graphene-tornado
================

A project for running `Graphene <http://graphene-python.org/>`__ on top
of `Tornado <http://www.tornadoweb.org/>`__ in Python 2 and 3. The
codebase is a port of
`graphene-django <https://github.com/graphql-python/graphene-django>`__.

Getting started
===============

Create a Tornado application and add the GraphQL handlers:

.. code:: python

   import tornado.web
   from tornado.ioloop import IOLoop

   from graphene_tornado.schema import schema
   from graphene_tornado.tornado_graphql_handler import TornadoGraphQLHandler


   class ExampleApplication(tornado.web.Application):

       def __init__(self):
           handlers = [
               (r'/graphql', TornadoGraphQLHandler, dict(graphiql=True, schema=schema)),
               (r'/graphql/batch', TornadoGraphQLHandler, dict(graphiql=True, schema=schema, batch=True)),
               (r'/graphql/graphiql', TornadoGraphQLHandler, dict(graphiql=True, schema=schema))
           ]
           tornado.web.Application.__init__(self, handlers)

   if __name__ == '__main__':
       app = ExampleApplication()
       app.listen(5000)
       IOLoop.instance().start()

When writing your resolvers, decorate them with either Tornado’s
``@coroutine`` decorator for Python 2.7:

.. code:: python

   @gen.coroutine
   def resolve_foo(self, info):
     foo = yield db.get_foo()
     raise Return(foo)

Or use the ``async`` / ``await`` pattern in Python 3:

.. code:: python

   async def resolve_foo(self, info):
     foo = await db.get_foo()
     return foo
