Screencast for Learn Enough Action Cable to Be Dangerous

Oct 26, 2016 • posted by Michael Hartl

I’ve just released the screencast for Learn Enough Action Cable to Be Dangerous, which teaches you how to make real-time web applications using Rails and the WebSocket Protocol.

This is cutting-edge web development, the kind of thing that gives you a leg up on the competition when landing a contract or getting a job.

The Action Cable sample app is a real-time chat application, and for this kind of app the screencast format really shines. It’s hard to completely capture the dynamic nature of Action Cable in a written tutorial, but with a screencast you can really see the app come to life.

Topics include:

  • Upgrading a Rails app to Action Cable
  • Message broadcasts using WebSockets
  • Polishing the User Interface with CoffeeScript
  • Advanced enhancements like Markdown support and @-mention notifications

Anyone interested in building real-time apps will benefit from both the ebook and video versions of Learn Enough Action Cable to Be Dangerous.

There are two main ways to get it:

  1. Buy the downloadable ebooks & videos: Get EPUB/MOBI/PDF ebooks & over 2 hours of MP4 videos.
  2. Join the Learn Enough Society: Get access to a special enhanced online version (with community answers to exercises) and free streaming versions of all 2+ hours of the Action Cable screencasts.

Either way, I hope you enjoy learning enough Action Cable to be dangerous!

I’m Michael Hartl—author, educator, and entrepreneur. I’m probably best known as the creator of the Ruby on Rails Tutorial, a book and screencast series that together constitute one of the leading introductions to web development. Once called his “favorite book” by Wikipedia founder Jimmy Wales, the Ruby on Rails Tutorial currently has over 150 5-star reviews at Amazon. I’m also (in)famous for creating Tau Day and The Tau Manifesto, which have inspired an international movement dedicated to the proposition that “pi is wrong.” (For example, as a result of The Tau Manifesto, MIT releases their admissions decisions each year at “Tau Time” (6:28 p.m.), and typing tau/2 at Google yields 3.14159…) Finally, I’m a founder of Softcover, a publishing system and sales platform for technical authors, which among other things powers both The Tau Manifesto and the Ruby on Rails Tutorial.

I’m a graduate of Harvard College and have a Ph.D. in Physics from Caltech, where I studied black hole dynamics and was an award-winning instructor in theoretical and computational physics. I’m also an alumnus of Y Combinator, the entrepreneur program that has produced companies such as Dropbox and Airbnb. (Alas, my own Y Combinator startup was neither Dropbox nor Airbnb.)
