GraphQL Support for Google AppEngine [DEPRECATED - Looking for maintainers]

Graphene GAE (deprecated!)

⚠️ This repository is deprecated due to lack of maintainers. If you're interested in taking over let us know via the Graphene Slack

A Google AppEngine integration library for Graphene

• Free software: BSD license
• Documentation: https://graphene_gae.readthedocs.org.

Upgrade Notes

If you're upgrading from an older version (pre 2.0 version) please check out the Graphene Upgrade Guide.

Installation

To install Graphene-GAE on your AppEngine project, go to your project folder and runthis command in your shell:

pip install graphene-gae -t ./libs

This will install the library and its dependencies to the libs folder under your projects root - so the dependencies get uploaded withyour GAE project when you publish your app.

Make sure the libs folder is in your python path by adding the following to your `appengine_config.py`:

import sys

for path in ['libs']:
    if path not in sys.path:
        sys.path[0:0] = [path]

Examples

Here's a simple GAE model:

class Article(ndb.Model):
    headline = ndb.StringProperty()
    summary = ndb.TextProperty()
    text = ndb.TextProperty()

    author_key = ndb.KeyProperty(kind='Author')

    created_at = ndb.DateTimeProperty(auto_now_add=True)
    updated_at = ndb.DateTimeProperty(auto_now=True)

To create a GraphQL schema for it you simply have to write the following:

import graphene
from graphene_gae import NdbObjectType

class ArticleType(NdbObjectType):
    class Meta:
        model = Article

class QueryRoot(graphene.ObjectType):
    articles = graphene.List(ArticleType)

    @graphene.resolve_only_args
    def resolve_articles(self):
        return Article.query()

schema = graphene.Schema(query=QueryRoot)

Then you can simply query the schema:

query = '''
    query GetArticles {
      articles {
        headline,
        summary,
        created_at
      }
    }
'''
result = schema.execute(query)
