In this tutorial screencast we'll look at creating realtime web applications. Creating realtime web applications has been possible for a while now, however up until recently it's been kind of a pain and required a big engineering effort. I think this is largely because the tools haven’t provided exactly what we needed to do realtime in a simple and painless way. Luckily this has all changed, now it's pretty easy to build realtime applications and it's my goal to prove that to you in this episode. The best way to prove this is by showing you, so we'll build a simple single page application the uses realtime features from top to bottom. The app we'll build is a realtime question & feedback application that could be used at a meetup. For example when people at the meetup have a question, they could post their question and it would be immediately streamed to everyone using the app. At it’s core it’s just a simple crud application, except all interactions happen in realtime. Here is the technology stack we'll use:. * RethinkDB (.
