tartiflette-asgi (previously tartiflette-starlette) is a wrapper that provides ASGI support for the Tartiflette Python GraphQL engine.

It is ideal for serving a GraphQL API over HTTP, or adding a GraphQL API endpoint to an existing ASGI application.

Full documentation is available at: https://tartiflette.github.io/tartiflette-asgi

Requirements

tartiflette-asgi is compatible with:

• Python 3.6, 3.7 or 3.8.
• Tartiflette 1.x.

Quickstart

First, install Tartiflette's external dependencies, as explained in the Tartiflette tutorial.

Then, you can install Tartiflette and tartiflette-asgi using pip:

pip install tartiflette "tartiflette-asgi==0.*"

You'll also need an ASGI web server. We'll use Uvicorn here:

pip install uvicorn

Create an application that exposes a TartifletteApp instance:

from tartiflette import Resolver
from tartiflette_asgi import TartifletteApp

@Resolver("Query.hello")
async def hello(parent, args, context, info):
    name = args["name"]
    return f"Hello, {name}!"

sdl = "type Query { hello(name: String): String }"
app = TartifletteApp(sdl=sdl, path="/graphql")

Save this file as graphql.py, then start the server:

uvicorn graphql:app

Make an HTTP request containing a GraphQL query:

curl http://localhost:8000/graphql -d '{ hello(name: "Chuck") }' -H "Content-Type: application/graphql"

You should get the following JSON response:

{"data": {"hello": "Hello, Chuck!"}}

0.5.2 - 2019-10-09

Added

• Add support for Python 3.8. (Pull #55)

Fixed

• Type annotations are now correctly detected by mypy. (Pull #66)
• Fix a bug that prevented the GraphiQL web interface from making queries when the application was mounted on a parent ASGI app. (Pull #51)

0.5.1 - 2019-07-16

Fixed

• Fixed a bug that prevented accessing the GraphiQL interface when subscriptions were not enabled.

0.5.0 - 2019-07-12

Added

• Support for Tartiflette 0.12.x.

Changed

• Due to the new engine cooking API in Tartiflette 0.12, TartifletteApp now includes a startup event handler responsible for building the GraphQL engine. If submounting, it must be registered on the parent ASGI app. Helpers in the mount module take care of this for you.

Removed
