Id like to first thank my wife Amy, who gave me the encouragement and space to spend time every morning writing this book (twice).

Id also like to thank my first edition editor, Fahmida Rashid, as well as the editor of this edition, Katharine Dvorak, who helped me navigate the ever-changing JavaScript ecosystem so we could give you an updated book that actually went to print.

Id further like to thank the many people who reviewed this new edition: Luis Miguel Cabezas Granado, Fabrizio Cucci, Cameron Jacoby, Nigel Lowry, David McClain, Nick McGinness, Peter Perlepes, Sven Riedel, Tibor Simic, and Matthew White.

Finally, Id like to thank the contributors to the software youre learning about in this book. To the people who have given their free time to make Ruby, Rails, Postgres, Angular, Bootstrap, PhantomJS, Testdouble, Poltergeist, Devise, Capybara, RSpec, Database Cleaner, Yarn, and all the other open source software that are far too numerous to list here, thank you. Without your work, most developers would have a hard time doing their jobs.

Think about what part of an application youre most comfortable working with. If youre a Rails developer, theres a good chance you prefer the back end, the Ruby code that powers the business logic of your application. What if you felt equally comfortable working with the database, such as tweaking queries and using advanced features of your database system? What if you were also comfortable working with the JavaScript and CSS necessary to make dynamic, usable, attractive user interfaces?

If you had that level of comfort at every level of the application stack, you would possess great power as a developer to quickly produce high-quality software. Your ability to solve problems would not be restricted by the tools available via a single framework, nor would you be at the mercy of hard-to-find specialists to help you with what are, in reality, simple engineering tasks.

The Rails framework encourages developers not to peer too closely into the database. Rails steers you away from JavaScript frameworks in favor of its sprinkling approach, where content is all rendered server-side. This book is going to open your eyes to all the things you can accomplish with your database, and set you on a path that includes JavaScript frameworks. With Rails acting as the foundation of what you do, youll learn how to embrace all other parts of the application stack.
