## Health v2 (maintenance only)
Score: 32/100 (v2, computed 2026-09-02T17:46:02.011165+00:00)
- activity 0, release rhythm 35, longevity 100
- inputs: {"age_days": 4265, "days_push": 1338, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
Example code accompanying Miguel Grinberg's blog article 'Using Celery with Flask', demonstrating how to run background tasks with Celery in a Flask application. It includes two demos: sending emails asynchronously and launching asynchronous jobs with progress updates in the web page.

## Use cases
- learn how to integrate Celery with Flask
- run background tasks in a Flask app
- send emails asynchronously from a web application
- show progress updates for long-running jobs in the browser
- set up a Celery worker with Redis as broker
- example of scalable task queue architecture in Python

## When to choose
- you are learning Celery and Flask integration from a well-known tutorial
- you need a minimal working reference for background tasks in Flask
- you want to see email sending and progress-tracking task patterns

## When to avoid
- you need a production-ready task queue solution rather than example code
- you use a framework other than Flask
- you expect active development, new features, or support

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: workflow-automation, web-framework, message-queue, email
- domain: web-development, backend, developer-tools, tutorials
- platform: python, cross-platform
- tags: celery, flask, background-tasks, task-queue, redis, example-code, tutorial
