Project description

Documentation Status

A forked and updated project of gqlclient for making requests to a GraphQL server using standard library or pydantic dataclasses to spare you from string manipulation.

Features

  • Use standard library dataclasses to specify graphql parameters and responses
  • Use pydantic dataclasses to specify graphql parameters and responses that have type validation
  • Create and execute GraphQL Queries based upon typed models
  • Create and execute GraphQL Mutations based upon typed models
  • Async support

Installation

pip install py_gql_test_client

with asyncio support

pip install py_gql_test_client[async]

Examples

Query

from pydantic.dataclasses import dataclass

from py_gql_test_client import GraphQLClient

@dataclass
class Parameters:
    attr_one: str
    attr_two: int

@dataclass
class Response:
    attr_three: int
    attr_four: str

client = GraphQLClient(gql_uri="http://localhost:5000/graphql")
parameters = Parameters(attr_one="foo", attr_two=3)
query = client.get_query(query_base="baseType", query_response_cls=Response, query_parameters=parameters)
print(query)
#{'query': '{baseType(attr_one: "foo", attr_two: 3){attr_three, attr_four} }'}
response = client.execute_gql_query(query_base="baseType", query_response_cls=Response, query_parameters=parameters)
print(response)
#{"baseType"{"attr_three":5, "attr_four":"bar"}}

Mutation

from pydantic.dataclasses import dataclass

from py_gql_test_client import GraphQLClient


@dataclass
class Parameters:
    attr_one: str
    attr_two: int


@dataclass
class Response:
    attr_three: int
    attr_four: str

client = GraphQLClient(gql_uri="http://localhost:5000/graphql")
parameters = Parameters(attr_one="foo", attr_two=3)
query = client.get_mutation(mutation_base="baseMutation", mutation_response_cls=Response, mutation_parameters=parameters)
print(query)
#{'query': 'mutation baseType {baseType(attr_one: "foo", attr_two: 3){ok, attr_three, attr_four} }', 'operationName': 'baseType'}

response = client.execute_gql_mutation(mutation_base="baseMutation", mutation_response_cls=Response, mutation_parameters=parameters)
print(response)
#{"baseMutation": {"ok": true, "Response": {"attr_three":5, "attr_four":"bar"} }}

Encoders

from dataclasses import dataclass

from py_gql_test_client import GraphQLClient
from py_gql_test_client import GraphQLClient, dataclass_encoder

# set the default encoder to dataclass_encoder
client = GraphQLClient(gql_uri="http://127.0.0.1:30003/graphql", default_response_encoder=dataclass_encoder)

@dataclass
class QueryResponse:
    workflowId: int
    workflowName: str
    workflowDescription: str

response = client.execute_gql_query("workflows", QueryResponse)
print(response)
# Response type is a list of dataclasses
# [QueryResponse(workflowId=1, workflowName='gql3_full - workflow_name', workflowDescription='gql3_full - workflow_description'), QueryResponse(workflowId=2, workflowName='VBI base calibration', workflowDescription='The base set of calibration tasks for VBI.'), QueryResponse(workflowId=3, workflowName='VISP base calibration', workflowDescription='The base set of calibration tasks for VISP.'), QueryResponse(workflowId=4, workflowName='VTF base calibration', workflowDescription='The base set of calibration tasks for VTF.'), QueryResponse(workflowId=5, workflowName='DLNIRSP base calibration', workflowDescription='The base set of calibration tasks for DLNIRSP.'), QueryResponse(workflowId=6, workflowName='CRYONIRSP base calibration', workflowDescription='The base set of calibration tasks for CRYONIRSP.')]

from py_gql_test_client import json_encoder
# for this call override the default encoder to the json encoder
response = client.execute_gql_query("workflows",QueryResponse, response_encoder=json_encoder)
print(response)
# Response is a json formatted string
# '{"workflows": [{"workflowId": 1, "workflowName": "gql3_full - workflow_name", "workflowDescription": "gql3_full - workflow_description"}, {"workflowId": 2, "workflowName": "VBI base calibration", "workflowDescription": "The base set of calibration tasks for VBI."}, {"workflowId": 3, "workflowName": "VISP base calibration", "workflowDescription": "The base set of calibration tasks for VISP."}, {"workflowId": 4, "workflowName": "VTF base calibration", "workflowDescription": "The base set of calibration tasks for VTF."}, {"workflowId": 5, "workflowName": "DLNIRSP base calibration", "workflowDescription": "The base set of calibration tasks for DLNIRSP."}, {"workflowId": 6, "workflowName": "CRYONIRSP base calibration", "workflowDescription": "The base set of calibration tasks for CRYONIRSP."}]}'
