gpodder-fastapi-router

A pip-installable FastAPI router that implements the gpodder.net (mygpo) HTTP API, ready to drop into any FastAPI application. Bring your own database (SQLite or PostgreSQL via async SQLAlchemy 2).

Includes:

• All mygpo 2.11 endpoints (auth, directory, devices, sync, subscriptions, episode actions, settings, lists, favorites, suggestions, clientconfig)
• HTTP Basic and session-cookie auth (works with AntennaPod, gPodder, Podverse, …)
• Admin dashboard at /dashboard — users, devices, subscriptions, stats
• CLI for offline user management (gpodder-router create-user …)
• Auto-generated OpenAPI docs at /docs and /redoc
• See docs/ for the full handbook.

Install

uv add gpodder-fastapi-router            # core
uv add "gpodder-fastapi-router[sqlite]"  # + aiosqlite driver
uv add "gpodder-fastapi-router[postgresql]"  # + asyncpg driver

Requires Python >= 3.12.

Quick start

from fastapi import FastAPI
from gpodder_router import GPodderConfig, attach

app = FastAPI()
attach(
    app,
    config=GPodderConfig(
        database_url="sqlite+aiosqlite:///./gpodder.db",
        base_url="http://localhost:8000",
    ),
)

Run:

uv run uvicorn examples.simple_app:app --reload

Register a user, then point any gpodder-compatible client at the server:

curl -X POST http://localhost:8000/api/2/auth/alice/register.json \
     -H 'Content-Type: application/json' \
     -d '{"password": "secret"}'

Mounting under a prefix

attach(app, prefix="/gpodder")
# /gpodder/api/2/auth/{username}/login.json ...

Manual integration (no auto startup hooks)

from gpodder_router import Database, GPodderConfig, build_router

cfg = GPodderConfig()
db = Database(cfg.database_url)

app = FastAPI()
app.state.gpodder_config = cfg
app.state.gpodder_db = db
app.include_router(build_router())

@app.on_event("startup")
async def _init() -> None:
    await db.create_all()

Or use the bundled lifespan:

from gpodder_router import GPodderConfig, build_router, lifespan

cfg = GPodderConfig()
app = FastAPI(lifespan=lambda a: lifespan(a, config=cfg))
app.include_router(build_router())

Configuration

GPodderConfig is a pydantic-settings model. Values can be supplied inline or via GPODDER_* environment variables.

PostgreSQL example:

GPodderConfig(
    database_url="postgresql+asyncpg://gpodder:pw@localhost:5432/gpodder",
)

Implemented endpoints

All endpoints from mygpo OpenAPI 2.11:

* register.json is an extension on top of mygpo. Disable via GPodderConfig(allow_registration=False) to require server-side provisioning.

Supported response formats: json, xml, opml, txt, jsonp.

Directory / suggestions / favorites are stub-implemented (returning empty result sets) since a self-hosted server has no global directory. The schema is in place; populate the gpodder_favorites table or override the routers to plug in your own data sources.

Programmatic user management

from gpodder_router import Database, GPodderConfig
from gpodder_router.services import users as users_svc

cfg = GPodderConfig()
db = Database(cfg.database_url)
await db.create_all()
async with db.session() as s:
    await users_svc.create_user(s, username="alice", password="secret")

Authentication

HTTP Basic, exactly as mygpo. Passwords are stored as bcrypt hashes. Path-{username} is verified against the authenticated user; a mismatch returns 400, matching the upstream contract.

Dashboard

Mounted at /dashboard (toggle with enable_dashboard, change with dashboard_prefix). The first registered user is the bootstrap admin; in production set admin_usernames=["alice", ...]. See docs/dashboard.md.

CLI

gpodder-router create-user alice           # prompts for password
gpodder-router list-users
gpodder-router set-password alice
gpodder-router delete-user bob
gpodder-router init-db

Same operations also available as python -m gpodder_router …. See docs/cli.md.

Configuration files

Three ways to configure (priority highest → lowest):

1. kwargs — GPodderConfig(database_url=..., base_url=...)
2. env — GPODDER_* variables, optionally loaded from a .env file
3. TOML — GPodderConfig.from_toml("config.toml") — see examples/config.toml

cp .env.example .env   # then edit

Docker

docker compose up -d                                 # SQLite
docker compose -f docker-compose.postgres.yml up -d  # PostgreSQL
