Using Celery with Flask-SocketIO

This repository contains example code based off of Miguel Grinberg's excellent blog article Using Celery with Flask and his example code.

The difference is that this code uses Flask-SocketIO (another excellent package by Miguel) to communicate status to the client without the client having to poll the server for status.

Quick Setup

1. Clone this repository.
2. Create a virtualenv and install the requirements.
3. Open a second terminal window and start a local Redis server (if you are on Linux or Mac, execute run-redis.sh to install and launch a private copy).
4. Open a third terminal window. Start a Celery worker: venv/bin/celery worker -A app.celery --loglevel=info.
5. Start the Flask application on your original terminal window: venv/bin/python app.py.
6. Go to http://localhost:5000/ and enjoy this application!
