This chapter introduced the concept of single-page applications and implemented a Taskify frontend as an SPA, connecting to the Spring-based API server on the backend. We got a fair understanding of Ember.js and its tools as we built our frontend. Spring and Ember have together simplified the building of an otherwise complex rich web application of this type. The use of Ember is just an illustration of how Spring can power the backend of modern SPAs. Spring powers SPAs built on other frameworks, such as Angular, React, and Backbone, created by teams across the globe.

So far, we have successfully covered the most important features of Spring Framework. This foundation enables you to venture into more advanced features of Spring, packaged as Spring portfolio projects. Projects such as Spring Integration, Spring AMQP, Spring Cloud, and Spring Web Services solve the more complex problems of enterprise computing. With the knowledge you have gained from this book, you can now design powerful solutions using Spring Framework and its subprojects.
