Intro

GQLA is published under MIT license and doesn't provide any warranty. It is single person developed package.

No roadmap No warranty No consistency No active and fast responces to dev

Usage

Example of basic usage bellow:

# Create a GQLA class instance with name 'graphql-service'
helper = GQLA('graphql-service')  
# Define url of service as localhost
helper.url = 'localhost'  
# Define port of service 
helper.port = '8086'  
# Create a list of ignored fields (recommended values)
ignore = ['pageInfo', 'deprecationReason', 'isDeprecated', 'cursor']  
# Set list to class
helper.set_ignore(ignore)
# Request introspection
await helper.introspection()
# Request query with argument useSomeArgs='false' and specify that we don't use folder to save result
result = await helper.query_one('cerviceTestData', to_file=False, useSomeArgs='false')
# Print result
print(result)

Notice that you can use folders to save infrastructure and results:

# Create a list of ignored fields (recommended values)
ignore = ['pageInfo', 'deprecationReason', 'isDeprecated', 'cursor']  
# Create a GQLA class instance with provided settings
helper = GQLA('graphql-service', url='localhost', port=8086, ignore=ignore, usefolder=True)  
# Request introspection (saved to "gqla/graphql-service" folder)
await helper.introspection()
# Request query with argument useSomeArgs='false' and specify that we use folder to save result
result = await helper.query_one('cerviceTestData', to_file=True, useSomeArgs='false')
# Print result (can still gather result as json named _cerviceTestData from "gqla/graphql-service" folder)
print(result)

Installation

Requirements:

• aiohttp
• r/w access if using folder to save infrastucture
• python >= 3.5

Structure

Classes

• GQBase - base class of GraphQL data
• GQEnum - ENUM type of GraphQL data
• GQScalar - Scalar type of GraphQL data
• GQObject - Object type of GraphQL data
• GQModel - model of GraphQL service
• GQLA - main class

Parameters:

• _subpid - number of subtask running; No actual usage besides logging
• _model - model of GraphQL service; Conains full accessible service structure; DO NOT TOUCH
• _queries - full querries in dict format
• _ignore - list of statements to ignore during querries generation
• name - name used to define service; required to create folders if usefolder is set
• url - url of GraphQL service
• port - port of GraphQL service
• usefolder - directive to use folder to store data such as service model, querries and returned data

Methods

Notice that async meant to execute in execution loop;

• set_ignore - set _ignore field of main class;
• _can_query - service method to define ability to query;DO NOT TOUCH
• fetch_async - method to fetch querry;async
• query_one - method to generate and execute querries;async
• introspection - method to gather information about service;async
• create data - method to create model from gathered information;
• generate_querries - method to generate querries from model;
• subquery - recursive method to unwrap Objects into querries;
