How to Use GraphQL with Python

In this tutorial, we will try to use the GraphQL library in python, Strawberry GraphQL. Python GraphQL library based on dataclasses.

to install Strawberry GraphQL:

pip install strawberry-graphql

Example sourcecode:

import strawberry


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


@strawberry.type
class Query:
    @strawberry.field
    def user(self, info) -> User:
        return User(name="emka", age=20)


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:

strawberry server app

Open the debug server by clicking on the following link: http://0.0.0.0:8000/graphql

This will open GraphiQL where you can test the API.
