# stream-data

Data Streaming application using Django Channels

It provides API endpoints for your Django application that can push data to connected clients. Data is sent using the Server-Sent Events protocol (SSE), in which data is streamed over a never-ending HTTP response.

For example, endpoint, `/events/`, that a client could connect to with a GET request:

```http

GET /events/ HTTP/1.1

Host: api.example.com

Accept: text/event-stream

```

The client would receive a streaming HTTP response with content looking like this:

```http

HTTP/1.1 200 OK

Transfer-Encoding: chunked

Connection: Transfer-Encoding

Content-Type: text/event-stream

event: message

data: {"foo": "bar"}

event: message

data: {"bar": "baz"}

...

```

## Features:

* Easy to consume from browsers or native applications.

* Highly reliable. Events can be persisted to your database, so clients can recover if they get disconnected.

* Set per-user channel permissions.

## How to Setup:

python3 is assumed to be installed, if not do the same

```

virtualenv venv

pip install -r requirements.txt

python manage.py migrate

python manage.py makemigrations

python manage.py runserver

```

for Authorization: channelmanager in stream app

for Generating data: generators.py

### for Scaling and Large UserBase:

you need to run multiple instances of your Django project for high availability, or need to push data from management commands, or need to be able to scale to a large number of connections, you can introduce a GRIP proxy layer (such as [Pushpin](https://pushpin.org) or [Fanout Cloud](https://fanout.io)) into your architecture.
