GraphQL client for Python
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
.
The complete documentation for GQL can be found at gql.readthedocs.io.
You can install GQL with all the optional dependencies using pip:
pip install gql[all]
NOTE: See also the documentation to install GQL with less extra dependencies depending on the transports you would like to use or for alternative installation methods.
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)
Executing the above code should output the following result:
$ python basic_example.py
{'continents': [{'code': 'AF', 'name': 'Africa'}, {'code': 'AN', 'name': 'Antarctica'}, {'code': 'AS', 'name': 'Asia'}, {'code': 'EU', 'name': 'Europe'}, {'code': 'NA', 'name': 'North America'}, {'code': 'OC', 'name': 'Oceania'}, {'code': 'SA', 'name': 'South America'}]}
WARNING: Please note that this basic example won't work if you have an asyncio event loop running. In some python environments (as with Jupyter which uses IPython) an asyncio event loop is created for you. In that case you should use instead the async usage example.
