Print edition: The book is also available in print edition on Amazon.
The second edition is out: more than 50 extra pages of content, including a brand new process for structuring your database. Read more about the changes in this article. This update contains pages of information not found anywhere else coming directly from Bubble's head engineers.
Bubble is changing the way web applications are built. Anyone can now build the next big social network, SaaS or app startup.
But its amazing flexibility comes at a cost: the freedom to build your app in any way you want also let's you set it up in ways that are not optimal for high performance and scaling. Bubble's official documentation is designed to help you set up an app quickly and easily, not to promote methods that leverage Bubble's most advanced features to speed up your pages, workflows and database.
WHAT THE BOOK TEACHES
It's easy to think of performance as one thing: how fast an app can process a request. But in truth, performance is a complex combination of software, hardware, your user's device, app design and psychology.
Every app works on two layers: one layer is hidden and one is visible: one is complex to the point where a human brain cannot even begin to process it - the other working solely and intentionally to hide that fact. Your job as a developer is to break the chain between the two layers and make complicated stuff seem easy
User-perceived performance is the only performance that matters. In the stage show that is your app, you are the magician. You get to tell the user what to do and where to direct his attention. You get to prepare the stage, the machinery, the tools and equipment and train the beautiful assistant to do exactly what you want to avoid breaking the illusion. The user doesn’t need to know what’s going on backstage.
If you do your job right, they’ll believe it’s magic. If you reveal your trick, or complain how hard it is to do, you’re not helping your audience - you’re ruining their evening.
THE BOOK DIVES DEEP INTO BOTH LAYERS
- how to set up your app to load pages, process workflows and edit database records efficiently
- how to communicate well to your users so that your app seems faster than it really is
Over 200 pages, numerous examples, scenarios, illustrations and screenshots, the book doesn't teach set general best practices: it gives you the tools to optimize your app in ways that make sense for your unique project.
