## Installation ( Quick Start )

The quick start method provides a server and CLI to get going quickly. Install
with:

```shell
pip install "strawberry-graphql[debug-server]"
```

## Getting Started

Create a file called `app.py` with the following code:

```python
import strawberry


@strawberry.type
class User:
    name: str
    age: int


@strawberry.type
class Query:
    @strawberry.field
    def user(self) -> User:
        return User(name="Patrick", age=100)


schema = strawberry.Schema(query=Query)
```

This will create a GraphQL schema defining a `User` type and a single query
field `user` that will return a hardcoded user.

To run the debug server run the following command:

```shell
strawberry server app
```

Open the debug server by clicking on the following link:
[http://0.0.0.0:8000/graphql](http://0.0.0.0:8000/graphql)

This will open GraphiQL where you can test the API.

### Type-checking

Strawberry comes with a [mypy] plugin that enables statically type-checking your
GraphQL schema. To enable it, add the following lines to your `mypy.ini`
configuration:

```ini
[mypy]
plugins = strawberry.ext.mypy_plugin
```

[mypy]: http://www.mypy-lang.org/

### Django Integration

A Django view is provided for adding a GraphQL endpoint to your application.

1. Add the app to your `INSTALLED_APPS`.

```python
INSTALLED_APPS = [
    ...,  # your other apps
    "strawberry.django",
]
```

2. Add the view to your `urls.py` file.

```python
from strawberry.django.views import GraphQLView
from .schema import schema

urlpatterns = [
    ...,
    path("graphql", GraphQLView.as_view(schema=schema)),
]
```

## WebSockets

To support graphql Subscriptions over WebSockets you need to provide a WebSocket
enabled server. The debug server can be made to support WebSockets with these
commands:

```shell
pip install 'strawberry-graphql[debug-server]'
pip install 'uvicorn[standard]'
```

## Contributing

We use [poetry](https://github.com/sdispater/poetry) to manage dependencies, to
get started follow these steps:

```shell
git clone https://github.com/strawberry-graphql/strawberry
cd strawberry
poetry install
poetry run pytest
```

This will install all the dependencies (including dev ones) and run the tests.

### Pre commit

We have a configuration for
[pre-commit](https://github.com/pre-commit/pre-commit), to add the hook run the
following command:

```shell
pre-commit install
```
