## Overview:

A RESTful Flask framework with MongoDB, Redis and Celery integrations:

Backend:

- Flask [Framework]
- MongoDB [Database]
- Redis [Cache]
- Celery + RabbitMQ [Async Tasks]

## Installing:

```sh
$ pip install dead-simple-framework
```


## Configuration:

TODO - DOCS

## Example Application (`demo.py`):

\* Celery must be running *
```sh
$ celery -A demo worker -l info
```

```python

```

- Starts a local server at http://0.0.0.0:5000/

- Serves CRUD operations for MongoDB collection `demo` at endpoint `/demo`

- Runs an asynchronous chained value calculation and insert into the `insert` collection (viewable at `/insert`)

- Runs asynchronous parallel API calls and displays the latest result at endpoint `/` (can be manually run at `/api/refresh`)
