Build a scalable Twitter clone with Django and GetStream.io

In this tutorial we are going to build a Twitter clone using Django and GetStream.io, a hosted API for newsfeed development.

We will show you how easy is to power your newsfeeds with GetStream.io. For brevity we leave out some basic Django-specific code and recommend you refer you to the Github project for the complete runnable source code. At the end of this tutorial we will have a Django app with a profile feed, a timeline feed, support for following users, hashtags and mentions.

I assume that you are familiar with Django. If you're new to Django the [official tutorial] (https://docs.djangoproject.com/en/2.0/intro/) explains it very well.

How to build a notification feed using Stream

Introduction

In this tutorial we are going to show how easy it is to build a notification feed using GetStream.io. First of all, let's quickly introduce you to our fictional example app. It's called bug-your-friends.com and allows you interact with your friends, ping them, follow them or poke them. Here's a quick list of example interactions:

• poke another user (eg. Thierry pokes Alessandra)
• follow a user (eg. Tommaso follows Iris)
• ping a user (eg. Josie pings Carolina)

Whenever a user is part of one of these interactions, we want to update his notification feed, update the number of unseen and unread
