How to build a notification feed using Stream

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

/**
* Scales an image to fit within a bounds with a size governed by
* the passed size. Also keeps the aspect ratio.
*
* Switch MIN to MAX for aspect fill instead of fit.
*
* @param newSize the size of the bounds the image must fit within.
* @return a new scaled image.
