GQLSpection

CLI tool and Python 2.7+ compatible library for parsing GraphQL introspection query and automatic query generation.

License Python Versions Jython Version

Main branch Dev branch Coverage

Installation

GQLSpection is available on PyPI (Python 2.7 and Python 3+ versions are supported).

Regular installation:

$ pip install gqlspection[cli]

Usage of the CLI tool

Load schema from file and print all query and mutation names in the schema:

$ gqlspection -f schema.json -l all

Send introspection query and generate queries & mutations for everything:

$ gqlspection -u https://.../graphql

Generate a single query:

$ gqlspection -u https://.../graphql -q something

Generate a number of mutations:

$ gqlspection -f schema.json -m one,two,three

Full help

$ ./gqlspection -h
Usage: gqlspection [OPTIONS]

Options:
  -f, --file TEXT      File with the GraphQL schema (introspection JSON).
  -u, --url TEXT       URL of the GraphQL endpoint with enabled introspection.

  -l, --list TEXT      Parse GraphQL schema and list queries, mutations or
                       both of them (valid values are: 'queries', 'mutations'
                       or 'all').

  -q, --query TEXT     Only print named queries (argument is a comma-separated
                       list of query names).

  -m, --mutation TEXT  Only print named mutations (argument is a comma-
                       separated list of mutation names).

  -Q, --all-queries    Only print queries (by default both queries and
                       mutations are printed).

  -M, --all-mutations  Only print mutations (by default both queries and
                       mutations are printed).

  -h, --help           Show this message and exit.

Usage of the Python library

Import the library:

>>> from gqlspection import GQLSchema

Send introspection query and print a single query:

>>> schema = GQLSchema(url='https://.../graphql')
>>> query = schema.generate_query('SOME_TYPE')
>>> print(query.str)

Parse introspection schema from a JSON file and print all mutations:

>>> from pathlib import Path
>>> import json
>>> data = json.loads(Path(FILE_NAME).read_text())
>>> schema = GQLSchema(json=data)
>>> for field in schema.mutation.fields:
>>>     print(schema.generate_mutation(field).str())
