Getting started

What is GraphQL?

For an introduction to GraphQL and an overview of its concepts, please refer to the official introduction <>.

Let’s build a basic GraphQL schema from scratch.


  • Python (2.7, 3.2, 3.3, 3.4, 3.5, pypy)
  • Graphene (1.0)

Project setup

pip install "graphene>=1.0"

Creating a basic Schema

A GraphQL schema describes your data model, and provides a GraphQL server with an associated set of resolve methods that know how to fetch data.

We are going to create a very simple schema, with a Query with only one field: hello. And when we query it, it should return "World".

import graphene

class Query(graphene.ObjectType):
    hello = graphene.String()

    def resolve_hello(self, args, context, info):
        return 'World'

schema = graphene.Schema(query=Query)


Then we can start querying our schema:

result = schema.execute('{ hello }')
print['hello'] # "World"

Congrats! You got your first graphene schema working!
