The most up-to-date book to learn Ember Octane

Trusted by: Toptal Firebase AirPair Nathan Barry
Rock&Roll with Ember.js Octane

Build ambitious apps with confidence

Ember.js is a kick-ass framework for building web applications. It's the only tool you need (on the client-side) to craft your idea into a working wonder. However, its strong opinions and heavy reliance on “convention over configuration” can give developers who are new to the framework a hard time figuring out how Ember wants them to do things.

This book helps to overcome that initial frustration, and help you grok Ember a lot faster, by pinpointing the core concepts and explaining them in detail. Once you understand them you are on your way to taming and mastering Ember.js. So don't fear the learning curve.

This book -- like Ember itself -- is for teams and individuals who want the productivity boost that comes from shared community solutions. Instead of reinventing the wheel, use Ember. Instead of scouring the web for advice on how to use Ember, read this book.

The book guides you through the steps of building a real application so that you can see how the concepts are applied in practice. You'll learn about the building blocks of Ember one by one, in a way that crushes the steep learning curve. Knowledge is dripped in slowly, chapter by chapter, to prevent you from drowning in a sea of novel information. By improving an existing and working application, you will learn more quickly and new knowledge will sink in deeper.

This book is a fabulous, approachable, foray into Emberjs that makes the learning curve much less scary. I just wish it had been available sooner for students in my previous classes.

Few programming books have left me with the comprehensive "big picture" understanding that this one did. It completely made me fall in love with #EmberJS, and introduced me to an incredible community of developers and friends.

Once upon a time...

It all started in September 2013. Having just returned from the first European Ember.js conference, my enthusiasm went through the roof. I wanted to spread the word, for people to realize how beautiful Ember is, for them to know that Ember.js is not that hard to learn. It's just a matter of having the core concepts internalized.

So without proper equipment (and after a few episodes, with a ~$80 mic) I started producing screencasts, a series in which a simple application is developed step-by-step. I sent the first few to my subscribers and kept producing them. And people seemed to have liked them.

Once the screencast series was finished, I switched to blog posts and lengthier articles, and in 2014 I committed to posting something of value each week. Then, after a long labor of (mostly) love, I published the 1st edition of the book in Feburary 2015, that used the then stable Ember version, 1.10.

I was not done, though. As Ember made progress in a neck breaking pace, I kept the book up-to-date with the actual stable version of the framework, and adding material that covered the new features.

Version 2 of the book, that is running on Ember 2, was published about 6 months later and I've been updating the book for every minor version ever since.

Buy once, get all minor updates for free

The first edition of this book followed Ember's journey to its 2.0 release. As Ember gracefully shedded old syntaxes, the book's content was updated not to use those syntaxes, either. When a new feature appeared, I added a section about it, trying to find a practical example for it in the application.

Since Ember follows a 6-week release cycle, that meant frequent book updates in the past, free for all of my customers. I'll follow the same policy on the road to the next Ember milestone and keep the content fresh. It might happen –as it did– that I skip a version, mostly if no new features were introduced in Ember and no deprecations were made.

I have to say Balint has done an outstanding job with his ebook. The product and his most excellent support and follow-through (including regular updates to the content) have all felt seamless and caring from the customer’s end. A class act all around.

Most of the time guides make you code perfectly from the beginning, without explaining why and how you should get these results.

On the other hand, R&R is written with the typical programmer mindset, and not a teacher one, that’s top-tier pedagogy 🎉

For a week now, Rock and Roll with Ember.JS has been my cuddle buddy. Every day I find a cozy spot, pour tea, and dive deep into Ember. Reading isn’t my preferred learning style; however, this book has an amazing hands-on section! It allows you to try your hand at each concept instead of just reading about it. I’m almost done with the lessons and I am happy to say I’ve learned a ton!

It's great that there's an up-to-date resource on Ember, apart from the official docs. For me, the documentation works best as a reference when you already know what you're doing. For learning I prefer a dedicated resource - a book or a video course, which incrementally guides you towards proficiency.

About me

Hello there, I'm Balint Erdi.

I have a long history of building web applications and have mostly been a back-end guy.

On a grey, chilly February day in 2013 that I’ll never forget (maybe it was January?) I got acquainted with Ember.js. Ember.js made that day bright and the ones that came after that. After learning the ropes I shifted gears and have been proselytizing for Ember since that summer.

I gave workshops at EmberConf and Eurucamp, and presented at EmberConf, EmberFest, AgentConf and Arrrrcamp. I started an Ember.js mailing list, made an introductory screencast series and have been sending Ember content to my dear subscribers on a weekly basis. I have also written guest articles for Safari Books Online, AirPair, Firebase and Toptal.

I guess you could say I’m pretty passionate about Ember.

Oh, and I love rock & roll, obviously.

You want code with that?

This gives you access to the source code repository of the app we build in the book. The end of each chapter is assigned the aptly named tag, so you can quicky jump to a chapter, check out the code or even tweak it to your liking (and to improve your learning).

Source code access

One chapter, one commit

I thoroughly enjoyed the read and coding along with you as you introduced, built upon and refactored the code. It follows the way most people write their code, myself included, and I appreciated that thoughtful approach to your material. … I"ll conclude by saying this: your book immediately gave me the confidence to go full bore into our MVP using Ember, and for that I am truly grateful.

Hmm, I’m not sure...

  • Does the book really speak Octane?

    It absolutely does! Glimmer components, tracked properties, ES6 classes – all the great stuff that makes Octane an amazing developer experience.

  • Is this book for me?

    The book starts from the very basics (installing ember-cli, writing your first template, etc.) so if you completely get Ember, this book is probably not for you. If you are just starting out (or about to) or want to understand fundamental concepts in Ember, the book is definitely for you.

  • Do you offer discounts to students?

    Yes! Please write me an email and tell me about your school. I'll then send you a discount code for the book.

  • Everything is changing so fast; won't the content be outdated by next week?

    As Ember.js moves towards the next major version (edition), I will keep updating the content of the book so that it stays void of deprecation warnings and does not promote practices that are no longer considered idiomatic. In practical terms, this means I'll release a book update after each new stable Ember release, once about every six weeks.

  • I heard Ember is so hard. Will this book help me understand it?

    I think there are a handful of key concepts in Ember.js that you need to understand to master it (probably the main one among these is routing). Once you understand these, Ember is not that hard. The intention of the book is to introduce concepts by way of building an actual application, so you see them applied in practice right away. That also helps the learning process. I also encourage you to work through the book as you read it, since that makes things sink in even deeper. You have access to the code repository if you have purchased the middle- or high-tier package. If I failed to explain Ember for you, please send me your purchase receipt to within 60 days of purchase and I’ll issue a refund.

  • Updates are free until when exactly?

    Octane is the first edition of the framework. Before, it had major versions as most other libraries do, so it was easier for me to say "free updates until next major version". I expect Ember to continue with editions to mark when a set of significant features have all landed in the framework. If so, my guarantee is "free updates until next edition", otherwise I'll probably fall back to the next major version guarantee that in this case would be 5.0.

  • How can I get an invoice for my purchase (and reclaim EU VAT)?

    After the purchase Gumroad will send you an email with a receipt that has a link to their invoice generator. There, you'll be able to fill out your company details and, if you're a EU company, reclaim the EU VAT. Read more about this in this FAQ article. or watch the video I recorded about it.

  • I get a "Sorry, this item is not available in your location" error when trying to buy the book. What should I do?

    This has happened extremely rarely (one single reported incident so far) but if it does happen to you, your best bet is to use a VPN and access the book's landing page that way. There are lots of stand-alone VPN apps and browser extensions that you can use.

  • What if I don't buy code access but it later turns out I'd like it?

    No problem! Just send me your purchase receipt to, and I will upgrade you for the price difference.

  • Is the book DRM protected?

    No, it’s not. If you would like to share it with a couple of colleagues, go ahead. If you like the book, I'd appreciate if you bought licenses individually. If you're at least five people, please buy a Team License.

  • What if I don't like the book?

    I offer a 60-day moneyback guarantee. No strings attached, just send your purchase receipt (or email address) to or reply to the welcome email that you received when you purchased.

  • I still have a question, how can I reach you?

    That's totally my fault, could you send a quick message to with your question? Thank you.
