## Overview:

A dead simple framework for web applications:

Backend:

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

## Installing:

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


## Configuration:

TODO

## Example Application (`demo.py`):
\* MongoDB must be running *
```sh
$ mongod
```


```sh
$ rabbitmq-server
$ celery -A demo worker -l info
```

```python

# Required boilerplate to run the app or the scheduler [RabbitMQ must be running]

```

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

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

- Runs and returns the result of an asynchronous Celery task at endpoint `/`

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

- Runs an asynchronous API call and displays the result at endpoint `/call`
