Realtime Notifications with ActionCable

In this episode we're going to be adding realtime notifications into your app using ActionCable. We've talked about notifications a few times in the past and we used AJAX polling for that. 95% of the time, polling is the solution that would be recommended for it.

But if you're looking for a good introduction into ActionCable then this is a decent one because we're only really using it for one way from the server side to the client side.

Getting started

So to get started we're starting with an app that has Bootstrap installed and then we created a Main controller with an index view which is where we will list our Notifications as for this example.

Before we generate our channels let's install a few things

This guide assumes that you recently run brew upgrade postgresql and discovered to your dismay that you accidentally bumped from one major version to another: say 9.3.x to 9.4.x. Yes, that is a major version bump in PG land.

First let's check something.

brew info postgresql

The top of what gets printed as a result is the most important:

start new with session name:

Share Counts

I have always struggled with getting all the various share buttons from Facebook, Twitter, Google Plus, Pinterest, etc to align correctly and to not look like a tacky explosion of buttons. Seeing a number of sites rolling their own share buttons with counts, for example The Next Web I decided to look into the various APIs on how to simply return the share count.

If you want to roll up all of these into a single jQuery plugin check out Sharrre

Many of these API calls and methods are undocumented, so anticipate that they will change in the future. Also, if you are planning on rolling these out across a site I would recommend creating a simple endpoint that periodically caches results from all of the APIs so that you are not overloading the services will requests.

Building a Facebook application with Rails and hosting it in Heroku

Introduction

Facebook has given a big step in simplicity with its Graph API and the creation of the Open Graph protocol, now more than ever it's easier to read and write data from and to the socalled social graph.

You could turn your webpage into a fully-featured Facebook-like page, just like if you were inside Facebook, you can give your users the ability to sign in with their Facebook credentials, customize your users' experience with parameters taken from their Facebook profiles, you could add a Like button to every object in your page as images, songs, articles, etc., tell your users which friends of theirs have liked your content, and a lot of things more, oh, I forgot to mention something, all of this with total ease. Yes, I know you could do it with Facebook Connect, but I said "with ease".
