hl_lines="1 6 7 8 9 10"
{!./src/graphql/tutorial001.py!}
```

## Add Starlette's `GraphQLApp`

Then import and add Starlette's `GraphQLApp`:

```Python hl_lines="3 14"
{!./src/graphql/tutorial001.py!}
```

!!! info
    Here we are using `.add_route`, that is the way to add a route in Starlette (inherited by FastAPI) without declaring the specific operation (as would be with `.get()`, `.post()`, etc).

## Check it

Run it with Uvicorn and open your browser at <a href="http://127.0.0.1:8000" target="_blank">http://127.0.0.1:8000</a>.

You will see GraphiQL web user interface:
