Python DB-API and SQLAlchemy interface for GraphQL APIs.
Project description
graphql-db-api

A Python DB API 2.0 for GraphQL APIs
This module allows you to query GraphQL APIs using SQL.
SQLAlchemy support
This module provides a SQLAlchemy dialect.
from sqlalchemy.engine import create_engine
engine = create_engine('graphql://host:port/path?is_https=0')
Example Usage
Querying Connections
from sqlalchemy import create_engine
from sqlalchemy import text
# We use GraphQL SWAPI (The Star Wars API) c/o Netlify:
engine = create_engine('graphql://swapi-graphql.netlify.app/.netlify/functions/index')
with engine.connect() as connection:
# Demonstration of requesting nested resource of homeworld
# and then selecting fields from it
for row in connection.execute(text("select name, homeworld__name from 'allPeople?include=homeworld'")):
print(row)
Querying Lists
from sqlalchemy import create_engine
from sqlalchemy import text
engine = create_engine('graphql://pet-library.moonhighway.com/')
with engine.connect() as connection:
for row in connection.execute(text("select id, name from 'allPets?is_connection=0'")):
print(row)
Superset support
In order to use with Superset, install this package and then use the graphql
protocol in the SQLAlchemy URI like: graphql://swapi-graphql.netlify.app/.netlify/functions/index
. We install a db_engine_spec
so Superset should recognize the driver.
Roadmap
- Non-Connections top level
- Path traversal (basic)
- Path traversal (basic + nested)
- Path traversal (list / connection)
- Bearer Tokens in
Authorization
Header - Advanced Auth (e.g. with token refresh)
- Passing Headers (e.g. Auth in other locations)
- Filtering
- Sorting
- Relay Pagination
