Busride

Many services exist which have release dates (IMDB, Goodreads, Amazon, Metacritic, etc). However, it is a pain to constantly have to monitor these sites.

Busride will allow a user to submit their api keys for these services, query a user's watchlist, and notify when relevant releases occur.

This is a non-profit personal project.

Boilerplate - fastapi-gino-arq-uvicorn

High-performance Async REST API, in Python. FastAPI + GINO + Arq + Uvicorn (powered by Redis & PostgreSQL).

Get Started

Setup

1. Clone this Repository. git clone https://github.com/leosussan/fastapi-gino-arq-uvicorn.git
2. Install Python 3.8 and poetry.
   • Recommended Method: asdf - a universal version manager (think nvm or pyenv)
     • Follow these instructions to install asdf.
     • Run the following commands from the project root:
       • asdf plugin add python
       • asdf plugin add poetry
       • asdf install -- will download & configure this project's Python + poetry setup
     • ~NOTE: your machine must have a system version of Python installed. If you don't, run the following: asdf install python 3.8.2 && asdf global python 3.8.2
   • If you have Python 3.8 and poetry installed already, please feel free to skip.
3. Install dependencies (poetry install).
4. Activate pre-commit hooks (in poetry shell, run pre-commit install).
5. Make a copy of .dist.env, rename to .env. Fill in PostgreSQL, Redis, Sentry (optional) variables.
6. Generate DB Migrations: in poetry shell, run alembic revision --autogenerate.
   • Apply migrations manually with alembic upgrade head.
   • If using the Dockerfile, migrations are applied at startup.

Run

Run Locally

NOTE: You must have PostgreSQL & Redis running locally.

1. Make sure PostgreSQL & Redis are running locally.
2. Run:
   • FastAPI Application:
     • For Active Development (w/ auto-reload): Run locally with poetry run task app
     • For Debugging (compatible w/ debuggers, no auto-reload): Configure debugger to run python app/main.py.
   • Background Task Worker:
     • For Active Development: Run poetry run task worker

Run Locally with Docker-Compose.

1. Make sure Docker is running locally.
2. Run poetry run task compose-up*.
   • Run poetry run task compose-down to spin down, clean up.

*app/settings/prestart.sh will run migrations for you before the app starts.

Build Your Application

• Create routes in /app/routes, import & add them to the ROUTERS constant in /app/main.py
• Create database models to /app/models/orm, add them to /app/models/orm/migrations/env.py for migrations
• Create pydantic models in /app/models/pydantic
• Store complex db queries in /app/models/orm/queries
• Store complex tasks in app/tasks.
• Add / edit globals to /.env, expose & import them from /app/settings/globals.py
  • Use any coroutine as a background function: store a reference in the ARQ_BACKGROUND_FUNCTIONS env.
  • Set SENTRY_DSN in your environment to enable Sentry.
• Define code to run before launch (migrations, setup, etc) in /app/settings/prestart.sh

Features

Core Dependencies

• FastAPI: touts performance on-par with NodeJS & Go + automatic Swagger + ReDoc generation.
• GINO: built on SQLAlchemy core. Lightweight, simple, asynchronous ORM for PostgreSQL.
• Arq: Asyncio + Redis = fast, resource-light job queuing & RPC.
• Uvicorn: Lightning-fast, asynchronous ASGI server.
• Optimized Dockerfile: Optimized Dockerfile for ASGI applications, from https://github.com/tiangolo/uvicorn-gunicorn-docker.

Additional Dependencies

• PostgreSQL: Robust, fully-featured, scalable, open-source.
• Redis: Fast, simple, broker for the Arq task queue.
• Pydantic: Core to FastAPI. Define how data should be in pure, canonical python; validate it with pydantic.
• Alembic: Handles database migrations. Compatible with GINO.
• SQLAlchemy_Utils: Provides essential handles & datatypes. Compatible with GINO.
• Sentry: Open-source, cloud-hosted error + event monitoring.
• Pre-Commit: automatic formatting (black + isort) and linting (flake8).
• Taskipy: Small, flexible task runner for Poetry.
