# Strawberry GraphQL > Python GraphQL library based on dataclasses [](https://discord.gg/ZkRTEJQ) [](https://pypi.org/project/strawberry-graphql/) ## Installation ( Quick Start ) The quick start method provides a server and CLI to get going quickly. Install with: ```shell pip install "strawberry-graphql[cli]" ``` ## 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 serve the schema using the dev server run the following command: ```shell strawberry dev app ``` Open the dev 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)), ] ``` ## Examples * [Various examples on how to use Strawberry](https://github.com/strawberry-graphql/examples) * [Full stack example using Starlette, SQLAlchemy, Typescript codegen and Next.js](https://github.com/jokull/python-ts-graphql-demo) * [Quart + Strawberry tutorial](https://github.com/rockyburt/Ketchup) ## Contributing We use [uv](https://docs.astral.sh/uv) to manage dependencies, to get started follow these steps: ```shell git clone https://github.com/strawberry-graphql/strawberry cd strawberry uv sync uv run pytest ``` For all further detail, check out the [Contributing Page](CONTRIBUTING.md) ### 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 ``` ## Links - Project homepage: https://strawberry.rocks - Repository: https://github.com/strawberry-graphql/strawberry - Issue tracker: https://github.com/strawberry-graphql/strawberry/issues - In case of sensitive bugs like security vulnerabilities, please contact patrick.arminio@gmail.com directly instead of using the issue tracker.
