bella-baxter-fastapi 0.1.1rc28

FastAPI integration for the Bella Baxter secret management SDK

bella-baxter-fastapi

FastAPI integration for the Bella Baxter secrets management platform. Provides a BellaDepends dependency annotation for injecting a BaxterClient into route handlers.

Installation

pip install bella-baxter-fastapi

Quickstart

from contextlib import asynccontextmanager
from fastapi import FastAPI
from bella_baxter_fastapi import init_bella, BellaDepends

@asynccontextmanager
async def lifespan(app: FastAPI):
    init_bella(api_key="bax-...")
    yield

app = FastAPI(lifespan=lifespan)

@app.get("/health")
async def health(bella: BellaDepends):
    secrets = await bella.get_all_secrets_async()
    return {"database": secrets.secrets.get("DATABASE_URL")}

init_bella()

Call once at startup (inside a lifespan handler or module level) to initialise the shared client:

from bella_baxter_fastapi import init_bella

init_bella(
    api_key="bax-...",
    baxter_url="https://api.bella-baxter.io",  # optional
)

BellaDepends

A typed Annotated dependency that injects the shared BaxterClient:

from bella_baxter_fastapi import BellaDepends

@app.get("/secrets")
async def get_secrets(bella: BellaDepends):
    resp = await bella.get_all_secrets_async()
    return resp.secrets

Configuration via environment variables

import os
from bella_baxter_fastapi import init_bella

init_bella(
    api_key=os.environ["BELLA_BAXTER_API_KEY"],
    baxter_url=os.environ.get("BELLA_BAXTER_URL", "https://api.bella-baxter.io"),
)

Authentication

Generate an API key via the CLI or the Bella WebApp:

bella api-keys create --env production --name "FastAPI Production"

Using secrets at startup (before first request)

@asynccontextmanager
async def lifespan(app: FastAPI):
    init_bella(api_key=os.environ["BELLA_BAXTER_API_KEY"])

    # Pre-fetch secrets to warm the cache
    from bella_baxter_fastapi import _get_bella_client
    client = _get_bella_client()
    secrets = await client.get_all_secrets_async()
    app.state.db_url = secrets.secrets["DATABASE_URL"]
    yield
