quillsql 3.0.0

Quill SDK for Python.

Quill Python SDK

Quickstart

First, install the quillsql package by running:

$ pip install quillsql

Then, add a /quill endpoint to your existing python server. For example, if you were running a FASTAPI app, you would just add the endpoint like this:

from quillsql import Quill

quill = Quill(
    private_key=os.getenv("QULL_PRIVATE_KEY"),
    database_connection_string=os.getenv("POSTGRES_READ"),
    database_type="postgresql"
)

security = HTTPBearer()

async def authenticate_jwt(token: str = Depends(security)):
    # Your JWT validation logic here
    # Return user object or raise HTTPException
    user = validate_jwt_token(token.credentials)
    return user

@app.post("/quill")
async def quill_post(data: Request, user: dict = Depends(authenticate_jwt)):
    # assuming user fetched via auth middleware has an userId
    user_id = user["user_id"]
    body = await data.json()
    metadata = body.get("metadata")

    result = await quill.query(
        tenants=[{"tenantField": "user_id", "tenantIds": [user_id]}],
        metadata=metadata
    )
    return result

Then you can run your app like normally. Pass in this route to our react library on the frontend and you all set!

Streaming

from quillsql import Quill
from fastapi.responses import StreamingResponse
import asyncio

quill = Quill(
    private_key=os.getenv("QULL_PRIVATE_KEY"),
    database_connection_string=os.getenv("POSTGRES_READ"),
    database_type="postgresql"
)

@app.post("/quill-stream")
async def quill_post(data: Request, user: dict = Depends(authenticate_jwt)):
    # assuming user fetched via auth middleware has an userId
    user_id = user["user_id"]
    body = await data.json()
    metadata = body.get("metadata")

    quill_stream = quill.stream(
        tenants=[{"tenantField": "user_id", "tenantIds": [user_id]}],
        metadata=metadata,
    )

    async def event_generator():
        # Full event types list: https://ai-sdk.dev/docs/ai-sdk-ui/stream-protocol#data-stream-protocol
        async for event in quill_stream:
            if event["type"] == "start":
                pass
            elif event["type"] == "text-delta":
                yield event['delta']
            elif event["type"] == "finish":
                return
            elif event["type"] == "error":
                yield event['errorText']
            await asyncio.sleep(0)

    return StreamingResponse(event_generator(), media_type="text/event-stream")
