This book will focus primarily on client-side architecture, although it will also cover server-side topics, such as basic RESTful APIs and Node. The trend is that a great deal of the application logic is getting pushed to the client. It was once the case that the server environment would handle things like templating and communication with vendor services. Now, it’s common to deal with both of those jobs inside the browser.
Code organization, modularity, and reuse
Separation of concerns on the client side (MVC, etc.)
Communicating with servers and APIs
Designing and programming RESTful APIs with Node.js
Building, testing, collaboration, deployment, and scaling
Expanding reach via internationalization
Google and Wikipedia can be handy guides to help you through, as well. Wikipedia is a fairly good reference for software design patterns.
It’s difficult to overstate the importance of unit testing. Unit tests are used throughout this book. By the time you reach the end, you should be accustomed to seeing and writing them. As you practice the concepts you read about, start by writing the tests first. You’ll get a better understanding of the problem domain, and you’ll be forced to think through the design for your solution and the interface you create for it. Designing for unit tests also forces you to keep your code decoupled. The discipline of writing testable, decoupled code will serve you well your entire career.
For a reference on unit tests and code style, see Appendix A.
