GQL

This is a GraphQL client for Python 3.6+.Plays nicely with graphene, graphql-core, graphql-js and any other GraphQL implementation compatible with the spec.

GQL architecture is inspired by React-Relay and Apollo-Client.

WARNING: Please note that the following documentation describes the current version which is currently only available as a pre-releaseThe documentation for the 2.x version compatible with python<3.6 is available in the 2.x branch

Documentation

The complete documentation for GQL can be found atgql.readthedocs.io.

Features

The main features of GQL are:

• Execute GraphQL queries using different protocols (http, websockets, ...)
• Possibility to validate the queries locally using a GraphQL schema provided locally or fetched from the backend using an instrospection query
• Supports GraphQL queries, mutations and subscriptions
• Supports sync or async usage, allowing concurrent requests
• Supports File uploads
• gql-cli script to execute GraphQL queries from the command line
• DSL module to compose GraphQL queries dynamically

Installation

WARNING: Please note that the following documentation describes the current version which is currently only available as a pre-release and needs to be installed with

$ pip install --pre gql[all]

NOTE: See also the documentation to install GQL with less extra dependencies

Usage

Basic usage

from gql import gql, Client
from gql.transport.aiohttp import AIOHTTPTransport

# Select your transport with a defined url endpoint
transport = AIOHTTPTransport(url="https://countries.trevorblades.com/")

# Create a GraphQL client using the defined transport
client = Client(transport=transport, fetch_schema_from_transport=True)

# Provide a GraphQL query
query = gql(
    """
    query getContinents {
      continents {
        code
        name
      }
    }
"""
)

# Execute the query on the transport
result = client.execute(query)
print(result)

WARNING: Please note that this basic example won't work if you have an asyncio event loop running. In somepython environments (as with Jupyter which uses IPython) an asyncio event loop is created for you. In that case youshould use instead the async usage example.
