Twitter Live Feed

This is a simple example of how we can use websockets to show real time twitter feed on a webpage. This repo also serves as an example for using Tornado with Django.

The frontend is written in Angular but the backend can work with any frontend framework.

Dependencies

• Python 3
• RabbitMQ
• Node.js
• Modern browser which supports WebSockets

How to run services

Before running the servies create a link from /opt/twitter-livefeed to the repository folder, this way the following commands can be run as it is.

Collector service

1. cd /opt/twitter-livefeed/collector
2. DJANGO_SETTINGS_MODULE=livefeed.settings PYTHONPATH=/opt/twitter-livefeed python collect.py

Tornado service

1. cd /opt/twitter-livefeed/tornado_app
2. DJANGO_SETTINGS_MODULE=livefeed.settings PYTHONPATH=/opt/twitter-livefeed python app.py

Websever

1. cd /opt/twitter-livefeed/frontend
2. npm install (should be done only the first time)
3. npm start

Gotchas

• If you are not getting the real time updates then before trying anything else try refreshing the web page, it's possible that the socket connection to server is not open, refreshing the page will reconnect the socket.
• If you get InsecurePlatformWarning due to SSL when you run collector service try pip install --upgrade ndg-httpsclient.
